Flying a drone in dense urban settings comes with its own set of challenges.

In addition to following regulations laid out in the Canadian Aviation Regulations (CARs) Part IX, operators have to contend with other factors. Helicopters, for example, routinely share urban airspace. And, in addition to surrounding buildings, streets are generally more densely packed with people and vehicles than other locations.

But there’s another factor that can really cause problems: Wind.

Airflow in urban centres is very different from rural settings. The close proximity of multiple buildings can amplify wind speed and create tricky – and invisible – areas of turbulence. These can cause havoc for operators, and potentially for people and property on the ground.

That’s why the National Research Council, in conjunction with Transport Canada and other partners, is conducting research on urban airflow.

WHY THE RESEARCH?

 

The National Research Council is helping to prepare for the future of Urban Air Mobility. That’s the coming world where intra-urban drone flights are routine – and where airspace is seamlessly shared with traditional crewed aircraft. As the NRC states on this page:

“The vertical take-off and landing capability of UAS promises to transform mobility by alleviating congestion in our cities.”

As part of its seven-year Integrated Aerial Mobility program (launched in 2019), the NRC has already been working on developing related technologies, including:

  • “optical sensor-based detect-and-avoid technologies to assist path planning of autonomous vehicles
  • “drone docking technologies to support contact-based aerial robotics tasks
  • “manufacturing of high-density and safe ceramic lithium batteries to enable low-emission hybrid-electric propulsion”

The NRC is also interested in wind. Very interested.

 

DRONE FLIGHTS IN URBAN CENTRES

 

Drone delivery – particularly for medical supplies and other critical goods – will be part of this world before long (home deliveries will likely come eventually, but not for some time). In the not-so-distant future, it’s likely that specific air corridors will be set aside for RPAS traffic. It’s also likely, eventually, that an automated system will oversee both drone and crewed aircraft flights to ensure safety.

Part of the path to that future involves looking at the unique characteristics of urban wind patterns – along with the potential challenges they pose to drone flights. Are there certain locations where increased wind speed and turbulence pose a greater risk to safe RPAS operations? What wind speeds might be deemed unsafe? Can data gathered help lead to guidelines, or even additional regulations, for operations in cities? If the speed of wind at ground level is X, might we be able to predict peak turbulence wind speeds? Might drone manufacturers have to revise their own guidelines/parameters to take these conditions into account?

Those are the questions that interest the National Research Council, in conjunction with Transport Canada and other partners. And InDro Robotics is helping to find the answers.

RESEARCH

 

Previous studies have shown that turbulence caused by buildings can indeed impact the stability of RPAS flights. Now, the NRC is keen on digging deeper and gathering more data.

The research is being carried out by NRC’s Aerospace Research Centre, in conjunction with a number of partners – including McGill University, Montreal General Hospital, CHUM Centre Hospital, InDro Robotics and others. The flights are being carried out by InDro’s Flight Operations Lead, Dr. Eric Saczuk (who is also head of RPAS Operations at the BC Institute of Technology).

Urban environments create a variety of exacerbated micro-level wind effects including shear, turbulence and eddies around buildings. These effects can locally increase reported wind speeds by up to 50 per cent,” says Dr. Saczuk.

InDro has been involved with this research for three years – with earlier flights carried out in the NRC’s wind tunnel. Now, the testing has become more real-world. InDro flies a specially equipped DJI M300. The wishbone-shaped appendage in the photo above carries two tiny anemometers placed specifically to capture windspeed and variations without being affected by the thrust generated by the rotors. The drone is also equipped with an AVSS parachute, since these flights take place over people.

 

THE MISSIONS

 

Some months prior to the flights, the NRC installed fixed anemometers on the roofs of the hospitals mentioned above. This allowed researchers to obtain a baseline of typical wind speeds in these areas. Then came the flights.

Part of our mission is to fly the drone over three different rooftops and lower the drone to hover at 60m and 10m above the anemometer station,” says Dr. Saczuk.

“This allows NRC to compare the wind data recorded by the static anemometers with data captured by the mobile anemometers on the drone. Our launch sites are from the CHUM Centre Hospital and the Montreal General Hospital, which are about three kilometres apart with a pilot at each location. Additionally, we’ll be flying the drone from one hospital to the other and also along an ‘urban canyon’ between the three rooftops.”

CHALLENGES

 

Flying in urban locations always requires additional caution. The research also demands very precise altitudes while capturing data – along with piloting with the anemometers attached to the drone.

Gathering the data always has its challenges – especially when operating over a dense downtown core such as Montreal,” he says.

“Many months of planning led to two days of successful data capture on July 26 and 27. One of the main challenges is maintaining C2 connectivity amongst the tall buildings. Another consideration is ensuring a proper center of balance with the added payload well forward of the aircraft. Resultingly, flight endurance is shortened due to the extra load on the motors and thus we had to modify our flight plans to account for this. We learned a lot during the first two days of data capture!”

For Dr. Saczuk, this is a particularly rewarding research project. Why?

Quite simply because it’s cutting-edge and involves RPAS,” he says.

“We have established a great relationship with the test facility at NRC and Transport Canada, so to know that InDro is involved in helping to understand the potentially adverse effects of flying RPAS around tall buildings for the purpose of making these flights safer feels very rewarding. Personally, I also enjoy challenging missions – and this may well be the most challenging mission I’ve ever flown!”

INDRO’S TAKE

 

InDro Robotics has a long history of involvement with research projects and other partnerships with academia. We are particularly drawn to projects that might have a positive and lasting impact on the industry-at-large, such as this one.

“Urban wind tunnels and turbulence have the potential to disrupt even a well-planned RPAS mission,” says InDro CEO Philip Reece. 

“As we move toward more routine drone flights in urban centres, it’s important to capture solid data so that evidence-based decisions can be made and Best Practices evolve. This research will prove valuable to the Canadian RPAS industry – by helping to ensure safer urban drone operations.”

The research is ongoing; we’ll provide updates when further milestones are hit.

InDro Robotics tapped to fly drone missions at Kelowna fire

InDro Robotics tapped to fly drone missions at Kelowna fire

By Scott Simmie

 

As forest fires continue to threaten Kelowna, BC, officials have urged tens of thousands of residents to heed warnings and evacuate from the area. Some 30,000 people are currently under an evacuation order, with another 36,000 being told to stand by and be ready to flee if necessary.

“We cannot stress strongly enough how critical it is to follow evacuation orders when they are issued,” said BC minister of Emergency Management Bowinn Ma on Saturday. “They are a matter of life and death not only for the people in those properties, but also for the first responders who will often go back to try to implore people to leave.”

Now, the City of Kelowna has called on InDro Robotics to assist with the effort by flying drone missions to gather specific data.

Recent footage shows just how close the fire is to the city:

INDRO TO ASSIST

 

On Friday, InDro Robotics was approached by the City of Kelowna to assist in damage assessment by flying drones in the affected areas and also to carry out thermal missions. The first flights are being deployed today (Monday, August 21, 2023).

InDro is carrying out thermal missions over the city landfill, which is burning beneath the surface. A FLIR sensor will identify hot spots for those involved with fire management.

“With a rapidly changing situation, decision-makers need the best available data,” explains InDro CEO Philip Reece. “The thermal data will be useful – as these subterranean fires, which can smoulder for days and even weeks, are not visible to the naked eye.”

In addition, InDro will be flying missions to assess damage and pull together high-resolution photogrammetry. Plans are to use the Spexigon platform for those missions.

 

SPEXIGON

 

The Spexigon platform simplifies the acquisition and processing of high-resolution earth imagery using most popular drones.

The software standardises the capture to produce imagery at scale. The process begins with Spexigon capturing and indexing raw drone imagery. That imagery can then be used by the SpexiGeo software (or other third-party platforms).  The imagery below was captured by Spexigon, but processed and viewed on the SpexiGeo app (you can scroll through the imagery and zoom in, revealing the high resolution).

AUTOMATED

 

Spexigon automates the flights; the pilot’s job is simply to monitor the airspace like a visual observer (though manual control can be taken over at any time). This automation results in greater accuracy when capturing data over targets of interest and produces a database that can easily and securely be accessed by decision-makers.

The Spexi app provides access to multiple features, including:

  • Planning tools for efficient and accurate data acquisition
  • Autonomous flight using the latest DJI drones
  • Secure, cloud-based footage processing and sharing
  • Survey work using Ground Control Points

“Obtaining high-resolution photogrammetry requires precise flying – including maintaining a consistent height above ground level,” says Reece. “The automated flights will ensure consistent photos – which will provide decision-makers with a clear picture of what’s been damaged, and to what extent.”

 

WILDFIRE “TOURISTS”

 

The spectacle of this raging fire has, unfortunately, drawn some unwanted attention. Officials say unauthorized drones flights have been taking place with people posting video to social media. The presence of drones not directly related to emergency operations is both illegal and dangerous. Water bombers and helicopters are in regular use and drones can pose a threat to those operations.

“Drones are a significant hazard to our air crews fighting fires,” said Bruce Ralson, BC’s Minister of Forests, on Saturday. “Now is not the time to take the footage or photos of active wildfires. Not only is it irresponsible, but it is illegal to fly them in fire areas.”

InDro is working closely with Kelowna emergency operations to ensure any drone flights do not pose a conflict with crewed aviation.

“This will be an ongoing operation and we’ll obviously be taking great care to ensure any InDro-operated flights are well clear of other aerial firefighting operations,” says Reece (pictured below).

InDro Robotics

INDRO’S TAKE

 

The wildfires near Kelowna – and Yellowknife – are obviously of serious concern. InDro hopes to make a meaningful contribution to those involved in the emergency response.

“Drone-gathered data – whether thermal or visual – helps those in charge make the best possible decisions in a rapidly changing situation,” says InDro’s Reece. “We will fly missions as long as required, and offer any other assistance we can. We hope the situation for the tens of thousands of people impacted by this disaster returns to normal as soon as possible.”

We’ll provide further updates as missions progress.

Update: Following the completion of our missions, the City of Kelowna provided the following statement.

“The Regional District of the Central Okanagan Emergency Operations Center contracted InDro Robotics to capture drone footage of the Clifton-McKinley fire area.  Flights were coordinated and authorized through the Emergency Operations Center.

“The thermal imagery captured by drones improved firefighting by providing precise data on underlying fire threats. Marking specific hotspots on maps where the ground temperature exceeded safe levels allowed responders to pinpoint exactly where fires were burning underground, ensuring a more effective and targeted response. In addition, the footage allowed Emergency Operations Center staff to share imagery with directly impacted property owners, allowing them to understand the magnitude of the damage before it was safe to allow re-entry.”

Smart Mobility companies invited to TCXpo 2023

Smart Mobility companies invited to TCXpo 2023

By Scott Simmie

 

We’re already excited. And we’ve blocked off September 27, 2023 in the InDro calendar.

Why’s that? It’s because that’s the day of the second TCXpo – a demo day and networking event featuring Canadian companies in the Smart Mobility space – will take place. The inaugural TCXpo, which took place at Area X.O in Ottawa, was amazing. And the second one will be even bigger and better.

The event is the only one of its kind in Canada. And it brings together cutting-edge companies with Connected and Autonomous Vehicles (ground robots, drones, cars) and related technologies. This year, more than 70 companies will demonstrate their products to the industry, investors, and government agencies in this space. 

Below: Some of the fun from the inaugural TCXpo in 2022:

Canada Robotics

A CANADIAN SHOWCASE

 

The goal of TCXpo is to demonstrate Smart Mobility technology. And Area X.O is the perfect venue. The R&D complex, operated by Invest Ottawa, is a private facility. It has its own Smart City infrastructure, including a dedicated 5G network. There are roads, traffic lights, railroad crossings – most of the things you’d find in an urban environment – except this site is dedicated for robots, drones and other Connected Autonomous Vehicles (CAVs). 

Now, picture a drone dropping a payload attached to a steerable parachute that can land within metres of the desired target. Envision an autonomous car, braking when a mock pedestrian appears before its path. Or a completely amphibious robot, capable of operating in water, on ice and snow, doing its thing for spectators.

All of these happened in 2022. And there will be even more at this year’s event.

“TCXpo is a tremendous opportunity for Canadian companies to showcase their products,” says InDro Robotics CEO Philip Reece (who was the person in charge of all aerial operations at the 2022 event). “This is such a forward-looking event. Many of the products shown here will play a role in the Smart City of the future.”

The event is put on by Invest Ottawa, Transport Canada, FedDev Ontario, Innovation, Science and Economic Development Canada (ISED), as well as other event sponsors (including InDro Robotics, one of the lead private contributors). 

And for Small and Medium-sized Enterprises (SMEs), it’s a major opportunity. Here’s how Area X.O describes what to expect:

“TCXpo will create an exclusive opportunity for invited guests to experience the power and impact of cutting-edge Canadian technologies, including many preparing for global markets. Companies large and small from Canada’s capital and across the country will showcase connected and autonomous vehicles, drones, smart-city solutions, IoT (Internet of Things), robotic technology, agri-tech innovations, and more. The showcased applications will span every sector of our economy – from intelligent transportation to defence, public safety, smart farming, telecommunications, cleantech, environment, and smart cities.”

Below: InDro Robotics CEO Philip Reece speaking at the 2022 event

HOW MUCH DOES IT COST?

 

Interested in getting your Smart Mobility product or service in front of the people and companies that count? Looking for investment? TCXpo is the place.

And the good news? Unlike expensive trade shows, those companies accepted can set up a display for free. (And while there’s truly no such thing as a free lunch, some really great food trucks showed up last year to feed the nearly 900 people who registered.)

 

GREAT! HOW DO I GET INVOLVED?

 

So glad you asked. First of all, have a good read about the event – including some metrics on attendance, media coverage and more – right here. If you think your company is a fit, head right over to the Area X.O intake form and let them know you’re interested. The deadline for applications is August 18.

It’s also worth noting that TCXpo takes place during Smart Mobility week in Ottawa. There are numerous other events, including the country’s premier Smart Mobility Conference – CAV Canada – taking place the same week.

Below: Check out highlights from TCXpo 2022

INDRO’S TAKE

 

We’re obviously big fans of TCXpo – and a key corporate sponsor. But there’s another reason we’re particularly excited about the 2023 event.

“The new Drone and Advanced Robot Training and Testing facility – which we call DARTT – officially opened in June,” says InDro CEO Philip Reece. “This will enable some truly great demonstrations of ground robots navigating challenging obstacles, as well as the ability to showcase new drone technologies within a safe netted enclosure.”

InDro – and all of our many robots and drones – will be at TCXpo 2023. We hope to see you there, as well!

Canadian Startup KiDrone has big plans – and technology – for reforestation

Canadian Startup KiDrone has big plans – and technology – for reforestation

By Scott Simmie

 

A Canadian startup has ambitious plans to deploy long-range, high-payload drones for reforestation at scale.

Using an extended-range, heavy-lift drone and patent-pending Machine Learning, the company calculates it could drop one million seeds in a single mission. Not only that, but it could plant seeds for different species in the most appropriate locations.

“We are a reforestation technology company,” explains CEO and Founder Trevor Grant. “We are going to be deploying heavy-lift unmanned helicopters coupled with AI machine learning to scale reforestation to industrial levels.”

That’s an impressive goal. Let’s look at how KiDrone plans to achieve it.

 

GENESIS

 

Many of the startups we’ve met over the years were founded by engineers. But CEO/Founder Trevor Grant is a lawyer by trade. So how did he wind up starting a venture involving drones and reforestation? Well, a couple of things happened.

First, he happened to watch a documentary on Netflix called Breaking Boundaries: The Science of Our Planet. It was about climate change, and the need to take urgent action on a global level. The following day, he happened to be reading an article about Beyond Visual Line of Sight flights. And then he started thinking.

“It tweaked in my head, perhaps the largest impediment to this (reforestation) is labour supply. And fleets of autonomous drones might be able to tackle such a problem at scale,” says Grant. Plus, he was also thinking about his children, living during an unprecedented era for planet earth.

“There was a genuine desire to leave the world to my kids better off than it was left to me,” he said during an interview at Toronto’s Collision conference.

And so KiDrone was soon born, with a mission to drop enough seeds to truly make a difference. But not just haphazardly. To ensure the best results, seeding would need to be targeted – with the correct species dropped in locations best suited to their survival and the broader ecosystem. Plus, the seeds would need to be coated.

“Seed encapsulation technology has been around for a very long time, but mainly in the agricultural sphere, not much for the reforestation or restorations sphere,” explains Fatima Mahmud, KiDrone’s Chief Scientific Officer. Mahmud is an environmental scientist born in the Middle East and who studied at the University of California, Berkeley, before obtaining her Masters degree in Toronto.

“Some of the reasons for encapsulating a seed, for aerial seeding specifically, is number one: It increases the flowability of the seed through the (dispersal) mechanism. Number two: It adds weight to the seed so the seed drops to the site. You can also add materials or compounds to the encapsulation that can deter pests and predators. And making the seed uniform allows it to find a suitable microsite in the soil once it’s dispursed.”

Below: Encapsulated seeds at KiDrone’s Collision display

GETTING STARTED

 

Going from an idea to a viable product or service is a voyage – just ask any Startup. And the first part of KiDrone’s path has been to demonstrate that this is a viable, doable solution.

“It’s been a two-year journey to validate our hypothesis and validate where direct seedings works and where it doesn’t work,” explains CEO Grant. “Because direct seeding isn’t a cure-all for all reforestation needs. It’s highly effective in many situations – but not all.”

Post-wildfires (and Canada has had many this year), is a very promising use-case. Grant says high-intensity fires can consume the natural seed inventory that might be on the forest floor.

“So there’s a need for direct seeding at that point. Where direct seeding struggles is in drought-prone conditions,” he says.

 

TARGETED SEEDING USING AI

 

It’s not that difficult to deliver seeds via a drone. In fact, some companies have been dropping seeds and seed pods successfully. What differentiates KiDrone is its planned use of AI – and a proprietary seed dispenser capable of holding the seeds of 12 different species and disbursing them selectively. By examining multiple data points during flight, the drone will autonomously dispense the seeds best suited to particular locations based on the mission profile.

“There’s thousands of data points for any given site – climactic, GIS, various forms of imagery or LiDAR, soil lab results – an endless amount of data you can get to classify or gain conditions on a site,” explains Grant.

“And that will all lead to whether certain species may or may not be optimal (for a specific location), and what other species might be supportive. Our AI will be able to determine which trees are more likely to succeed in which areas. Because we’re not interested in monoculture or pine nurseries. We’re very interested in a more holistic reforestation approach that includes many different species, supported species, and Indigenous species of medicinal worth and spiritual worth.”

That last part is very important to KiDrone.

“Our biggest commitment is to work alongside the Indigenous communities where we operate. It’s their land and it’s their traditional territory. They should be the ones directing how reforestation happens. We simply view our roles as facilitating the reforestation goals that they have.”

Below: Founder/CEO Trevor Grant at the Collision conference.

 

KiDrone

THE NUTS AND BOLTS

 

It’s clear, speaking with CEO Grant, the company is working toward its goal via a methodical, evidence-driven trajectory. There’s been a lot of work on seed encapsulation so far though a partnership with the Northern Alberta Institute of Technology (NAIT), as well as a flight using a crewed helicopter for dropping encapsulated seeds. It successfully seeded 40 hectares.

“Our largest concern is validating where the seeds will grow, not where the drone will fly,” he says. “We’re concerned about the science behind encapsulation and determining where it’s effective to seed and where it’s not. We’re putting the science first, because we’re looking to do this for the next 20 years and not simply flip a carbon offset project.”

Existing startups doing seeding tend to use multi-rotor designs, which limits the distance they can cover per mission. Here, KiDrone differentiates itself by planning to use a much longer-range drone. The company has established a relationship with Scheibel, a manufacturer of UAVs (and landmine detectors). The company has a long-range uncrewed helicopter called the S-100. It can carry 50 kilograms of payload (seeds plus dispersal mechanism), and has an incredible range – up to 1000 kilometres, says Grant.

“The great thing about having such a large airframe that we’re looking to deploy – we’re able to carry 12 different species in one flight,” he says.

“So mid-flight, while travelling at 100 kilometres an hour, the system will be able to disperse an entirely different species, change the ratio of species being disbursed, add different nitrogen fixers or supportive species, all autonomously, based on AI and a seed-planting pattern that is pre-loaded to the mission.”

KiDrone

THE BUSINESS CASE

 

There can be no question there’s an environmental demand for reforestation at scale. KiDrone’s pitch deck states “Reforestation in Canada is broken.

“Since 2010, Canadians have lost more than 44 million hectares of tree cover due to timber harvesting, wildfires, and commercial development. This represents an urgent, unmet need and opportunity to radically transform how industry & government deliver and scale reforestation in Canada.”

And with the devastating and deadly wildfires of 2023, the country has lost even more of that tree cover. The current system, of using human beings to plant seedlings, simply cannot keep up with the demand. It’s also inefficient – and there are vast tracts of forest in Canada that are simply inaccessible.

The big forestry companies also tend to have reforestation deficits, where they simply have not been able to reforest at a rate equal to the harvesting of timber. Plus, the KiDrone deck points out, “Corporate Canada’s demand for carbon offset opportunities vastly outweigh the current supply.”

So there’s not only an environmental imperative, but there’s also a strong business case. The company has been targeting three different sectors:

  • Top 12 Canadian forestry companies, each with reforestation requirements > 25k hectares
  • Federal & provincial forestry departments “focused on post-wildfire timber supply mitigation”
  • Carbon credit offset buyers and sellers

It all equals huge demand for a service like this, says Grant.

“Endless,” he says. “I think the wildfires we’ve had to date are a good example of of how large the reforestation required is in Canada alone – let alone globally.”

The company’s business model projects dropping 10k seeds per hectare in the future, with a 20 per cent viability rate. That comes out to 2,000 trees per hectare, at $.50 per tree. That’s $1,000 per hectare. Based on operating one drone and starting operations in 2024, its revenue projections climb to more than $1.2M by 2026 – and that’s with a single drone deployed. And because costs are low when compared with traditional tree seeding/planting methods, nearly all of that revenue would be profit.

The company is currently in a seed round (and we’re talking capital here, not trees), which its hoping to close late this summer or early fall. Once complete, there will be some additional immediate hires and KiDrone will be in “an early operational state.”

Grant is aware that BVLOS permission won’t be automatic, so he anticipates some of the early deployments will be VLOS, or operating with specific SFOCs.

INDRO’S TAKE

 

We’ve been through the Startup path, and know of the many challenges that come with the territory. But we also know a good idea when we see it. KiDrone has clearly identified its market and has laid out a solid path to commercialisation. It’s also a perfect application of autonomous technology for the Three Ds – taking on jobs that are dirty, dull and dangerous.

“In an era of climate change and with record-setting temperatures, getting more trees on the planet at scale helps all of us. I see this as definitely a Drones For Good application,” says Indro Robotics CEO Philip Reece. “I also really like seeing that KiDrone is taking it slow with an evidence-based approach – and a solid business plan. I look forward to hearing about their first deployment.”

Boston University uses AgileX LIMO for research

Boston University uses AgileX LIMO for research

By Scott Simmie

 

What will the Smart Cities of the future look like?

More specifically, how will the many anticipated devices operate – and cooperate – in this coming world? How will connected and autonomous vehicles interact to ensure the greatest efficiency with minimal risk? How might ground robots and drones fit into this scheme? And how can researchers even test algorithms without a fleet of connected vehicles, which would obviously incur great costs and require huge testing areas?

In the case of Boston University, the answer is in a small but powerful robot called LIMO.

LIMO

A VERSATILE PLATFORM

 

We spoke with three engineers from Boston University, each of whom are working with the AgileX LIMO platform. Before we get into an overview of their research, it’s worth taking a look at LIMO itself. Here’s how the manufacturer describes the product:

“LIMO is an innovative multi-modal, compact, and customizable mobile robot with Al modules and open-source ROS (Robot Operating System) packages, which enables education, researchers, enthusiasts to program and develop Al robots easier. The LIMO has four steering modes including Omni-directional steering, tracked steering, Ackerman and four-wheel differential, in line with strong perception sensors and Nvidia Jetson Nano, making it a better platform to develop more indoor and outdoor industrial applications while learning ROS.”

And it all comes in a pretty compact package:

 

LIMO

CAPABLE

 

While its user-friendly design is suitable for even enthusiasts and students to operate, its sophisticated capabilities mean it’s also perfect for high-end research. (You can find full specs on the product here.)

LIMO can detect objects in its surroundings and avoid them, and is even capable of Simultaneous Localisation and Mapping (SLAM). With a runtime of 40 minutes, extended missions are possible.

Here’s a look at LIMO in action, which provides a pretty good overview of its capabilities:

HIGH-LEVEL RESEARCH

 

We spoke with three people from Boston University, each of whom are using LIMO for different purposes. The three are:

  • Christos Cassandras, Distinguished Professor of Engineering, Head of the Division of Systems Engineering, and Professor of Electrical and Computer Engineering
  • Alyssa Pierson, Assistant Professor, Department of Mechanical Engineering
  • Mela Coffey, Graduate Research Assistant and PhD candidate under Alyssa Pierson in Mechanical Engineering

Cassandras is focused on groups of robots working cooperatively (and sometimes uncooperatively), called Multi-Agent Systems. If you think ahead to a connected Smart City of the future, the cars on the road would be Connected Automated Vehicles (CAVs). They would all be aware of each other and make autonomous decisions that ensure both safety and efficiency. Far enough down the road, today’s traffic signals, stop signs and more would likely not be needed because the vehicles are collectively part of a network.

“These vehicles become nodes in an Internet in which the vehicles talk to each other,” says Cassandras.

“They exchange information and so, ideally cooperatively, they can improve metrics of congestion, of energy, of pollution, of comfort, of safety – perhaps safety being predominant.”

In the video below, you’ll see LIMOs driving cooperatively, calculating in real-time the most efficient way to merge:

 

MAKING THE TRANSITION

 

But as we head toward this future, there will be a blend of regular cars and autonomous vehicles until the transition to automated driving is complete. And that period of transition will create its own challenges, which also interest Cassandras.

“So typically what we expect within the next, let’s say five to 10 years, is a mixture of the smart connected autonomous vehicles and the regular vehicles that we typically refer to as Human Driven Vehicles or HDVs. So the idea is: How can we get these teams of autonomous agents to work together?”

Obviously, testing this in a real-world scenario – with a blend of autonomous and HDVs – would be hugely expensive and require closed roads, etc. Enter LIMO – or, more accurately, a fleet of LIMOs.

“Since I can’t use dozens of real vehicles, I would like to use dozens of small robots that can be thought of as these autonomous vehicles, (which can) talk to each other, cooperate,” he says. “But also sometimes they don’t really cooperate if some of them are the HDVs. So what we are doing in our Boston University Robotics Lab, of which Alyssa and I are members along with several other colleagues, is we deploy these LIMOs that we have acquired as teams of autonomous vehicles.”

And what kinds of scenarios are they looking at? Well, consider how things work now. Cars stop at red lights, idle, and then quickly accelerate when the light turns green. This is hugely inefficient and adds to pollution. Wouldn’t it be better if there were no traffic lights at all, and vehicles could safely navigate around one another at peak efficiency? Well, of course. And that’s the kind of work Cassandras is conducting with a fleet of LIMOs at the Boston University Robotics Lab.

He is also one of the authors of a scientific paper that will be presented at the 7th IEEE Conference on Control Technology and Applications (CCTA) in August. That paper is entitled: “Optimal Control of Connected Automated Vehicles with Event-Triggered Control Barrier Functions: a Test Bed for Safe Optimal Merging.”

RASTIC

This fall, Boston University will open a new facility called the Robotics & Autonomous Systems Teaching & Innovation Center (RASTIC). There will be an area dedicated to mimicking a Smart City, with large numbers of LIMOs driving cooperatively (and sometimes uncooperatively). Cassandras says he intends to use a ceiling-based projector to create a simulated network of roads and obstacles on the floor for LIMOs to navigate.

“I envision about 20 to 30 LIMOs moving around, communicating – trying to get from Point A to Point B without hitting each other, as fast as possible, making turns, stopping at traffic lights if there are traffic lights, and so on… That’s the the grand vision. And RASTIC is intended for teaching as opposed to research.”

Other research using LIMOs will continue, meanwhile, at the existing Boston University Robotics Lab.

The following video, and this link, help explain RASTIC – and why this will be a significant facility for the Engineering Department.

THE IOT

 

So that’s one part of the resesarch using LIMOs. But wait, there’s more!

Assistant Professor Alyssa Pierson is also interested in Multi Agent Systems. But her work focusses less on the autonomous vehicle side of things, and more on general small-scale autonomous platforms. Think of delivery robots, drones, or even some other autonomous sensor platform making its way through the world.

“So thinking about instead of saying that two agents are inherently cooperative or non cooperative, what are all those nuanced interactions in between?” says Pierson.

“What does it mean if robots and a team have reputation that they can share among other robots? How does that change the underlying interactions? And we’re looking at these things, what reputation might mean, for instance, in perhaps robot delivery problems. How do they decide how to share resources, how to deliver supplies? The LIMOs provide a hardware platform to demonstrate these new algorithms that we propose.”

Graduate Research Assistant Mela Coffey is involved with this work, as well as some of her own as a PhD candidate.

THE HUMAN FACTOR

 

Both Coffey and Pierson are also interested in how humans play a role in this world. And, more specifically, how robots might gather data that could assist humans in their own decision-making while tele-operating robots. Perhaps the robots might suggest that the human operator choose a more efficient route, for example.

It’s serious research, and a scientific paper on it has just been accepted for the upcoming International Conference on Intelligent Robots and Systems, IROS.

Coffey says the LIMO is perfect for this kind of research because it offers a hassle-free platform.

“From the start, they’ve been super easy to set up,” she says. “It’s nice just being able to take the robots right out of the box and there’s very minimal setup that we have to do. As roboticists, we don’t want to focus on the hardware – we want to just put our algorithms on the robot and show that our algorithms can work in real-time on these robots.”

Boston University has purchased a significant fleet of LIMOs from InDro.

“I think roughly total is about 30,” says Cassandras. “One of the things I was unhappy about with other small robots that we’ve worked with is that they would break a lot. That’s to be expected – if you have 10 and a couple break after a few months, that’s OK. But if you have 10 and six break, that’s not good. The LIMOs have been very reliable.”

INDRO’S TAKE

 

Account Executive Luke Corbeth is the person who put these LIMOs into the hands of Boston University. He says it’s truly a perfect platform for such research.

Since LIMO is multi-modal, researchers can test their algorithms with a differential, Ackerman, omnidirectional or tracked system without needing to purchase 4 separate units,” he says. 

“The LIMO comes equipped with all the hardware needed for multi-robot teaming. It’s rare to find such a versatile and budget-friendly platform with the compute, connectivity, cameras and sensors that are needed to make this type of project possible.”

Corbeth deals with the majority of InDro clients – and is passionate about his work, and the work people like the Boston University team are doing.

I genuinely believe in a future where robots make our lives easier. My clients are the ones pushing us towards that future, so it’s satisfying to enable this sort of work. Above and beyond the research aspect, I know the students of my clients are learning a lot from using this robot, so it’s gratifying to know we’re assisting the next generation of innovators as well.”

And the best part? Priced at under $3000, LIMO is affordable, even for clients with limited budgets.

Drone pilot fined $3,021 for drone incursion at YOW

Drone pilot fined $3,021 for drone incursion at YOW

By Scott Simmie

 

A drone pilot has been hit with fines totalling more than $3,000 for two unauthorised and potentially dangerous flights at YOW – the Ottawa International Airport.

The flights took place in December of 2022 and involved the drone flying in close proximity to active runways while aircraft were landing. The flights were detected – and the pilot located – by the YOW Drone Detection Pilot Project. InDro Robotics supplies the core technology for that system, which has been in operation some 2-1/2 years.

In fact, the system allowed police to be directed to the location of the pilot while he was flying the drone from inside his car at a hotel parking lot.

“The individual was quite surprised that a police cruiser pulled up – and expressed ignorance about flying in the vicinity of the airport,” says Michael Beaudette, Vice President of Security, Emergency Management and Customer Transportation with the Ottawa International Airport Authority.

“He said he wasn’t aware he couldn’t fly there.”

He was about to be educated.

INTRUSION

 

The system at YOW is capable of detecting the location of active DJI drones up to 40 kilometres away. It is also designed to pick up on other brands of commercial drones flying at closer proximity to the airport by identifying their unique radio frequency signatures.

On December 20, the system generated an alert. Someone was flying a DJI Air 2S drone, which weighs 595 grams, adjacent to the airport.

Flight one: The flight began at 10:07 AM and the drone and pilot were detected at the parking lot of the World Fuel Services building. The drone remained at ground level for five minutes; at 10:12 the operator and drone were detected near the hotel immediately adjacent to the airport – a likely indicator the pilot was in a vehicle and on the move. The drone began increasing in altitude, reaching a height of 873′ – nearly 500′ above the altitude allowed by Transport Canada in areas where drones are permitted. The flight lasted nearly 17 minutes, during which a helicopter arrived at the airport.

Our Airport Operations Coordination Centre (AOCC) quickly checked to see if there had been any approvals granted for drone activity in the immediate vicinity of the airport and confirmed that there were none,” explains Beaudette. “They then notified the Airport Section of the Ottawa Police Service of the detection, who were then dispatched to the general area where the drone had been active. However, by that time the flight had been terminated.”

Flight two: The pilot was detected in the parking lot of the Fairfield Inn & Suites by Marriott Ottawa Airport. This flight began at 11:35, climbing initially to an altitude of 200′ before increasing to 507′ Above Ground Level. Lasting 6.85 minutes, the drone landed at 11:41. While that drone was in the air, a Jazz Q-400 landed on Runway 25 at 11:36.

 

“When we received an alert of the second flight, we were able to track the drone flight in real time and pinpoint the exact location of the pilot,” adds Beaudette. “The Ottawa Police Service cruiser approached the pilot as he was sitting in his car piloting the drone and ordered him to land it immediately.”

It’s no surprise these flights were of great concern to authorities at the airport.

Both flights took place without prior notification to, or approval by, NAV Canada,” says Beaudette. “The drone was operating within 350 meters of an active runway and during the first flight, the drone was also operating in very close proximity to a helicopter that was manoeuvering in the area.”

The image below, via Google Earth, shows where the system detected the pilot. During the second flight, police located the pilot mid-flight and ordered him to bring the drone to the ground.

KNOW THE REGS

 

As the saying goes, “Ignorance is no excuse for the law.” In other words, being unaware of regulations provides zero legal cover. Police took the pilot’s information, which was passed along to Transport Canada.

That’s because it’s TC, not local law enforcement (with the exception of local bylaw infractions), responsible for enforcing rules that govern drones. And in Canada, those rules are found in Canadian Aviation Regulations (CARS), Part IX. (If you’re a drone pilot and haven’t read these yet, we highly recommend you do.)

THE PENALTIES

The pilot violated multiple sections of CARS. And each of those comes with a financial penalty. Here are the sections violated, and the fines assessed:

  • CAR 900.06 – No person shall operate a remotely piloted aircraft system in such a reckless or negligent manner as to endanger or be likely to endanger aviation safety or the safety of any person. (Penalty assessed: $370.50)
  • CAR 901.02 No person shall operate a remotely piloted aircraft system unless the remotely piloted aircraft is registered in accordance with this Division. (Penalty assessed: $370.50)
  • CAR 901.14(1) Subject to subsection 901.71(1), no pilot shall operate a remotely piloted aircraft in controlled airspace(Penalty assessed: $456.00)
  • CAR 901.25(1) Subject to subsection (2), no pilot shall operate a remotely piloted aircraft at an altitude greater than (a) 400 feet (122 m) AGL; or (b) 100 feet (30 m) above any building or structure, if the aircraft is being operated at a distance of less than 200 feet (61 m), measured horizontally, from the building or structure. (Penalty assessed: $456.00)
  • CAR 901.27 No pilot shall operate a remotely piloted aircraft system unless, before commencing operations, they determine that the site for take-off, launch, landing or recovery is suitable for the proposed operation by conducting a site survey that takes into account the following factors:

      (a) the boundaries of the area of operation;

      (b) the type of airspace and the applicable regulatory requirements;

      (c) the altitudes and routes to be used on the approach to and departure from the area of operation;

      (d) the proximity of manned aircraft operations;

      (e) the proximity of aerodromes, airports and heliports;

      (f) the location and height of obstacles, including wires, masts, buildings, cell phone towers and wind turbines;

      (g) the predominant weather and environmental conditions for the area of operation; and

      (h) the horizontal distances from persons not involved in the operation.  (Penalty assessed: $456.00)

    • CAR 901.47(2) Subject to section 901.73, no pilot shall operate a remotely piloted aircraft at a distance of less than

        (a) three nautical miles from the centre of an airport; and

        (b) one nautical mile from the centre of a heliport.  (Penalty assessed: $456.00)

      • CAR 901.54(1) Subject to subsection (2), no person shall operate a remotely piloted aircraft system under this Division unless the person

          (a) is at least 14 years of age; and

          (b) holds either

          (i) a pilot certificate — small remotely piloted aircraft (VLOS) — basic operations issued under section 901.55; or

          (ii) a pilot certificate — small remotely piloted aircraft (VLOS) — advanced operations issued under section 901.64.  (Penalty assessed: $456.00)

        Add that all up? It comes to $3021.00. Those are pretty significant consequences for the pilot.

        Below: The blue and red lines indicate the drone’s path; you can see at the top right the maximum altitude was more nearly 900′ AGL, and the drone was at that height for roughly a third of its time in the air.

        A CAUTIONARY TALE

         

        YOW was pleased to see that Transport Canada took this incident seriously. And Michael Beaudette hopes this incident can be used to raise awareness.

        “Firstly, to remind drone operators that Transport Canada has regulations regarding drones operating near airports and aerodromes to ensure the safety of the public both in the air and on the ground,” he says. “Secondly, that individuals who are not aware of, or do not respect these regulations can be detected and held accountable, as in this case, subjected to fines that could be in the thousands of dollars.”

        Of course, these flights would likely have gone undetected were it not for YOW’s Drone Detection Pilot Project. This ongoing project, you may be aware, recorded multiple illegal flights during the so-called “Freedom Convoy” protests in Ottawa, and was put to use during US President Joe Biden’s 2023 state visit.

        “It has opened our eyes as to how many drones are active in the National Capital Region, particularly, in and around our approach paths of our runways and in the immediate vicinity of the airport itself,” says Beaudette.

        “It has also led to collaborative efforts between Transport Canada, NAV Canada and multiple Class 1 airports to become better aware of this issue and to develop contingencies to respond to incidents such as the one we experienced in Dec 2022.”

        INDRO’S TAKE

         

        InDro Robotics, like other Canadian professional operators, has a healthy respect for the CARS regulations. They are there for a reason, and not following the regs can lead to serious consequences. In fact, we wrote at length about a collision between an York Regional Police drone and a Cessna at the Buttonville Airport.

        “There can be no question that drones flying near active runways poses a significant – and completely avoidable – threat,” says InDro Robotics CEO Philip Reece, who is also a licensed private pilot.

        “The regulations are there for a reason: To protect the safety of crewed aircraft, as well as people and property on the ground. InDro is proud to be the core technology partner of the YOW Drone Detection Pilot Project – and this incident is a perfect reason why.”
