Good dogs: A look at the newest Unitree quadrupeds

Good dogs: A look at the newest Unitree quadrupeds

When people think of robots, they often picture industrial robotic arms doing repetitive work on assembly lines: Precision welding, picking and placing objects – those sorts of applications. Or perhaps a wheeled platform carrying a load from one location in a factory to another.

In recent years, however, new algorithms and technologies have led to an increase in the number of quadruped robots. These are the four-legged devices that inevitably remind observers of dogs, since they have roughly the same shape and move with a similar gait. They’re also (depending on the robot) roughly the same size as medium to large dog breeds.

The most well-known of these is likely Spot, built by Boston Dynamics. Built primarily for industrial inspections, this machine has also taken the spotlight (excuse the pun) with choreographed performances with the likes of Cirque du Soleil.

In fact, videos of Spot dancing proved so viral that Boston Dynamics produced a video to clarify that its robot is capable of much more:

THE QUADRUPED ADVANTAGE

 

Why four legs? Why not just wheels, like most mobile robotic platforms?

Good question. And we put that to InDro Robotics Account Executive Luke Corbeth.

“In most predictable environments, wheels or tracks will suffice,” he says.

“Quadrupeds excel at unpredictable terrain. You can start looking at complex infrastructure like refineries, where there might be stairs or pipes that need to be stepped over. Quadrupeds are also suitable for Search and Rescue, where there might be rubble on the ground or potentially unsafe conditions. Robots like these are very good at navigating terrain that would be impossible for a robot with wheeled or tracked locomotion.”

 

UNITREE

 

Unitree Robotics is one of a small but growing number of firms specializing in these robots. Its founder is Wang Xinxing, an engineer who started working on quadrupeds roughly a decade ago at Shanghai University. He built his first quadruped, XDog, by designing and building virtually everything, including motor drive boards, the master-slave architecture, the legs – and more.

All that hard work led to the founding of Unitree in 2016. And Wang and his team of engineers have never stopped trying to push the envelope. As the Unitree website explains, the company puts a heavy emphasis on R&D:

“Unitree attaches great importance to independent research and development and technological innovation, fully self-researching key core robot components such as motors, reducers, controllers, LiDAR and high-performance perception and motion control algorithms, integrating the entire robotics industry chain, and reaching global technological leadership in the field of quadruped robots. At present, we have applied for more than 150 domestic patents and granted more than 100 patents, and we are a national high-tech certified enterprise.”

We’re going to explore two new models from Unitree in just a moment, but it’s worth taking a look back at the early days. This video was uploaded seven years ago – after XDog was already in development for more than a year.

 

THE GO2

 

One of the new Unitree quadrupeds is the GO2. This is a step up from the GO1 EDU, which has been popular for research and development, corporate innovation parks, and even entertainment. (Yes, like Spot, the GO series can also dance – but they also do *much* more than that.)

The GO2 is a significant redesign from the GO1 series. Unitree has dropped some of the multiple cameras from the GO1 and developed its own LiDAR module, called the L1. It features a 360° x 90° hemispherical capture. With a minimal blind spot, Unitree says the GO2 is 200 per cent better at recognizing its surroundings than the GO1 series. It can detect surroundings as close as .05m away.

Because of the LiDAR, it’s obviously capable of mapping even unfamiliar surroundings and avoiding obstacles, meaning it’s perfect for Simultaneous Localization and Mapping (SLAM) applications. In conjunction with that LiDAR, the GO2 features the new NVIDIA Orin Nano for powerful onboard AI-enhanced EDGE computing

“From my experience, the LiDAR does a much better job at SLAM than the depth cameras on the previous models,” says Corbeth. “The obstacle avoidance is really good out-of-the-box and it can obviously be improved on with development (GO2 is Open Source). And the Orin is a really notable upgrade when it comes to computing power.”

 

INTERNAL AND EXTERNAL AI

 

One of the more intriguing features is that the GO2 is integrated with Chat GPT and can respond to voice commands. You could ask it to explain Einstein’s Theory of Relativity and it would speak the answer to you. More useful, though, is that you can instruct the GO2 to carry out certain tasks by voice.

“If you say: ‘Hey, go back to where I first turned you on,’ then it’s going to return home. So that’s a practical use. This is one of the first robots that can accept voice commands out-of-the-box and literally action some of those voice commands.”

You can even ask GO2, viat Chat GPT, to generate code for new tasks. Think about that for a moment.

It’s also capable of wireless charging. The GO2 can rest itself on a small optional pad and be ready for its next mission without human intervention. There’s also an option for a servo arm if a manipulator is useful for your application. It’s faster than the GO1 EDU, capable of trotting along at 5 metres/second. The GO2 also has a significantly longer run time – between two and four hours, depending on how strenuously it’s working. Battery capacity and endurance have jumped by 150 per cent compared to the previous model.

“The locomotion – their internal algorithm for how the robot moves – is much improved. So it can go faster, it’s more reliable, it’s quieter,” adds Corbeth. Firmware upgrades are OTA (over the air), with user authorisation. The GO2 connects via 4G, Wi-FI6 and Bluetooth.

Unitree Go2 Quadruped

USE-CASES

 

Though the GO2 could be used for basic industrial applications, it’s intended more for R&D and education (there’s even the option of drag-and-drop block coding). InDro Robotics is also capable of modifying the robot with our InDro Backpack – which enables data-dense 5G operation with an easy-to-use dashboard and comprehensive documentation. The Backpack also contains USB slots for additional sensors, as well as the Robot Operating System (ROS) code necessary for seamless integration.

“Anything the GO1 could do, the GO2 can do better, faster, longer,” says Corbeth.

There are even variants available – the GO2 Enterprise and GO2 Enterprise Plus – with some additional bells and whistles intended for law enforcement, Search and Rescue and other First Responder applications. Those features include dual backup communication links, a searchlight and emergency flashing lights, an additional camera and the ability for two-way voice communication.

Here’s a look at the basic GO2 in action:

THE BIG DOG

 

Unitree’s other new quadruped is the B2. It’s an incredibly powerful, enterprise-level machine that can be deployed in even the most demanding conditions. Use-cases include:

  • Industrial asset monitoring and surveillance
  • Search and Rescue/First Responder work
  • Carrying heavy payloads/cargo over even rough terrain
  • Working in water (Ingress Protection rating IP67)

Capable of moving at 6 metres per second (21.6 km/hour), Unitree says the B2 is the world’s fastest enterprise-level quadruped.

“That’s really fast – like ridiculously fast,” says InDro’s Corbeth.

“The B2 is designed less for development and more for real commercial applications. It’s also Open Source, which differentiates it from quadrupeds like Spot, or those made by Ghost Robotics,  ANYmal, etc. So we have the option to deploy proprietary software on it that we’ve built and designed, or our partners have built and designed.”

Like its predecessor the B1, the size of the B2 is striking. It weighs 60 kg and measures 1098mm x 450mm x 645mm.

B2 Robot

INDUSTRY-READY

 

Straight from the box, the B2 is ready for a variety of use-cases. With strength and endurance, this machine has been tested carrying a 45 kilogram load 7.98 kilometres on a single charge (or 20kg more than 15 km). If it’s not carrying a load, it can walk more than 20 kilometres non-stop.

The B2 can handle slopes of 45° with ease, even in rough terrain. It can even walk on greasy or oil-covered floors without falling down. (You’ll see an impressive demo involving banana peels shortly.)

Unitree has measured a 170 per cent improvement in joint performance over the B1, with 360 Nm (Newton-metres, or 265.5 foot-pounds) of torque. Run-time is vastly improved, with the B2 capable of operating between four and six hours on a mission (depending on terrain, payload and speed). The heavy-duty battery is designed for rapid swapouts, and the option of autonomous wireless charging via pad is an option.

From the factory, the B2 is equipped with a 32-wire automotive-grade LiDAR, two depth cameras, a high-resolution optical camera, and a high-capacity 45Ah (2250Wh) battery.

“And the B2 can be further customized, either directly from the factory or by InDro Robotics for specific use-case scenarios,” says Account Executive Corbeth. “We can integrate additional sensors, including thermal and even gas-detecting modules according to client needs. And, of course, we can also outfit the B2 with the InDro Robotics Backpack, which enables 5G operation and allows for rapid integration of additional sensors.”

All of those are great options to have, but Corbeth emphasizes “this quadruped is also capable of starting work straight out of the box.”

 

BUILT TOUGH

 

Make no mistake. This robot has been built to thrive in punishing conditions, including operating in water. It’s also very strong, capable of bearing a load of 120kg while standing. Control and perception are managed by multiple processors, including an NVIDIA Jetson Orin NX, three Intel Core i7s and an Intel Core i5. (These can vary if you’re looking for a custom factory build.) Plus, of course, InDro has expertise in modifying all of the Unitree quadrupeds pending client needs.

“InDro Robotics does have the ability to outfit these with any sensors that aren’t standard from Unitree,” explains Corbeth.

Plus, there’s also the option of wheels. The lower legs can be swapped out with wheeled versions. If the B2 is operating on flat terrain these are more efficient than walking.

“This option combines the best of both worlds between a legged and a wheeled robot – you get the speed and efficiency of a wheeled robot, yet with the other legs it can also climb stairs and manage rubble or other obstacles on the ground,” he adds.

And how does this new machine compare to the competition? Unitree says its measured parameters are superior – and there’s agreement from Corbeth.

“Compared with Spot, ANYmal and Ghost Robotics, I think we’re very competitive on the hardware side. I actually think Unitree has got to the point hardware-wise where it’s now superior to pretty much all the other options.”

Have a look for yourself:

INDRO’S TAKE

 

As a North American distributor for Unitree, we obviously have faith in their products. We’ve also been partnered long enough to see the company’s commitment to continuously and meticulously advancing its products. These are excellent and durable quadrupeds, as our many clients will attest.

InDro also takes pride in supplementing Unitree’s documentation to get clients up and running quickly, and on those rare occasions when something goes wrong – we know how to repair them.

“Unitree is quickly becoming a world leader in the quadruped sector,” says InDro Robotics CEO Philip Reece.

“The new models are exceptionally well-built, with significant gains in power, run-time and processing abilities. Plus, add-ons like the InDro Backpack make these quadrupeds even more versatile for virtually any use-case scenario.”

TLR – Technology Readiness Levels – explained

TLR – Technology Readiness Levels – explained

Dec 4, 2023 | Engineering, InDro News, Industry News, Scott Simmie

By Scott Simmie

 

So: You’ve got a great idea for a new technology product or process.

That’s the first step: A concept that you’ve put some thought into. Of course, there’s a long road ahead before that brilliant idea becomes an actual commercial product. But how do you gauge that progress as you move along the development path? How would you describe where you’re at in a way that others might quickly grasp?

Luckily, there’s a tool for that. It’s called the Technology Readiness Levels scale, or TRL.

“It’s a standard measuring stick for everyone to communicate where they are with development,” explains InDro Robotics Engineering Lead Arron Griffiths.

The TRL tool was first developed by NASA researcher Stan Sadin back in 1974 with seven basic levels. It would take another 15 years before the levels were formally defined, during which time two additional levels were added. There are now nine steps up the ladder, where TRL 9 is the equivalent of a working product that could be mass-produced or commercialized.

Which means, of course, that Level 1 is at the very beginning of the technology development process.

“Level 1 is universally seen as a napkin idea – where you’ve jotted down a concept,” says Griffiths.

That’s a perfect analogy for TRL 1.

For greater clarity, each level on the scale offers a short definition, a description, and examples of activities. The short definition for Level 1 is “Basic Principles Observed and Reported.” The description is “Lowest level of technology readiness. Scientific research begins to be translated into applied research and development (R&D).”

In terms of examples, Level 1 “Activities might include theoretical studies of a technology’s basic properties.” And yes, that could include a napkin sketch.

MOVING UP THE SCALE

 

Great! You’ve got that napkin sketch done.

Obviously there’s a lot to do between that initial idea and a finished product suitable for commercialization. To get to TRL 2, you simply need to put more thought into it. You’re not actually building or programming yet, just putting greater clarity and focus on what you hope to accomplish.

TRL 2 is defined as “Technology concept and/or application formulated.” Here’s its description:

“Invention begins. Once basic principles are observed, practical applications can be invented. Applications are speculative, and there may be no proof or detailed analysis to support the assumptions.”

You could think of this stage as refining the idea, with activities limited to research and/or analytical studies.

TRL 3 means you’re actually beginning the R&D process. This might include some lab or analytical studies. At this stage you’re trying to validate predictions you’ve made about separate elements or components of the technology. The components you’re working with aren’t yet integrated – nor is it expected that the components you’re working with are at their final version.

TWO TRL SCALES

Before we move along, it’s worth noting there are actually two different TRL scales in use. The first (and the one we’re using here) is the NASA scale. But the European Union has its own TRL scale. 

“So there is some cloudiness,” explains Griffiths. “Typically the top and bottom of the scales are the same, but the middle moves around a bit. You have to be sure people are reading from the same scale. Typically when I talk to a client, I will show them the scale I am using.”

Griffiths also emphasizes that during R&D, the phase of development doesn’t always slot neatly into one of the TRL stages. 

“It’s typical to say: ‘We’re roughly about TRL 6’ – it’s not an exact science.”

Below: The InDro Commander module, with LiDAR sensor. This popular commercial product, which allows for rapid integration of ROS-based robots and sensors (and more), is TRL 9.

Teleoperated Robots

CLIMBING THE LADDER

 

American inventor Thomas Edison once said: “Genius is one per cent inspiration and ninety-nine per cent perspiration.” The same could be said of the process of inventing a product for commercialization. Once that napkin sketch is done (the one per cent), there’s still a lot of methodical slogging ahead. (Trust us, we know.)

TRL 4 is the stage where you’re putting things together. Basic components are integrated and readied for testing in a simulated environment. The short definition, via Canada’s Department of National Defence, is “Component(s)/subsystem(s) and/or process validation in a laboratory environment.”

The logical progression continues with the next step.

“TRL 5 means it’s ready for testing in a lab environment,” explains InDro Lead Engineer Griffiths. He also adds that this middle stage – TRL 4 through 7 – “is always the difficult part.”

Once TRL 5 is passed, it’s time to start seeing if the integrated components will work together in a simulated or lab environment. At this stage, TRL 6, the product is considered to be getting pretty close to its desired configuration. Yes, there will be further tweaking to come, but you’re getting there.

Below: InDro’s Street Smart Robot (the large white unit). The product has been built but not yet deployed in winter conditions. This would be at TRL 7. Every other robot in this image would have made it to TRL 9.

 

SSR Street Smart Robot

NEARLY THERE!

 

All that hard work has been paying off. Your product is assembled and has been tested in simulation or other lab environment. Now it’s time to get it out into the real world to see how it performs. Congratulations, you’ve reached TRL 7, where “Prototype system [is] ready (form, fit, and function) for demonstration in an appropriate operational environment.”

“TRL 7 is more like a long-term deployment. Once you can show it to be working in a real-world environment – outside of the lab – then you get to Levels 8 and 9,” says Griffiths.

These final two levels are usually pretty exciting. Once the product/solution has been proven to work in its final form – and in the environment where it’s expected to be deployed as a product – you’ve reached TRL 8. Just one more to go.

 

THE FINAL LEVEL

 

Remember that Street Smart Robot you just saw a picture of? Well, it’s ready to go. And once the wintry conditions take hold in Ottawa, we’ll be operating that machine in ice and snow on Ottawa streets. Specifically, on bike lanes in Ottawa, where it will detect hazardous conditions (including potholes) that might pose challenges for safe cycling. City of Ottawa maintenance crews will then be notified of the problem (and its location) so they can address the issue. (You can read more about the SSR here.)

And once the SSR is operating smoothly in those intended conditions? We will have achieved TRL 9, meaning “Actual solution proven through successful deployment in an operational setting.”

NOT ALWAYS A SMOOTH PATH

 

It’s easy enough to describe these levels. And in doing so, it can appear to be a straightforward, linear path where engineers move seamlessly from one level to the next. Reality is not quite so simple. Depending on the project, progress in the early stages can be made very rapidly.

“Most people get up to Level 5 fairly quickly,” says Griffiths. “You can even get to Level 5 in a day if you’re doing software development – you can literally go from an idea all the way up to a basic rudimentary prototype.”

But – as flagged earlier – things get a little trickier once you hit those middle levels.

“You can think of it as walking up a hill to Level 5,” he says. “Then there’s this valley. A lot of stuff dies in Level 6 and 7. There’s not a lot of success there because once you push the technology into actual environments the success rate is very low. So a lot of time is spent in Levels 5 and 6 trying to make a system that can make it to Level 7 successfully, and then on to Level 8 – where you’re essentially across the valley.”

Below: A graphic outlines the short definitions of Technology Readiness Levels

Technology Readiness Levels

INDRO’S TAKE

 

The TRL scale is extremely useful in the R&D world, in that it concisely conveys where a product is along the path to commercial development. And while it’s great for engineers, it’s also useful to help clients understand where one of our products is along that journey.

We’ve scaled this ladder many times over the years. Sometimes it’s a relatively easy climb. But, like all Research and Development companies, we’ve also had a few products that never made it beyond the valley Arron Griffiths described. That’s R&D.

“The Technology Readiness Level scale is a really useful tool, and part of our daily language at InDro Robotics,” says CEO Philip Reece. “Each level represents unique challenges – and that valley Arron described can sometimes be a disappointing bit of landscape. But we learn something even with the occasional failure.

“Thankfully, we have a creative and tenacious engineering team that seems to thrive on difficult challenges – and InDro now has a growing stable of products that have achieved TRL 9 and gone on to commercial success.”

If you’re working on your own project and would like to know where it is on the TRL scale, you can use this assessment tool from Industry, Science and Economic Development Canada.

 

That’s a wrap: Another great Aerial Evolution Association of Canada Conference

That’s a wrap: Another great Aerial Evolution Association of Canada Conference

Nov 20, 2023 | Aerial Evolution Association of Canada, Drone Detection, Industry News, Scott Simmie

By Scott Simmie

 

What a great show.

The Aerial Evolution Association of Canada (formerly Unmanned Systems Canada – Systèmes Télécommandés Canada) held its annual conference and trade exhibition November 7-10 in Ottawa. The event had an excellent turnout, along with the usual selection of high-quality learning sessions.

There was plenty of discussion around the coming world of Advanced Air Mobility, where new and transformative aircraft (many of which are innovative new autonomous drone designs with detect-and-avoid features) will routinely deliver heavy cargo and even passengers over dense urban centres and to regional communities not currently served by traditional aircraft.

Another timely topic was the increasing use of drones in the conflict in Ukraine, as well as the latest developments in Counter-UAS technologies (including both detection and mitigation). There was even a live demonstration of a new kinetic C-UAS drone that uses a net to disable and capture a rogue RPAS.

Reps from Transport Canada and NAV Canada were on hand to discuss proposed changes on the regulatory landscape and – always an important part of these gatherings – hear questions and concerns directly from the industry. These open exchanges have long been a hallmark of the annual event.

AEAC Plenary

FIRST NATIONS

 

There was a notable emphasis this year on Indigenous use of drones and other technologies, including a powerful session about detecting unmarked burial sites on the grounds of former residential schools. The concept of data sovereignty – who owns data captured on unceded territories – was also discussed. There was even a presentation on how drones have helped to capture important First Nations cultural events. Plus, of course, the employment and opportunities that RPAS education and initiatives are creating for Indigenous entrepreneurs and communities.

Below, one of the Indigenous panels, moderated by Kristin Kozuback (C)

DRONES AND LAND MINES

 

SAIT‘s Shahab Moeini talked about a program using UAS to detect land mines using AI, machine vision and sensor fusion. Many previous and current efforts have used magnetometers, but these metal-detecting sensors are neither effective nor appropriate given that many land mines are made of plastics and other non-metallic materials. Machine Learning is being used to train drones to recognise the many, many, different types of land mines – even if only a portion of the device is visible above ground.

“Land mines,” said Moeini, “are the nastiest creation of mankind.”

Below: Shahab Moeini, who runs SAIT’S Centre for Innovation and Research in Unmanned Systems (CIRUS)

SPEXI

 

Among the many excellent and innovative presentations, one by Spexi Geospatial caught our attention. The Vancouver-based company has built software that allows pilots of micro-drones to automatically fly and capture hexagonal-shaped areas the company calls “Spexigons.” Each Spexigon covers 22 acres and when an adjacent Spexigon is flown the data and imagery are seamlessly connected. With enough Spexigons captured, you’ve got a high-resolution version of Google Earth – and a ton of use-cases for the data.

The Spexi software carries out the flights automatically using DJI sub-250g drones, flying standardized capture missions to produce imagery at scale. The data is uploaded to the cloud where it’s stitched together to form highly detailed images of very large areas with a resolution of 3cm/pixel. (A satellite, by contrast, captures at 30cm/pixel while a standard airplane generally captures at 10cm/pixel.)

During one recent mission, “over 10,000 acres of imagery was captured in three days,” explained Spexi COO Alec Wilson.

“We’ve made it super simple to get images in and out at scale… And we’re super-excited to be able to start building bigger and better platforms for the drone industry.”

Below: Spexi’s Alec Wilson explains how the system works…

WOMEN IN DRONES

 

This year’s conference saw an increased emphasis on Women in Drones.

Though this has been on the agenda at past events, the 2023 event had somehow a different feel: The recognition that women are not only increasingly entering and shaping this male-dominated sector, but that many are high-level subject matter experts making significant contributions.

While progress has been made, there’s still work to do on the equity front. And there was a strong sense the AEAC is committed to achieving that.

Below: The close of the Women in Drones breakfast

RECOGNITION

 

One of the most memorable parts of any Aerial Evolution Association of Canada conference is the awards ceremony. Individuals and organizations that have made outstanding contributions to the RPAS industry are nominated, voted for by their peers, and selected for recognition. Recipients range from student engineers (the RPAS CTOs of tomorrow) through to service providers, manufacturers – and even government agencies.

Those honoured at this year’s conference include:

  • Dr. Frederique Pivot: Pip Rudkin Individual Achievement Award
  • Jacob Taylor: 2023 Indigenous Innovation Award
  • National Research Council of Canada Aerospace Research Centre: 2023 Organizational Achievement Award
  • Bryan Kikuta, Toronto Metropolitan University: 2023 Mark Cuss Memorial Scholarship
  • Ana Pereira, University of Victoria: Best Student Oral Presentation Award (judged)
  • Aman Basawanal, Carleton University: Best Student Technical Paper Award (judged)

Below: The National Research Council Team receives its award

WAIT, THERE’S MORE

 

There was one more award recipient to whom we’d like to give a special shout-out. It’s Katelin (Kate) Klassen, who received the 2023 Aerial Evolution Ellevatus Award “for her outstanding dedication in uplifting, empowering, and inspiring women in the Canadian RPAS sector.”

Kate is truly a pioneer in this field. A multi-rated private pilot and flight instructor with traditional aircraft, Kate has been a significant force in the drone field for years. She’s an educator (her online courses have trained more than 10,000 pilots), a lobbyist (she’s taken part in multiple consultations with regulators – including being co-chair of the CanaDAC Drone Advisory Committee), and a true advocate for RPAS education. Her knowledge of the Canadian Aviation Regulations (CARs) is legendary – and she has inspired and encouraged countless women (and men) in this industry.

Plus, she’s truly an all-round awesome human being – always willing to share her time and expertise. Congratulations, Kate – and all the other winners!

Kate (C) looking justifiably happy…

Kate Ellevatus

ALSO WORTH NOTING (AND CELEBRATING)

 

Though they didn’t receive any awards, three key members of the Association certainly merit public recognition for their contributions. Jordan Cicoria (CEO of Aerium Analytics) did an outstanding job as Conference Chair. In fact, he’s overseen the last two in-person conferences, while also taking the helm of the virtual gathering during the peak of the pandemic. That’s a *lot* of work, and Jordan has carried out these tasks both professionally and modestly while juggling a plethora of moving parts.

A lot of work on the conference – and elsewhere – came from AEAC Executive Director Declan Sweeney. Declan worked hard behind the scenes (and on countless calls) with sponsors, exhibitors, membership drives – you name it. He’s also deeply involved in the annual student competition. Declan does it all with professionalism, and a great sense of humour.

Equally deserving of recognition is AEAC Chair of the Board Michael Cohen (also the CEO of Qii.AI).

Michael has been serving the Association well, and was key in the transition and rebranding from Unmanned Systems Canada / Systèmes Télécommandés Canada to the Aerial Evolution Association of Canada. This was far more than a name change, but an organizational shift to reflect the coming era of Advanced Air Mobility. He’s been instrumental in the Association’s push toward greater Diversity, Equity and Inclusion – which was reflected in the conference agenda.

The Association also benefits greatly from Michael’s extensive knowledge and background; he’s a former commercial jet pilot – a distinct advantage when discussing the Big Picture (and the minutia) with regulators.

Thank you, all.

INDRO’S TAKE

 

As always, we were pleased to participate at the annual Aerial Evolution Association of Canada conference. In addition to the sessions, the networking and the trade exhibit – it’s of tremendous value to have the industry and the regulators together for collaborative discussions. There’s been tremendous progress in this sector over the past decade, and much of that is due to regulators truly working with the industry to safely advance RPAS use in Canadian airspace, including BVLOS flight and other more complex operations. Technology that was seen almost as a threat in the early days is now being accepted as a useful – and critical – adjunct to the overall world of aviation.

InDro Robotics staff appeared on multiple panels; CEO and AEAC Board Member Philip Reece, pictured below, took part in the Counter-UAS panel and a live demo of kinetic C-UAS drone at Area X.O‘s Drone and Advanced Robotics Training and Testing (DARTT) facility. (That’s Philip below.)

Philip Reece

BUT…

 

We’d be lying if we didn’t tell you that a true highlight for us was seeing Kate Klassen receive the Ellevatus Award.

“One might easily conclude we’re happy simply because Kate is a flight instructor and regulatory expert with InDro Robotics,” says CEO Philip Reece. “But that’s really just a sliver of the truth. Kate’s contributions over the years have been plentiful, significant, and lasting. We’d be applauding this recognition just as loudly even if she didn’t work with InDro.”

We are, however, very happy – and fortunate – that she does.

 

YOW Drone incident recounted in WINGS magazine

YOW Drone incident recounted in WINGS magazine

Nov 20, 2023 | Drone Detection, Industry News, Scott Simmie, YOW

By Scott Simmie

 

If you follow the news from Indro Robotics regularly, you’re likely aware we’re the key technology provider for the YOW Drone Detection Pilot Project.

For several years, we’ve been involved in detecting drones flying in proximity to the Ottawa Macdonald-Cartier International Airport. The data is collated into regular reports and shared with partners including Transport Canada, NAV Canada and the RCMP. It has also proven invaluable in assisting YOW with developing protocols for drone incursions and even apprehension of individuals violating RPAS airspace rules.

Among the project highlights we’ve covered in the past:

These stories have been picked up by multiple news outlets in the past, including the Ottawa Citizen, CBC  News, sUASNEWS, DroneDJ – and many more. In fact, here’s one those CBC pieces, covering the drone detection used during President Joe Biden’s visit:

THE YOW INCURSION

 

One 2022 incident at YOW, where the pilot was caught in the act, has received a lot of attention throughout the industry. The operator was ultimately fined $3021 for violating a number of rules laid out in the Canadian Aviation Regulations (CARs).

The incident not only proved the real-time capabilities of the technology (including its ability to locate the pilot), but highlighted the many specific regs that had been violated. Transport Canada investigated and ultimately issued significant sanctions – a cautionary tale for those who might be uninformed about or wilfully violate the strict rules governing RPAS use in close proximity to airports/aerodromes etc.

This week, we noticed WINGS Magazine highlighted the story in its November/December edition.

WINGS YOW

PLAY-BY-PLAY

 

The data obtained during that December 2022 incursion is highly detailed. In fact, it offers a moment-by-moment description of how the flights went down (and up), along with how YOW authorities responded to the event. You can find the WINGS article online here, but we’ve also pasted it below for your convenience.

Apologies for the split headline, but this was a double-truck page.

WINGS YOW INCURSION ONE
WINGS YOW INCURSION TWO

INDRO’S TAKE

 

We’re grateful to WINGS Magazine Editor Jon Robinson for amplifying our YOW drone incursion story. The more that incidents like these are publicised, it’s reasonable to assume that fewer will occur as people learn more about the regulations and penalties.

It’s also clear, as was demonstrated at the 2023 Aerial Evolution Association of Canada conference, that drone mitigation technology continues to improve. During the event, there was a demonstration of a drone that can track down and disable a rogue RPAS with the kinetic firing of a net.

Elroy Air’s Chaparral brings long-range, heavy lift cargo solution

Elroy Air’s Chaparral brings long-range, heavy lift cargo solution

Nov 16, 2023 | Advanced Air Mobility, Autonomy, Industry News, Scott Simmie

Some history has just been made in the world of Advanced Air Mobility (AAM).

On November 12, Elroy Air successfully flew its Chaparral C1 – the first flight of a turbogenerator-hybrid electric vertical take-off and landing (hVTOL) aircraft. The hover test of the full-scale aircraft took place at the company’s test-flight facility in Byron, California.

It’s an important milestone as the world moves toward the AAM era, when new and transformative aircraft will move goods and people to destinations that would have been impractical or too expensive using traditional aircraft.

“This is an exhilarating day for our team and the industry as a whole,” says Elroy Air co-founder and CEO Dave Merrill.

There are plenty of companies competing for this new space with innovative autonomous designs. Some are designed to carry people, cargo, or both. There are several excellent designs out there, but Elroy Air’s Chaparral C1 has been on our radar for reasons you’re about to discover.

Before we get into the history, though, let’s get straight to the news. Here’s a video of the test flight:

AND DOWN ON THE GROUND

 

Check out the Chaparral C1 on the ground. Take a good look, as we’ll be discussing these features.

THE CHAPARRAL

 

Let’s get into why this aircraft will fill a niche.

It’s been designed to move large payloads long distances – and do so efficiently. Humanitarian aid, military resupply and middle-mile logistics are all perfect use-cases for the Chaparral. Its sole purpose is to move significant amounts of cargo efficiently – and be ready for the return trip in minutes.

Here’s the one-floor elevator pitch:

“We’re building an aircraft that will be able to fly 300 miles (483 km) and carry 300 pounds (136 kg) of cargo,” explains Jason Chow, the company’s Director of Strategy and Business Development.

“It’s VTOL, so we don’t need runways. It’s also hybrid electric, so in many situations where there are remote areas, we’re still able to fly where electric power is unavailable.”

Hybrid electric makes sense when you’re after this kind of range, since the craft benefits from the energy density of jet fuel.

“A turboshaft engine powers the batteries, and the batteries power flight,” says Chow.

“One of the most intensive parts of flight is the takeoff portion, where you’re vertically flying upwards. And once you get into forward flight, the turbine is able to throttle back to meet the reduced demand while maintaining battery charge.”

As you can see from the photo, there are eight motors for vertical lift and four for forward propulsion. Once the craft transitions into forward flight, its fixed-wing design brings greater efficiency and range than would be possible with a traditional multi-rotor (which don’t generally have lifting surfaces aside from the rotors themselves).

But while all this looks great, Chaparral’s real secret sauce is its cargo capabilities – which have been designed, literally, from the ground up.

Take a look again at the photo above. Note the design of the wheel struts, as well as the ample space between the bottom of the fuselage and the ground. That’s all for a very specific reason: Chaparral has been designed to carry an aerodynamic, quickly-swappable cargo pod.

Have a look:

THE POD

 

Chow says the system is comparable to a tractor-trailer. On a road, the tractor provides the power to move the goods. In the air, “the trailer is the equivalent of the cargo pod. We imagine customers will have multiple cargo pods.”

Those pods can be quickly interchanged on the ground – because the Chaparral’s autonomy abilities aren’t limited to flight. The aircraft can taxi to a predetermined location, lower and disengage a cargo pod, then reposition itself and pick up the next one. You can imagine the advantage of such a system when transporting food or critical medical supplies in an emergency situation. This isn’t simply an aircraft: It’s a delivery system.

It’s also worth noting that the pod has been designed to be compatible with existing infrastructure and tools such as forklifts. As the Elroy Air website explains:

“The Palletized Pod uses a fairing-on-pallet design to ease loading of heavy cargo. This configuration features a standardized L-Track system for securing shipments, ensuring simple loading and safe travel for hefty items.”

BUSINESS MODEL

 

So, will Elroy Air be a service provider, overseeing autonomous flights for clients? Or will it be producing the Chaparral to be sold to clients who will operate it themselves?

“The current thinking is that we would do both,” explains Chow. “There are a lot of our partners that are very good at operating aircraft: FedEx, Bristow, the United States Air Force. The main thing they do is operate aircraft really well. So in those situations we would sell to them only as the OEM (Original Equipment Manufacturer).”

“But we also have customers who are interested in what we can provide. So in those situations we could provide the service ourselves or rely on very experienced operators.”

MANUFACTURING

 

Producing an aircraft of this scale – it has a wingspan of 26.3 feet (8.01 metres) and a length of 19.3 feet (5.88 metres) – is no small task. Elroy Air made the decision early on that the most efficient approach would be as a highly selective and meticulous integrator. So its composite fuselage, for example, is outsourced.

“There are folks in the general Advanced Air Mobility industry that are building everything in-house. That’s great, you can own the IP (Intellectual Property) for everything,” says Chow.

“That being said, it takes longer. So our approach has been to be an integrator. We source the best parts to help us get to market – including the generator.”

TRAJECTORY

 

There are a lot of startups in this space, including plenty of newcomers. Elroy Air was formed back in 2016 in San Francisco by Dave Merrill (now CEO) and Clint Cope (Chief Product Officer).

By 2018 the company flight-tested sub-scale Chaparral aircraft and user-tested its automated cargo‑handling systems. The following year it had established a relationship (and contract) with the United States Air Force “enabling Elroy Air to understand and inform the USAF’s operational needs for distributed aerial logistics in contested environments. We developed our custom simulation environment for Chaparral aircraft and ran a successful flight test campaign on an early 1200‑pound, full-scale Chaparral prototype outfitted with an all-electric powertrain.”

The milestones have kept coming. The year 2020 brought refinements to its simulation system, allowing the team to carry out thousands of virtual flights and ground/cargo mission experiments. Development began in earnest that same year on the hybrid-electric powertrain, including multiple turboshaft engine runs.

A Series A financing in 2021 brought in partners Lockheed Martin, Prosperity7 and Marlinspike, who came to the table with $40M. In 2022 an additional $36M in capital arrived, and the company unveiled its C1-1 Chaparral to the public. (The aircraft also made it to the cover of Aviation Week.)

It’s been a careful, methodical journey that has brought the company this far – and it clearly has ambitious plans for the future. If you’d like to read about these milestones in greater detail, you’ll find a company timeline here. 

But the biggest milestone so far? The flight that opened this story.

“This marks a major moment for the industry as hybrid-electric aircraft enable the dual benefits of runway-independent safe redundant propulsion, and long-range flight well in excess of battery power alone,” says co-founder and CEO Dave Merrill. 

“Our accomplishment puts Elroy Air one step closer to delivering a transformative logistics capability to our customers and partners.”

INDRO’S TAKE

 

We at InDro obviously have a stake in the future of Advanced Air Mobility. We know from our own work in this field of the pent-up demand for efficient VTOL aircraft that can safely shuttle critical cargo – whether across major cities or to isolated communities lacking runways.

We’ve also been watching, with interest, the companies that are vying for space in this coming market.

“From everything we’ve seen, Chaparral is going to be a perfect fit,” says InDro Robotics President Philip Reece. “It’s cargo capacity and range will really fill a void, and the pod system – complete with its autonomous coupling and decoupling feature – will be hugely advantageous. We congratulate Elroy Air on this milestone, and look forward to seeing a transition flight before long.”

As with all new aircraft, it will take time before certification takes place and the FAA gives Elroy Air its full blessings. We’re confident that not only will that day come – but that Elroy Air and Chaparral will play a significant role in the era of Advanced Air Mobility.

Engineers put skills to the test in F1tenth autonomous challenge

Engineers put skills to the test in F1tenth autonomous challenge

Oct 5, 2023 | Autonomy, Industry News, IROS, Scott Simmie

Want to win a scale model car race?

Normally you’d pimp your ride, slam the throttle to the max, and do your best at the steering control to overtake any opponents while staying on the track.

Now imagine a race where no one is controlling the car remotely. Where, in fact, the car is driving itself  – using sensors and algorithms to detect the course, avoid obstacles, and look continuously for the most efficient path to the finish line.

That’s the concept of F1TENTH, a regular competition held at major robotics conferences. The latest contest was carried out in Detroit at IROS 2023, the International Conference on Intelligent Robots and Systems. The contest brings together researchers, engineers, and autonomous systems enthusiasts.

“It’s about Formula racing, but on a smaller scale – and it’s autonomous,” explains Hongrui (Billy) Zheng, a University of Pennsylvania PhD in electrical engineering, and a key organizer of the F1TENTH series.

And what does it take to win?

“I would say 90 per cent software, and 10 per cent hardware,” says Zheng.

And that means it’s more about brainpower than horsepower.

Before we dive in, check out one of the cars below:

F1tenth

A LEVEL PLAYING FIELD

 

To keep things truly competitive, all teams begin with the same basic platform. They can either build that platform, based on the build guides at F1TENTH.org, or purchase the platform. The price of the vehicle, which this year incorporated a 2D LiDAR unit (which makes up the bulk of the cost), is about $2500-$2800 US.

“I would say 60 per cent is spent on the LiDAR,” says Zheng. “Some teams use a camera only, and that drives it down to around $1000.”

So it’s a lot more accessible – and a lot safer – than real Formula 1. And instead of high octane fuel, the teams are more concerned with powerful algorithms.

Once again, the basic Open-source Robot Operating System autonomy and obstacle avoidance software is part of the basic package that all teams start out with. But just as real F1 teams work together to extract every ounce of performance, so too do the F1TENTH teams, which usually represent universities but are occasionally sponsored by companies. At this year’s competition six of the nine teams were from universities.

The F1TENTH organization says there are four pillars to its overall mission. Here they are, taken directly:

1. Build – We designed and maintain the F1TENTH Autonomous Vehicle System, a powerful and versatile open-source platform for autonomous systems research and education.

2. Learn – We create courses that teach the foundations of autonomy but also emphasize the analytical skills to recognize and reason about situations with moral content in the design of autonomous.

3. Race – We bring our international community together by holding a number of autonomous race car competitions each year where teams from all around the world gather to compete.

4. Research – Our platform is powerful and versatile enough to be used for a variety of research that includes and is not limited to autonomous racing, reinforcement learning, robotics, communication systems, and much more.

In other words, there are real-world applications to all of this. Plus, for engineers, it’s not that difficult to dive in.

“The entire project is Open Source,” explains competitor Po-Jen Wang, a computer engineer from the University of California Santa Cruz. “It uses a Jetson Xavier (for compute). And for perception it uses a Hokuyo 2D LiDAR. Some people will mount a camera for computer vision. You can make it by yourself – it’s very easy to make.”

The following video provides a good introduction to the competition. In actual races, a piece of cardboard – sometimes modified for aerodynamics – is affixed to the rear of the car. These are to aid other vehicles on the track with obstacle avoidance.

 

PIMP THAT RIDE

 

Okay. So you’ve got your basic build, along with the basic ROS software.

Now it’s time to get to work. Engineers will add or modify algorithms for obstacle avoidance, acceleration, braking – as well as for determining the most efficient and optimal path. Depending on their approach, some teams will plot waypoints for the specific course.

Of course, like a real F1 race, a lot of modifications take place once teams are at the track. But in the case of F1tenth, those alterations tend to be code (though we’ll get to mechanical changes in a moment). Of course, scrolling through endless lines of programming isn’t the most efficient way to detect and eliminate bugs or improve efficiency. This is particularly true since multiple types of software are involved.

“There is software for SLAM (Simultaneous Localization and Mapping) for the mapping part, there’s software for localisation, there’s software for basic tracking if you give it a waypoint,” says organizer Billy Zheng. “Some of the basic drivers are found in a repository on Github.

“Most of the good teams are very consistent, and most of the consistent ones use mappingand localisation. The second place winner this year was using a reactive method – you just drop it and it will work.”

With all those moving parts, many teams use a dashboard that displays multiple parameters in real-time as the car moves down the track. This allows them to more rapidly nail down areas where performance can be optimised.

“The good teams usually have a better visualisation setup, so it’s easier to debug what’s going on,” adds Zheng. “The good teams are using Foxglove – a spinoff from an autonomous driving company that created a dashboard for ROS.”

To get a better idea of what the engineers are seeing trackside, here’s a look at Foxglove in action during F1TENTH.

MECHANICALS

 

Though it’s 90 per cent about code, that’s not all.

“Some modify their vehicles in different ways, maybe make it more aerodynamic, change the wheels,” explains competitor Tejas Agarwal, a graduate of uPenn with a Masters in Robotics. Agarwal and Po-Jen Wang were both contracted by Japanese self-driving software company/foundation Autoware.

(As it turned out, Wang and Agarwal placed second and third, respectively.)

The wheels on the stock vehicles are more suited to pavement and dirt rather than indoors tracks, so wheels are a common modification. But this year’s winning team, from Université Laval, took it further.

“We lowered the centre of mass as much as possible, changed the wheels, and changed our motor for better control,” says Laval team leader Jean-Michel Fortin, a PhD student in computer science specialising in robotics.

Of course, they weren’t allowed to increase the power of the motor in order to keep things on an even playing field. But they wanted one that offered greater control at lower speeds.

“Usually at low speeds the (stock) motor is bad, so we changed that for a sensor equipped motor,” says Fortin.

“We also replaced our suspension because it was too soft. As soon as we were braking our LiDAR wasn’t seeing what it should. For the software part, we tuned everything to the maximum that we could. We also optimised the race line to make sure the race line that we predict is as close to what the car can do as possible.”

And it paid off. The Laval team, pictured below, was clearly in a celebratory mood after winning (Jean-Michel Fortin in centre). Following is second-place winner Po-Jen Wang, third-place winner Tejas Agarwal and organizer Billy Zheng.
