InDro Robotics releases “NERDs” White Paper

InDro Robotics releases “NERDs” White Paper

By Scott Simmie, InDro Robotics

We’re pleased to release a White Paper detailing an ambitious and successful project we’ve recently completed.

That project, perhaps appropriately enough, goes by the acronym NERDS – which stands for Network Enhanced Realtime Drone project. It began as a technology challenge issued by the Ontario Centre of Innovation, whose mandate is to “develop and deliver programs that accelerate the development, commercialization, and adoption of advanced technologies to drive job creation.” The project included technical support from Ericsson and access to the ENCQOR network, a test-bed 5G network with a corridor through Quebec and Ontario.

The goal of this challenge? To greatly enhance capability of Enterprise drones and enhance the safety of Beyond Visual Line of Sight flights. The challenge involved designing, building and testing a module that would allow an Enterprise drone to be flown over the 5G network while transmitting even highly dense data in realtime. Some of the more specific goals included:

  • Drone Command & Control (C2) over 5G
  • Transmission of telemetry back to the control station: altitude, speed, compass heading, high-precision GPS, battery level, ambient temperature, barometric pressure, etc.
  • Transmit ultra low-latency, uncompressed 4K video stream via 5G
  • Use a Software Defined Radio to transmit to nearby traditional aircraft that a drone operation in the area is underway

There were other bits and pieces as well, but that sums up the core of the project.

Under the lead of engineer Ahmad Tamimi, InDro got to work. There was a ton of testing, simulations – even mapping out the strength of 5G signals at various altitudes – before we pulled the hardware and software together into a module compatible with any Enterprise drone using a Pixhawk flight controller.

Here’s generation one of that module, which we call InDro Capsule. It’s that black, hexagonal device on top of the drone.

 

Network Enhanced Realtime Drone Technology

Plug & Play

 

We are currently working on a commercial version of InDro Capsule. It won’t be long before we turn this into a product that will enable other Enterprise drones to be flown over 4G and 5G networks. That product will include the Software Defined Radio for alerting private aircraft to drone operations.

There’s actually much more to the system, which integrates into our new software platform, InDro Pilot. One of the more unique features of the InDro Pilot ecosystem is that it will allow Enterprise drone operators to quickly integrate other sensors, simply using a drag and drop interface. You simply select the appropriate module for the desired sensor.

We’re not going to jump into details here, but if you’re like more info about this system you’ll find it here. We will, however, give you a glimpse of how this works by showing you the Winch module:

Context

 

Now that you’ve got some background, we’ll get to the White Paper.

Like all White Papers, this one methodically details the scope of the project, the steps that were taken to achieve those goals, as well as the results. If you’re into the fine details of how a challenge like this gets accomplished, you’ll find plenty to interest you. It’s also a testament to the hard work of InDro’s engineering team – and Ahmad Tamimi in particular. Ahmad spent the early months of the COVID outbreak working on this project solo (along with virtual meetings with Ericsson).

The image below gives you a sense of the granular detail contained in the document.

InDro’s Take

 

At InDro, we love a challenge. And the NERDs project presented us, along with partners Ericsson, a significant one.

We believe the resulting InDro Pilot system (which includes the InDro Capsule module) will enable safer BVLOS flight. The 4K streaming and ultra low-latency enhance situational awareness for the pilot, and the Software Defined Radio will alert neaby aircraft to drone operations in the area. In addition, even dense data can be uploaded directly to the cloud during missions. Just as the InDro Commander offers a plug-and-play solution for customizing ground robots, InDro Pilot will do the same for Enterprise drones on the Pixhawk platform.

We are currently making InDro Capsule lighter and more compact, and look forward to commercializing the entire package in the near future.

Some innovative Canadian tech companies to watch

Some innovative Canadian tech companies to watch

At InDro Robotics, we live and breathe innovation.

Not only do we like creating new products and solutions, we enjoy celebrating when other companies – particularly Canadian companies – build cool things.

InDro Robotics recently took part in a Trade Mission sponsored by NRC-IRAP – the National Research Council’s Industrial Research Assistance Program. The program involved some 20 companies heading to Portugal for meetings with leading Portuguese innovation companies and agencies, as well as attending the Global Innovation Summit focussed on a sustainable future.

It was a busy, whirlwind week. But one of the highlights was meeting some of the other Canadian companies in the innovation space and learning more about that they do. So we thought we’d take a moment and highlight a few of them.

 

Oneka Technologies

 

See that buoy floating below? It’s pretty special.

Oneka Technologies
The buoy is built by Quebec’s Oneka Technologies. And it can turn sea water into drinking water, using wave power.

The Oneka system consists of buoys tethered just offshore from an area in need of fresh drinking water. The movement of the waves provides the energy to force the seawater through reverse osmosis filters. The result? Fresh water in places that need it most.

As the system performs its extraction, it also produces a brine containing roughly 30 per cent more salinity than the surrounding seawater. That brine is returned to the ocean, but quickly diluted.

Each buoy requires about 10 square metres of space on the ocean, so multiple buoys can be placed within close proximity. Use-case scenarios include communities with limited access to drinking water, natural disasters where the drinking water has been disrupted – and even seaside resorts in need of desalination.

$5.5M funding round

Last year, Oneka announced it had completed a $5.5M funding round led by Canadian investor Innovacorp and American investor Baruch Future Ventures.

“The world is running out of clean water and Oneka has a solution. It works, it’s affordable, it’s better for the environment, and it can be scaled from local disaster relief and regional demand all the way to meeting utility needs,” said Jonathan Saari, investment manager at Innovacorp in an Oneka news release. “It’s exciting to watch the team build and test their world-changing technology…”

The release says the company is working its first two commercial deploments in the US and Chile. Oneka’s solution produces zero CO2 emissions, and a single device can produce up to 10,000 litres of fresh water per week, enough for 450 people.

Earlier this year, Oneka won the US Department of Energy’s Waves to Water challenge, a competition designed to accelerate the development of small, modular, wave-energy-powered desalination systems. The three-year-long challenge netted the company $500,000 US.

Open Ocean Robotics

And here’s another Canadian company doing innovative things on the water.

Open Ocean Robotics is a Victoria-based company that really grabbed our attention during the Trade Mission trip.

Its solar-powered vehicle (with a patented self-righting system), can travel the ocean for months at a time, sending back critical data in real-time. The model seen here is called the Data Xplorer, and the company also has a model that utilizes rigid sails.

Oneka Technologies

Long-term missions, zero emissions

 

The Open Ocean robotics USV is suitable for long-range missions lasting months, with the vehicle capabale of either autonomous or remotely operated missions (pending how remote those missions are). Here’s what Open Ocean says about the device:

“Powered by the sun, it can travel on the ocean for months at a time collecting ocean and environmental data using its suite of sensors.  It sends this information back in real-time through secure communication systems and clients can control the USV from anywhere in the world using our user portal. Capable of travelling in both coastal and open-ocean waters, and with a customizable platform for multiple sensor integration, it offers the ability to understand our oceans in a whole new way.  Data Xplorer is designed to endure all sea states and is self righting.”

Here’s a look at Data Xplorer in action:

This appears to be a thoughtfully engineered system that can be teleoperated where there’s a cellular signal. In more remote areas, missions can be uploaded via satellite. We’re particularly impressed by the unique self-righting system. It relies on buoyancy in that circular structure at the stern, rather than adding weight to the keel (which would reduce efficiency).

And yes, these USVs can capture a *lot* of useful data: This graphic comes from the Open Ocean Robotics website.

Oneka Technologies
The company has carried out multiple successful missions to date; you can find case studies here. In December of 2021, Open Ocean Robotics wrapped a $4M seed funding round.

Perhaps even more impressive? CEO Julie Angus, in addition to holding multiple degrees (including a Masters of Science in molecular biology), was the first woman to row across the Atlantic Ocean, from mainland to mainland.

 

ACEL Power

 

The Vancouver-based firm focuses on what’s likely to be a booming market in the years to come: Electric outboard motors. The company says its motors deliver 30 per cent more torque than a comparable horsepower internal combustion engine, plus offer a lifespan five times that of a conventional outboard.

All that, with zero emissions.

The company is about to commence manufacturing, and is now taking pre-orders on 50, 60, 75, 100 and 150-horsepower motors. Motors come with the complete ACEL Power system, including:

  • Engine
  • Battery
  • Inverter
  • Throttle
  • Onboard Computer Screen
  • Keyless start Fob

Here’s a look at a prototype engine in action:

And while ACEL Power’s motors are not inexpensive, the company says they will outperform and outlast conventional motors. ACEL also has its eye on potentially producing a Uncrewed Surface Vehicle using its outboards down the road.

You can find more info – and even pre-order a motor – right here.

 

And finally…

 

A brief look at one more company from the trip (though we wish we had room to highlight them all).

Ashored is not in the robotics space, but it has a very intriguing product that will help prevent sea mammal entanglements and hopefully make life easier for people in the fishery industry who use traps for lobsters, crabs etc.

Normally, those traps are dropped to the bottom and attached by lines to small buoys on the surface. Those lines can often entangle whales and other sea creatures. In fact, if whales are spotted in areas where there are active traps, fishers can be instructed to remove traps until the whales move out of the area.

The Ashored system offers a clever solution. Its MOBI (Modular Ocean Based Instrument) keeps the line on the ocean floor until the fisher returns to collect the gear. The rope and small buoy are contained in a cage that is attached to the other traps. Using an acoustic signal (or timer), a magnetic lock is released and the buoy floats to the surface.

You can check out the system in this excellent video:

InDro’s Take

 

The companies on that recent trip, without exception, had impressive innovations and/or solutions. A lot of them were in the maritime space, where we’re seeing an increased use in robotics both on and beneath the surface.

There’s also a growing emphasis on sustainability, in conjunction with net-zero carbon emissions. There can be no doubt there are good use-cases for wave-powered desalination systems, solar-powered Uncrewed Surface Vehicles, electric outboard motors – and more. We look forward to seeing more from these Canadian companies, as well as the others who were on the trip.

In closing, a quick shoutout to Andrew Bauder, Léonie Hyppolite and Scott McLean from NRC-IRAP for organizing and excellent and productive Trade Mission. Thank you.

Meet InDro Pilot: A powerful 5G hardware and software suite for Enterprise drones

Meet InDro Pilot: A powerful 5G hardware and software suite for Enterprise drones

By Scott Simmie

 

Nothing turns our crank quite like developing something brand new; something that’s never been done before. That’s really the heart and soul of R&D.

And that’s also why we’re so excited about InDro Pilot – a new hardware/software solution created by InDro Robotics that will give Enterprise drones and their operators the equivalent of superpowers.

Okay, perhaps there’s some slight hyperbole in that statement. But there’s no question that InDro Pilot will dramatically expand the capabilities of drones using the Pixhawk flight controller, the standard in many Open-Source drones.

InDro Pilot enables operations over 4G and 5G, meaning you could pilot a drone from across the country (providing you have a visual observer with eyes on the flight or a Beyond Visual Line of Sight Special Flight Operations Certificate). It also enables the secure transmission of even highly dense data (such as 4K streaming video) directly to the ground or the cloud with minimal latency. No more pulling out MicroSD cards and waiting for uploads. Realtime data, while you’re flying the mission, sent where it’s required.

Needless to say, this didn’t happen overnight. Getting here required an immense amount of effort from our Area X.O R&D facility. And, in particular, the project’s lead engineer Ahmad Tamimi – seen here on the right. When this photo was taken in the fall of 2021, Ahmad was in the thick of developing the 4K streaming component of the system and integrating it on our Wayfinder drone (foreground).

 

Canada Robotics

There’s a backstory here…

 

The catalyst for InDro Pilot was a technology challenge. The Ontario Centre for Innovation, in conjunction with Ericsson and the ENCQOR 5G testbed, put out a call to Canadian technology companies to enable drone flights over 5G. What’s more, the challenge required the successful transmission of uncompressed 4K video – which will help enable Beyond Visual Line of Sight flights because it provides the pilot with greater situational awareness. There were other bits and pieces, which we’ll explore at a later date. Point is, being the successful applicant in this technology challenge is what started us down the InDro Pilot road.

As we explain what InDro Pilot is all about, we’re going to get into a few names of various components. But big picture? It’s a combination of hardware and software that collectively brings about both enhanced capabilities for the drone itself (ie 4G, 5G, dense data realtime uploads etc.) as well as enhanced options for the drone operator to further customize drone sensors and peripherals for any given missions via dashboard. 

Ahmad Tamimi pulled together this nifty graphic, which provides a high-level view of the system:

Drones Canada

The basics

 

In this post, we’re going to focus on InDro Captain and InDro Capsule.

Let’s start with the latter.

InDro Capsule is hardware, integrated into a capsule. Think of it as a box that can be easily attached to any Enterprise drone using a Pixhawk flight controller, because that’s what it is. That hardware includes:

  • A high-speed Quectel modem for transmitting even dense data to the ground and the cloud in real-time
  • A Jetson-based Edge processor
  • Specialized antennae for both data transmission and Command and Control
  • More IP-protected secret sauce we’ll unveil soon, which has significant implications for Detect and Avoid scenarios

InDro Captain, meanwhile, is the onboard software. It enables communication with the InDro Base (our ground station), secure data transmission to the ground or cloud, and can easily integrate peripherals like a winch or additional sensors.

And what does it look like? Well, the magic is contained within that hexagonal dome – and we’re currently making that dome smaller and lighter. Check out those wild antennae, chosen after a detailed calculations and simulations. And that white one with the InDro logo? We can’t wait to tell you what that one does.

Canada Drones

Another look

 

These pix were taken during the R&D phase of InDro Pilot, so they’re just quick phone grabs. But we have a feeling you’ll probably like to see at least one more:

Canada Drones

By the way, that’s a high-end mirrorless camera on that gimbal. With InDro Pilot on board, transmitting its uncompressed 4K output at minimal latency is a breeze.

When flying over 5G, the feed from this sensor (or any other) can be captured on the ground and simultaneously uploaded to the cloud. Our new InDro Link software (more on that later), securely integrates with third-party cloud services such as AWS, Azure, Google and more.

As 5G networks expand across North America and globally, this has significant implications for not only remote teleoperations and missions on private 5G networks, but also for realtime capturing of dense data. Providing there’s a 5G network at each end of the mission, a drone equipped with InDro Pilot can be controlled from across the country – with the pilot (and others) watching the data acquisition and all other aspects of any given mission in real-time.

 

Interface

 

InDro Pilot is an entire ecosystem for 4G and 5G drone operations, including complex missions involving LiDAR, thermal sensors – even winches. The user interface reflects that, with “modules” (ie winch, etc.) that can be added to customize for each mission. Here’s a look at just one of many modules, offering granular control and at-a-glance monitoring.

Canada Drones

“The InDro Pilot system is going to truly expand the capabilities of many Enterprise drones,” says InDro Robotics CEO Philip Reece. “Just as our InDro Commander module has made ground robots more powerful and customizable, InDro Pilot will do the same for UAVs.”

InDro Robotics has already delivered Wayfinder drones equipped with the InDro Pilot system to clients from the regulatory world. Commercial sales will commence shortly.

Interested in learning more? Feel free to contact Peter King.

InDro’s Take

 

As we said at the outset, nothing gets us revved up quite like creating new solutions. InDro Pilot has a myriad of powerful capabilities not outlined in this story – including some features that will definitely contribute to the safety of Beyond Visual Line of Sight flights though a proprietary system that will alert nearby private aircraft to the drone’s proximity during missions. So we’re excited about this product, much in the same way we were excited when we released InDro Commander for ground robots.

And while all Indro Robotics developments are team efforts, there’s often an individual who really takes the lead and owns the project. In this case, Ahmad Tamimi truly took charge, often working on it alone during those dark and early days of the global pandemic. InDro Pilot is a huge accomplishment, and we applaud Ahmad and the rest of the InDro team.

#CANSEC2022 – a wrap on the biggest security and defence show in Canada

#CANSEC2022 – a wrap on the biggest security and defence show in Canada

By Scott Simmie, InDro Robotics

 

The biggest annual security and defence conference in Canada – CANSEC – is a wrap. Put on by the Canadian Association of Defence and Security Industries, the trade show is like a Who’s Who of the vast supply chain necessary to keep Canada’s armed forces equipped.

That means everything from the pointy end of the stick (weaponry) through to advanced SCUBA gear, survival suits, radar units, flight simulators and more. Major companies like Lockheed Martin, L3Harris, QINETIQ, Google, Microsoft and others were among the 306 defence and security exhibitors that filled some 150,000 square feet on the trade floor.

It was clear (if it wasn’t before) that digital technologies play a huge role on the modern battlefield. Plus, there was a lot of hardware like this:

 

 CANSEC

There was also this guy, who spent his time in icy-cold water intended to show off the capabilities of the company’s survival suit. See that glove on the right? People attending the show were invited to plunge their hands in that frigid water with and without the glove on.

Trust us on this, it’s more comfortable with the glove.

CANSEC

Weaponized drone

 

On the drone front, there was a significant development. Norwegian drone maker GRIFF Aviation, known for its heavy-lift Enterprise drones, was displaying a variant of one of its models. In conjunction with Norwegian munitions manufacturer and defence firm Nammo, the two companies have outfitted the GRIFF 135 (payload capacity 30kg) to fire anti-tank rockets. This was the first time this machine has been publicly displayed.

CANSEC

And here’s a look at the business end of things:

CANSEC

Ukraine influence?

 

There has been a huge demand for drones since the Russian invasion of Ukraine. But that conflict played no role in the development of this machine.

“This is not something we came up with because of Ukraine,” says Geir Furø, GRIFF Aviation’s VP of Sales and Business Development.

“It’s been in the planning for the last four or five years. Only in the last year has it been coming together. So this will have a live-fire test later this fall. We hope to be manufacturing by early next year.”

 While InDro Robotics does not weaponize its drones or robots, we can certainly see the business case for GRIFF Aviation. What we found most interesting about this development is that drone manufacturers have typically followed either an Enterprise/Consumer track, or else a military one. In general, companies that are defence contractors (such as Aerovironment) don’t produce Enterprise/Consumer drones, and vice-versa. 

Furø said there had been a lot of interest in the product. It will be interesting to see whether this crossover leads other Enterprise manufacturers to consider adapting their products for a combat setting.

Submersibles

A couple of other displays caught our eye, as well. In the case we’re about to explore, Canadian companies that build submersible devices. These are tethered systems that, in general, send back high-quality real-time video and other data to the surface (they can be equipped with multiple sensors). Use-case scenarios include hull inspection, sediment sampling, and even retrieval of objects on the ocean bed. First Responders also use these devices when attempting to locate human remains following drownings, boat sinkings etc., keeping divers out of harm’s way.

Two different Canadian companies had displays at the CANSEC show, both offering submersible solutions.

MarineNav

 

Established in 2005, the company is based in Prince Edward Island – which has some obvious advantages when it comes to R&D and testing its products. It builds underwater Remote Operated Vehicles (ROVs), marine-grade computers, displays etc. Its Oceanus series has been deployed in use-cases ranging from border security and environmental assessment through to scientific research. MarineNav ROVs are built on-site, using rugged plastics and marine-grade anodized aluminum.

Its three models use thrust vectoring for positioning and can carry out unlimited mission times, since power is supplied via tether.

OceanUS

Range

 

The Oceanus Pro, seen above, has a depth rating of 305m (1000′). It’s controlled from the surface using a joystick and touch-sensitive topside monitor. That monitor has 1600 nits of brightness, meaning it’s easy to view even in bright daylight. The company’s Oceanus Ultimate has the same depth rating, but with an optional upgrade can descend to 500m (1640′).

We had the opportunity to chat with MarineNav staff and were impressed with both their commitment to quality, as well as the fact their line is manufactured from the ground-up, in-house.

 

Deep Trekker

 

The other company that caught our attention was Deep Trekker, based in Kitchener, Ontario. Deep Trekker has been around for a decade, and produces not only submersibles but also waterproof crawlers, designed for pipe inspections – even a vacuum robot that can clean sediment and sludge from the bottoms of reservoirs and tanks.

When we were recently at the AUVSI conference, we had an opportunity to operate its DTG3, a highly maneuverable and affordable ROV rated for up to 200m. Impressive, and just one of many machines for specific use-case scenarios.

Deep Trekker

In fact, Deep Trekker offers not only a broad range of products, but – not unlike drones – the option for additional sensors suitable to tasks such as Side Scan Sonar, water sampling, and even Non-Destructive Testing (NDT) tools.

 

InDro on the floor

We’d be remiss if we didn’t mention that InDro Robotics also had a presence at the show. That’s our own Peter King on the right, taking part in a demonstration with partners Microsoft Canada.

Peter was remotely operating our Sentinel robot, equipped with the InDro Commander system, over a 5G network. This was on day two of the conference (you’ll see Sentinel below). The previous day, we piloted a drone from the CANSEC show, with the drone many kilometres away at our Area X.O R&D hub.

InDro is a leader in teleoperating drones and robots over 4G and 5G networks, allowing for remote operations from around the block or across the country.

The operator monitors the mission via a web-based browser, seeing data in real-time as the mission unfolds.

Peter is a pro at this, as well as understanding the many use-cases that can benefit from such technology. For example, InDro Robotics can remotely inspect a solar farm to see if there are any malfunctioning panels. Having a human inspect those panels can literally take days, while generally a single drone flight of less than 30 minutes can usually detect any anomalies.

Interested? You can always reach Peter here.

CANSEC
CANSEC

InDro’s Take

 

Conferences are a great opportunity to gain a better understanding of a particular sector, as well as a chance to see what other companies are up to in that space.

We had conversations with many companies at CANSEC and were particularly impressed with several Canadian SMEs. Deep Trekker and MarineNav have both developed very impressive products, and – as a fellow R&D company – we applaud Canadian success stories that push the boundaries of engineering. Well done.

YOW drone detection program featured in WINGS magazine

YOW drone detection program featured in WINGS magazine

The Drone Detection Pilot Project being carried out at the Ottawa International Airport has received some traction in WINGS Magazine, Canada’s leading online and print publication about the aviation world.

InDro Robotics is one of the partners in the project at YOW, supplying hardware and software used to detect drones that might pose a threat to passenger, private and cargo aircraft using the airport. The program has gathered a lot of valuable data since it began in the fall of 2019.

But what it gathered during the anti-vaccine mandate protests in Ottawa in February of 2022 really raised some eyebrows. Drones were detected flying in a restricted flight zone over Parliament Hill and elsewhere in the downtown Ottawa core, with a spike during police operations to clear the protests.

A total of 27 different drones carried out 59 flights over a period of four days. Of those, 25 flights exceeded 400’ above ground level (Transport Canada’s limit, except in special circumstances). Eleven flights took place during hours of darkness – though that’s not a violation of regulations providing the drone is using lights that allow the pilot to maintain Visual Line of Sight and orientation.

Nonetheless, these flights all took place in restricted airspace. A small number were carried out by law enforcement, but the vast majority were not. As you’ll see in the following graphic, 15 unique drone IDs were detected, and 25 of the 59 flights were carried out above 400 feet (including one at 1583′ AGL).

Drone Detection

Wake-up call

 

Our initial story about this caused quite a stir, including this article in the Ottawa Citizen – along with attention from Canadian airports that do not currently have drone detection programs. And now, WINGS Magazine has picked it up.

The article appears in the May/June Digital Edition, which is also a print edition.

Drone detection

Drone detection, made simple

 

The system in place at YOW includes a micro-Doppler radar, capable of detecting the movement of small drone propellors at close range. It also features a sophisticated antennae array, which has been picking up flights as far as 40-50 kilometres from the airport.

The system is automated – and the data is banked. If a drone poses an immediate threat to a flight path, an alert is sounded and airport authorities can quickly respond.

You can read the story that appears in WINGS Magazine here. We’d also like to thank editor Jon Robinson for picking this up.

InDro’s take

 

We’ve pleased to be an integral part of the YOW Drone Detection Pilot Project. The results have been greater than we all anticipated, with highly granular data that has helped YOW educate drone pilots and also prepare an airport protocol for those rare but critical occasions when RPAS flights have the potential to impinge on the safety of crewed aircraft. The system provides enough advance warning that aircraft pilots can be given a heads-up and instructions to minimise any conflict with drones; the system is also capable of identifying the location of the RPAS pilot.

Monthly data is shared with program partners and has generated interest from other Canadian airports. The data detected during the Ottawa protests has also attracted the interest of those responsible for the safety of Parliament Hill and other critical buildings in the downtown Ottawa core.
