Thirty-one drones detected at Niagara Falls during eclipse – most of them breaking regulations

Thirty-one drones detected at Niagara Falls during eclipse – most of them breaking regulations

The solar eclipse attracted more than sightseers to Niagara Falls.

It also brought out drones – with as many as 31 detected at a single point in time. A few of those drones were authorised to be flown by law enforcement, but the majority were being flown by people who either weren’t aware of the regulations, or wilfully ignored them.

That’s because Niagara Falls is Class F Airspace. And the Park makes the policies very clear:

“Niagara Parks does not permit the use of drones within the property for any recreational purposes. Use of drones for commercial projects (commercial film, photography, survey or engineering work, etc.) may be considered and approved under a Permit,” reads the Park’s website page outlining the rules for film, photography, recording and drones. It goes on to the nuts and bolts of the airspace restriction.

“The airspace surrounding Niagara Falls is classified as CYR-518 Class F Restricted Airspace which further requires a Letter of Authorization from Transport Canada prior to Niagara Parks issuing a permit. Transport Canada’s authorization is required no matter the size or weight of the drone or how low or high the flight path.”

So no, you can’t take your sub-250g drone and think you’re in the clear.

But that didn’t stop a lot of people from putting drones into the air. And that’s cause for concern, given that helicopters and other traditional aircraft with special permission are in that same airspace for tours.

THE NEWS

 

Word of the multiple drones in the air came at the Canadian Hazmat and CBRNE Summit in Kitchener, where that acronym stands for Chemical, Biological, Radiological, Nuclear, and Explosive. It brought together First Responders, law enforcement and Hazmat specialists from across the country. The conference featured a heavy emphasis on how technology – drones, ground robots, ROVs, counter-UAS systems and more – have become essential tools for law enforcement and other First Responders.

During one of the sessions focussing on the D-Fend Solutions counter-UAS system, it was revealed that the system was in use in an exercise with Niagara Police during the solar eclipse to monitor drones. It’s a critical area because there are often crewed aircraft, helicopters in particular, taking tourists for flights over the falls. It is also, as noted, restricted airspace where no drones that do not have special authorisation should be in the air.

But the system picked up plenty of them.

“We saw at one point 31 drones in the air at one time at Niagara Falls during the eclipse,” David Beatty, Director of Sales for D-Fend Canada Solutions, said in a presentation. That kind of traffic, he added, means “a significant possibility of a mid-air collision not just between the drones, but also with the manned aviation that was flying at the same time at the same place.”

 

INTRUDERS

 

A small number of those drones were being flown by law enforcement and marked as “authorised” by the D-Fend Solutions system operator. But the vast majority were not. And not only were those drones in restricted airspace, at least one was detected breaking two other regulations: It was flying at an altitude of 1640′ above ground level and far Beyond Visual Line of Sight. (Transport Canada regulations limit drones – in airspace where they can be flown – to 400′ AGL and within Visual Line of Sight without special authorisation.)

“We identified the operator was four kilometres away flying at that altitude which was impeding both fixed wing and rotary aviation,” said Beatty in a follow-up interview with InDro Robotics. “Our understanding is that Niagara Police, because they have the residence location, will be conducting followup visits to the perpetrators.”

The D-Fend Solutions team was also able to relay information about drone positioning in real-time to a helicopter pilot who was carrying out flights over the falls, ensuring he had airspace awareness.

THE D-FEND SOLUTIONS SYSTEM

 

Developed in Israel, D-Fend Solutions originally began as a counter-drone solution for multiple Tier One agencies – meaning special forces and other elite services in the military and intelligence sectors around the world. Current clients listed on its website include three US federal departments: Defence, Homeland Security and Justice. A D-Fend system is also being evaluated for airport use by the FAA.

But D-Fend Solutions is now seeing opportunities in the broader market. This has come with both the widespread proliferation of drones, as well as their potential to be modified for nefarious and criminal purposes – including the frequent attempts to deliver contraband to prison yards.

“We were primarily dealing in the military realm, but based upon the threats that have occurred to public safety we’ve expanded into that marketplace,” explained Beatty. D-Fend Solutions products have been used at large public gatherings, to detect and mitigate drones at prisons and near critical infrastructure – including major airports.

And while drones can potentially cause conflict with traditional crewed aircraft, Beatty says there’s concern about another threat that has emerged in recent years.

“As we see in the conflict in the Ukraine, they are the poor man’s Air Force. Drones are very easily weaponised, and that could be someone flying the drone directly into someone, or placing some form of munition or chemical irritant on it.”

Beatty says clients have also seen an increase in the use of drones at protests, flying dangerously close over the heads of people – and even interfering with police drone activity.

HOW IT WORKS

 

 

There’s a variety of types of c-UAS systems on the market. They range from direct energy type weapons (think lasers) to kinetic (nets, etc.), frequency jamming and radar. The D-Fend Solutions system is a passive cyber-solution, meaning there’s no direct jamming or kinetic action. It also meets what are sometimes called the “Four Pillars” of a complete c-UAS system, including the ability to detect, track, identify and mitigate.

“We detect drones at ranges in excess of five kilometres,” says Beatty. “We will track the drone so we know its flight path. We identify the drone to the point where we get the serial number of the drone, the controller, the make and model of the drone, which then leaves us open to the mitigation.”

Before we get to mitigation options, it’s worth explaining that the D-Fend Solutions system is constantly listening for the unique RF signatures of the C2 link between the drone and the pilot on the ground. That’s how it detects not only the type of drone but also its telemetry.

In terms of mitigation, there are multiple options. D-Fend Solutions can set up a geofence, for example, that prevents drones marked as unauthorised from flying into a certain area. They’ll simply hit the boundaries of that geofence and be sent back to the operator. A rogue drone can also be forced to simply stop and hover in a location so that ground observers can get a closer look to determine if it poses a threat.

“The final option is that we can take control of the drone and send it on a safe passage to a safe collection point. And the emphasis is at no time is that drone ever without an owner.”

And how does the system do that passively, without jamming frequencies (where Industry Canada has some pretty strict rules)? Quite simply, it can trick the drone so that D-Fend Solutions becomes the control system.

SOMETIMES, IT’S ABOUT EDUCATION

 

The D-Fend Solutions system identified the location of the drone pilots violating the regulations at Niagara Falls on the day of the eclipse. An officer involved said during the conference there will be a follow-up with the pilot of that BVLOS drone flying at 1640′, since they have the address of the operator. It’s unclear whether this will be an informal education session, or whether any further action will be taken.

But sometimes, education is also a key tool. And that’s enabled by the system pinpointing the location of the pilot.

“This allows for a form of soft policing – in lieu of mitigating the drone, the police are able to educate the public with direct intervention by police units and the drone operator,” says Beatty.

Thankfully, there were no mishaps on April 8. Crewed air assets (and police drone operators) were kept in the loop on the location of all unauthorized drones.

INDRO’S TAKE

 

The D-Fend Solutions system provided important airspace awareness – and was a critical safety tool – during the eclipse event at Niagara Falls. The system has been demonstrated at several other major public events in Canada, providing critical awareness to law enforcement and other First Responders. The company’s EnforceAir product won first place for hardware and systems design at the 2023 AUVSI XCELLENCE awards.

“There’s a growing demand for c-UAS products globally, whether for public safety, critical infrastructure, airport security – even for protection from pirates on the high seas,” says InDro Robotics CEO Philip Reece.

“D-Fend Solutions provided an important service during the Niagara demonstration, and its ability to mitigate without jamming or kinetics is impressive.”

We’d be remiss if we didn’t also mention Bravo Zulu Secure, an InDro sister company that also offers detection and mitigation solutions. The incident detailed above is also reminiscent of the detection of many illegal drone flights in Ottawa during the convoy protests. If you haven’t seen that one, it’s definitely worth a read.

 

InDro Robotics flies in urban wind tunnels for National Research Council project

InDro Robotics flies in urban wind tunnels for National Research Council project

By Scott Simmie

 

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.

Below: The view from the InDro dashboard, showing a wishbone-shaped appendage carrying two anemometers

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.

FLYY’s Kate Klassen on the importance of drone training

FLYY’s Kate Klassen on the importance of drone training

May 26, 2023 | Drones, Education, Industry News

By Scott Simmie

 

Here’s a quick quiz for you: How many drones are registered with Transport Canada?

Take your best guess.

The answer? According to the latest Transport Canada RPAS Team Newsletter, the number is 86,131. That’s a lot of drones. Many of these – we’re confident the majority – are recreational/hobbyist machines. But the growing service provider sector is also a big contributor.

Quiz Number Two: How many Special Flight Operations Certificates were issued by Transport Canada in 2022? The answer here is 814, with the following breakdown:

  • Beyond Visual Line of Sight Operations: 62
  • Flying higher than 400 feet AGL: 48
  • Flying in or near Department of National Defence airspace: 56
  • Special Aviation or Advertised Events: 172
  • RPAS weighing over 25 kilograms: 41

The math-inclined might notice those numbers don’t add up to 814. The final category – with 435 SFOCs issued in 2022 – is for Foreign Operators.

“It’s pretty obvious, but there’s been an incredible growth in the use of drones across all sectors,” says Kate Klassen, a licensed traditional aircraft pilot and flight instructor. She’s also InDro’s Strategy and Implementation Specialist.

“And based on what I’ve seen – including my work with the Canada Drone Advisory Committee (CanaDAC), these numbers will continue to grow for many years to come.”

Below: A professional drone operation

 

LICENSED PILOTS

 

Along with the growth in registered drones, there’s been a commensurate growth in the number of licensed RPAS pilots in Canada. Transport Canada has issued 86,709 Basic Pilot Certificates, and 10,060 Advanced Pilot Certificates. Advanced RPAS Certificates allow a pilot to fly in controlled airspace, closer than 30 metres to bystanders, and nearer than 3 NM (5.6 km) to airports and 1 NM (1.9 km) to heliports.

And of that number? Roughly one in eight received their training from InDro’s Kate Klassen.

Klassen was a pioneer in the training world, developing an online course that was both educational and entertaining. She did that prior to joining InDro, and some 10,000 people took her online course. That’s a phenomenal number.

And she’s at it again, with a series of online courses at FLYY.

We’ll get into FLYY – and the importance of training – in a moment. But first, let us more fully introduce you to Klassen.

She’s a commercial pilot and a flight instructor for both airplanes and RPAS. She’s been involved with aviation for the past 16 years and holds a Management of Technology MBA from Simon Fraser University. Klassen serves as a Director with the Aerial Evolution Society of Canada (formerly Unmanned Systems Canada/Systèmes Télécommandé Canada) and was a Director for BC/YK with COPA (Canadian Owners and Pilots Association). She was also Co-Chair of Canada’s Drone Advisory Committee (CanaDAC), working closely with Transport Canada. She’s an expert in regulations and training.

Plus, she’s an amazing educator.

Below: A screen grab of Klassen from one of the FLYY instructional videos

Kate Klassen Drone Training

WHY BOTHER WITH A COURSE?

 

That’s a good question. Especially when there are options like YouTube, where you can find plenty of videos of people in their basements offering what they say are the knowledge requirements to obtain your Basic or Advanced RPAS Certificate.

We put that question to Kate.

“YouTube can be a great resource, but the challenge is knowing the accuracy and validity of the information,” she says.

“You want to trust the training provider, know their credentials and that they have the experience and expertise to be the one providing the training. In addition to video modules, FLYY also provides downloadable resources, interactive lessons and the ability to download for offline viewing.”

 

MORE THAN THE BASICS

 

What differentiates FLYY from some of the other online offerings?

For starters, Kate has deep expertise as both a commercial and RPAS pilot, as well as being an instructor. So you can have confidence you’re getting the Transport Canada knowledge requirements that ensure you’ve getting the fundamentals you need.

But FLYY offers more than just the tools to earn your Basic or Advanced RPAS Certificate.  The website has a module (and templates) to help you create your own Standard Operating Procedures, including a comprehensive pre-flight checklist. Another popular offering is the Flight Review preparation package. That package, which includes typical questions an Advanced RPAS Certificate candidate would receive at their in-person Flight Review, is designed to help ensure you pass that final step your first time. (And, given that most in-person Flight Reviews cost $200-$300, you really do want to pass your first time around.

 FLYY also offers Flight Reviews, regardless of your location in the country. Plus, once you’re registered with the site and taking a course, you’ll have access to an internal social hub where you can ask questions, post photos, and interact with other students and graduates of the FLYY program.

“I’m always happy to answer questions from students – and we get some good ones,” says Klassen. “This is something else you won’t get if you rely on a free online course. The courses have been carefully designed to ensure student success, and that’s also something I’m personally very much invested in. In fact, I like being a phone-a-friend lifeline for operators. It keeps me on my toes and problem solving at the pace of the industry.”

 

SPECIALIZED SKILLS

 

Drones have come a long way in the past decade. Like, a *really* long way. Think about it: DJI released its first Phantom in 2013 – a machine that required a separate GoPro in order to capture images. Now you can purchase a sub-250 gram drone with amazing range, connectivity and video/still qualities for less than $1,000.

But – particularly for those planning to become service providers or seeking professional employment – the knowledge base required has become more demanding. Gone are the days when having 50 hours of recreational drone flights might open the door to a job. Increasingly, employers are looking for people with highly specialised skills. They want candidates with experience flying thermal missions, capable of creating a LiDAR 3D digital twin – and much more.

Below: An Aerometrix methane-sniffing drone. Increasingly complex drones and drone operations require highly skilled pilots

 

Aerometrix

MICRO-CREDENTIALS

 

The future of training, at least from Klassen’s perspective, will involve obtaining credentials for operations requiring specific skillsets. These would be short, focussed courses – online or in-person – that would provide pilots with the skills they’ll need to carry out more complex flights (and with more complex sensors). Upon successful completion, a pilot would receive a certification that will become recognized as the standard for that industry.

Geospatial Information Systems (GIS), photogrammetry, mapping, volumetric calculations, BVLOS flights are just a few examples where Klassen envisions Micro-Credential courses would be the most effective route to obtaining skills.

“These are definitely skills that are pre-requisites for many drone jobs and require specialized training,” says Klassen. “Upon successful completion, a pilot would receive a certification or badge that’s recognized by the industry.”

Klassen is currently planning Micro-Credential courses for FLYY.

“Micro-Credentials will one day be just as important in this field as obtaining your Advanced RPAS Certificate,” says Klassen. “And with the new facility that’s coming in Ottawa at Area X.O, we’ll have a location where training, testing and evaluation for highly complex operations can take place in a controlled environment.”

(FYI, we took a deeper dive into the case for Micro-Credentials here.)

 

ADVANCED TESTING

 

That new site, which we’ve written about here, is designed for both drones and ground robots. Drone pilots will face a demanding NIST (National Institute of Standards and Technology) course, built to the exacting specifications created by ASTM (the American Society for Testing and Materials). It will also feature a large enclosed, netted area where specialised drone training and testing can be carried out. Complex testing or failsafe evaluation – missions that might normally require a Special Flight Operations Certificate – can be safely carried out within that netted enclosure without the need for special permissions.

The facility, which will open in June, has been funded by Invest Ottawa as a strategic investment in Area X.O. The facility will be operated by InDro Robotics. It is the first of its kind in Canada.

“For the first time we’re seeing a ground and air robot (drone) training and testing space and I think we’ll see those technologies work more closely together in the future, too,” says Klassen. “As an educator, I’m excited for the course offerings we’ll be able to put together. So much thought has gone into the details and facilities in this space and I can’t wait to see how it’s received.”

Below: A look at the new facility during construction in late May.

 

INDRO’S TAKE

 

InDro Robotics was one of the first companies in Canada to offer specialized drone training – working with law enforcement and First Responders onsite and at Salt Spring Island. InDro takes training very seriously, which is why we partnered with Kate Klassen to create FLYY.

“We share Kate’s belief that demand for complex drone training and testing will only increase. We also agree that Micro-Credential courses and badges will be an important offering for those wishing to take their skills to the next level,” says InDro Robotics CEO Philip Reece.

“Between Kate’s excellent FLYY program and the forthcoming Area X.O facility, we’ll be creating and delivering cutting-edge training customized to meet growing industry demands.”

What InDro does

What InDro does

Sep 7, 2022 | InDro Commander, InDro News, InDro Pilot, InDro Sentinel, Innovation

By Scott Simmie

 

Have you ever wondered: What exactly InDro Robotics does?

The answer might surprise you.

InDro is often described as a research and development company. While accurate, that isn’t very explanatory. So we’ll give the first word to CEO Philip Reece.

“InDro Robotics does a lot of different things – ranging from product development to service provision to creating and building solutions for global clients,” he says. “But all of these tasks have some things in common:

“This is an engineering-first company – dedicating to inventing, enhancing and deploying technologies and products that make difficult work easier and more efficient. Customers purchase these technologies, and we are also a service provider using these InDro innovations.”

That’s a good starting point. But what does that actually look like? We thought a good way to explain this might be to look at some of the milestones the company has accomplished between September of 2021 and 2022.

There are, unfortunately, some that we’re prohibited from telling you about due to non-disclosure agreements with clients. But even without those, it’s been a very productive year.

InDro Commander

We’ll start with something that has allowed many clients to quickly customise and deploy ground robots. You’ll see this in the image below; it’s the module sitting directly on top of the robot chassis below. Specifically, it’s toward the front of the chassis above the InDro Robotics logo.

InDro Commander

The process

 

There’s an interesting backstory here. One of the things InDro is known for is building custom robots designed for specific tasks. But building robots – especially building multiple robots with different functionalities – is hard work.

We have a head start on this process, because we use the excellent platforms built by AgileX, China’s leading producer of quality robotic platforms and locomotion systems. But – and you can ask any robot builder – the real challenge is building robots that do things besides move.

You need to integrate sensors – everything from optical and thermal sensors to LiDAR and even arms with end effectors. You’ve got to figure out how to power these sensors and pull their data – a task that involves much more than wiring. With most robots, it means finding and integrating the proper software from the Robot Operating System libraries (ROS and ROS2). Then you generally need an onboard computer to process that data – along with coming up with a solution to moving that data from the robot to somewhere else.

Our engineering team thought there had to be a better way. In particular, lead engineer Arron Griffiths envisioned a module that might act like a kit to make this process much, much easier. InDro Robotics then developed and tested a module that could be added to most ground robotic platforms. It contains a powerful Jetson computer for onboard EDGE processing, multiple USB slots for adding peripheral sensors, two wide-angle cameras to give the operator a 360° view of the robot’s surroundings, and more.

That “more” includes the ability to operate the robot, in realtime, over a 5G or 4G cellular connection. The browser-based console provides data from all sensors in a clean and easy to navigate dashboard. And the operation? You can simply use an Xbox controller and operate your newly integrated robot from down the street – or across the country.

You can learn more about InDro Commander in this story. But the point here is that our engineers identified a problem and came up with a solution. Many of our products have a similar origin: Thinking of a new way to do things that’s easier and more efficient.

InDro now regularly manufactures and ships Commanders to clients globally, providing the ability to rapidly customise any ground robot utilising the Robot Operating System – without all the hassle. (If you’re interested in more details, feel free to reach out to Account Executive Luke Corbeth.)

Now that you’ve got the Commander basics, let’s take a brief look at our ground inspection robot Sentinel.

 

InDro Robotics Sentinel

Location, location, location

 

The phrase doesn’t just apply to real estate.

Many companies have valuable assets in remote locations. To inspect such locations generally means dispatching one or two employees to make the often-long trek and then simply walk around and ensure things are working as they should be. They’ll check for any signs of corrosion or wear, perhaps watch and listen for electrical arcing or test for thermal anomalies, even watch out for signs that wildlife has been chewing on wires or building nests in locations that might pose a risk. Inspectors are also frequently dispatched following violent weather events.

InDro started thinking about this problem, with a particular focus on electrical substations – often-remote and uncrewed facilities where the current from high-voltage transmission Iines is stepped-down for delivery to consumers. What if a robot could be placed on site that could carry out these inspections remotely? In fact, what if InDro took the InDro Commander module and customised a new ground robot for the task?

That’s how Sentinel came to be. The tracked robot features a 30x optical tilt-pan-zoom camera, a thermal sensor – along with any additional sensors clients would like incorporated. Sentinel can autonomously return to its wireless charging base and can literally be left on its own for months. An operator can remotely carry out regular inspections, read gauges, capture high-resolution photo and video, check for thermal anomalies – and generally accomplish nearly everything that could be carried out by a human inspector without the time and expense. Plus, Sentinel can be dispatched within minutes when necessary.

You can read more about Sentinel here. The robot also recently took part in exhaustive testing at the Electrical Power Research Institute’s (EPRI) substation test facility in Lenox, Massechusetts.

This is a great example of where one InDro innovation – the Commander module – helped pave the way for a second innovation: Sentinel.

It also contributed to a third: The ROLL-E delivery robot:

 

Delivery Robot

ROLL-E

 

ROLL-E is another beneficiary of the InDro Commander invention. This delivery robot is capable of remotely teleoperated urban deliveries, such as from a retail outlet to a home.

InDro has already completed trials with London Drugs at a Victoria location, delivering goods purchased online for curbside pickup.

InDro now has a second-generation ROLL-E, which the company will be unveiling shortly. ROLL-E 2.0 has been purpose-built to maximize integration into an urban environment with features like signals, brake and running lights – and a series of cameras (including depth perception cameras) to provide the operator with a 360° view of ROLL-E’s surroundings. Goods are contained in a secure cargo bay that opens only when the recipient interacts with a touch-screen.

And that’s not all.

InDro is currently building the InDro Backpack – a smaller version of Commander. Its purpose? To offer the same capabilities for teleoperation and high speed data transmission on the Unitree GO1 and its other quadrupeds.

Here’s a brief video demonstrating teleoperation of the GO1 as the backpack was under development; InDro anticipates the bolt-on 4G/5G system will be ready for clients later this fall.

 

What about drones?

 

Good question. While we were developing Commander, a similar but separate project was underway for aerial robots.

See that guy on the right? That’s Ahmad Tamimi, an engineer at InDro’s Area X.O location in Ottawa.

When this photo was taken in the fall of 2021, he was deep into something called NERDS (Network Enhanced Realtime Drone project). It was a technology challenge in conjunction with the Ontario Centre of Innovation, Ericsson and the ENCQOR 5G network – a testbed corridor that runs through Quebec and Ontario.

You can find full details of that project here – and a link to InDro’s White Paper on NERDS here. But in a nutshell, Tamimi created a module similar to Commander, only for Enterprise drones using the Pixhawk flight controller. It enables operations over cellular, including real-time dense-data uploads directly to the cloud during flight. It also broadcasts to nearby traditional aircraft that a drone is operating – a tremendous boost to BVLOS flights.

Here’s a picture of that module on top of our Wayfinder drone:

InDro Pilot

 

InDro didn’t stop there. The company created an entire software suite – InDro Pilot – for Enterprise drones (and, specifically, drones using the InDro Capsule).

That software makes it a snap to add and integrate other sensors onto drones and carry out low-latency flights over cellular networks. As with Commander, sensors can simply be plugged in to InDro Capsule, and the dashboard allows for drag-and-drop sensors modules to be added to the software suite. Want a winch? Simply add on the winch module and all operational controls and parameters are added to the InDro Pilot software. A robust and encrypted link between the InDro Ground Station and the drone ensures that any data collected remains secure. 

This project was completed in that 2021-2022 window we established earlier. InDro is currently creating a smaller and lighter InDro Capsule for commercialization of the entire InDro Pilot system. 

Here’s a screen grab of the winch software module:

One more time

 

And here’s a look at the complete system…

Again, if you’d like a more thorough look at that system you’ll find far more details here.

That’s not all…

 

As mentioned, it’s been a highly productive year at InDro. We’ve flown drones in the NRC Wind Tunnel in Ottawa for research on urban wind tunnels. The company has partnered with UBC, Honeywell and others on a major research project involving flights over 5G and using AI software to precisely predict energy demands and costs of any planned drone mission.

As drones begin deliveries at scale in the future, the data being obtained about the capabilities of 5G networks to handle multiple drones simultaneously – as well as costs – will be tremendously useful to the industry-at-large.

All this, while carrying out service provision for clients on a global scale, including this mission in Saudi Arabia. (That’s our photogrammetry/GIS specialist Eric Saczuk in the photo).

Before we forget…

 

InDro was also in the news this year for its role in the Drone Detection Pilot Project at the Ottawa International Airport.

During the protests in the nation’s capital, data obtained by the system revealed that scores of unauthorized drone flights were taking place in restricted airspace – including above Parliament Hill, over 24 Sussex Drive, and even near embassies and other sensitive locations.

InDro takes part in this project – and supplies the drone detection equipment for free – because there’s valuable data being obtained that contributes to both safety at YOW and informed policy and procedures.

In fact, the news even made the cover of WINGS magazine:

Drone detection

Wait, there’s more!

 

Hard to believe, but there is (and congrats for sticking through this long-ish read!).

InDro reached several other milestones between the fall of 2021 and 2022. The company can’t, unfortunately, share details of these due to non-disclosure agreements. But innovative solutions have been created for global clients. In one example, a prototype robot was so successful that InDro received orders for many more.

On top of that, the company has worked closely with industry and regulatory partners during this period, including delivering InDro Pilot-enabled drones to Transport Canada and assisting RPAS parachute manufacturer AVSS with testing of its latest product.

InDro’s Take

 

With an agile and motivated team, InDro Robotics has created multiple new and innovative products in the course of a single year. Some of these were created specifically for clients, while others were organic in nature. The development of InDro Commander has paved the way for multiple robots (Sentinel, ROLL-E, ROLL-E 2.0). In addition, the company has shipped custom Commander-enabled robots to clients – including one fully customized for Solar Farm inspection. Many clients are now order Commander modules to make the customization of their own ground robotics platforms a vastly easier process.

In addition, the development of the InDro Capsule and InDro Pilot system for Enterprise drones will soon allow clients to easily customize their RPAS with additional sensors, along with secure high-data bandwidth (direct to Cloud) and remote teleoperations via console over cellular networks. Stay tuned for more on that.

CEO Philip Reece got the first word in this summary; he also gets the last:

“I’m justifiably proud of our team for the multiple milestones we’ve surpassed during the past year,” he says. “InDro has created numerous products – and participated in multiple projects – where we’ve been able to push the envelope. Every single one of these products and processes uses technological innovations to make hard jobs easier, or to significantly expand the capabilities of drones and robots. The team has really hit its stride.”

Hopefully, this gives you a much better idea of What InDro Robotics Does. And why we proudly call ourselves an R&D company.

 

Methane detection via drone with Aerometrix

Methane detection via drone with Aerometrix

There’s no denying climate change. Whether it’s the recent and devastating floods in Pakistan, fires in Portugal – or the multiple rivers globally that have dropped to historically low levels – the planet’s equilibrium has been changing.

While carbon dioxide emissions get much of the press, methane is one of the most potent contributors to the problem of greenhouse gases.

“Methane has more than 80 times the warming power of carbon dioxide over the first 20 years after it reaches the atmosphere,” states the Environmental Defense Fund.

“Even though CO2 has a longer-lasting effect, methane sets the pace for warming in the near term.”

That’s a key reason why the detection of methane emissions has become a priority. It’s also a large part of why Aerometrix – a company specialising in methane detection using drones – was formed.

Below: One of the early Aerometrix rigs for methane detection. The sensor is at the forward end of the counter-weighted rod to keep it clear of prop wash.

Aerometrix

 

Before we get more into what Aerometrix does (and how it does it), we should point out there’s an InDro Robotics connection here. InDro CEO Philip Reece, along with Michael Whiticar, founded the company. Aerial operations for Aerometrix are carried out by InDro Robotics.

“We felt there was a void in the marketplace for the detection of methane and other gases,” explains Reece. “We also wanted to approach this from an engineering-first perspective, ensuring that we were using, and even developing, the best available sensors and workflow.”

Aerometrix uses two different types of sensors for methane detection. The first is the proprietary GasMap sensor, which is capable of detecting methane in parts per billion (ppb). This laser-based sensor had its origins at NASA’s Jet Propulsion Laboratory, where it was developed for Mars missions. Aerometrix has further refined that sensor and has used it to accurately map methane emissions at petrochemical plants, gas wells, landfills – and even on agricultural sites. (Animals, particularly cows, are a significant methane source.)

“GasMap uses laser spectroscopy,” explains Peter Sherk, an electronics engineer with Aerometrix. “It uses the absorption of lasers by methane to detect concentration. And it’s very precise – detecting not only its presence, but how much there is at a given point in time and space right down to parts per billion.”

The sensor maps methane (and other gases) by flying horizontally through the plume. When multiple passes at different altitudes have been completed, a “curtain” is obtained. (Don’t worry, we won’t ask you to carry out the calculation – besides, our FluxCurtain software does that.)

Flux Curtain

Zig-zag

 

As mentioned, the drone flies horizontally through the plume – with each parallel flight at a slightly higher altitude. The sensor is constantly capturing georeferenced data which Aerometrix then runs through software.

In the images below, you’ll see that zig-zag flight pattern. The blue lines at the bottom indicate methane concentrations. Not surprisingly, those concentrations begin to dissipate at higher altitudes as the methane plume mixes with the surrounding air.

The second image is what’s referred to as the actual “Flux Plane” – where the methane concentrations are represented visually by colour.

Efficiency

 

Though pipelines and facilities that handle methane are obvious places where detection is required, local city dumps are also interested in detecting – and even capturing – methane produced by buried garbage. But many are unaware of the efficiency and accuracy of using sensors like the GasMap mounted on a drone.

“A lot of landfills are doing methane detection already,” says Sherk, “but they’re using far less convenient methods. A lot of the time there’s someone walking back and forth with handheld sensors. With larger landfills any sort of grid pattern will take days and days – and walking over an old landfill can’t be a really healthy operation.Operating a drone is vastly more efficient. And the GasMap sensor is capable of detecting not only the presence of methane, but its concentration at various altitudes as the gas forms a plume and mixes with surrounding air.

Some landfills have been able to not only capture but exploit methane that was previously escaping. The Capital Regional District on southern Vancouver Island has been running a power generating plant on-site at the Hartland Landfill, fuelled solely by captured methane produced by decomposing garbage. It’s been doing so since 2004, creating enough energy to power 1,600 homes.

Recently, the volume of methane produced by the landfill has increased, and the power plant is nearing the end of its operational life. In 2023, the landfill will switch gears and process the biogas into natural gas – selling the product to FORTIS BC.

Kudos to the Capital Region District for having such foresight; the example also highlights how captured methane can be put to positive use.

Aerometrix has carried out surveys now at numerous landfills hoping to capture or otherwise mitigate methane emissions. Using FluxCurtain software, its reports turn what was previously an invisible problem into clear, actionable data that provide a clear picture of emissions and concentrations.

Methane Detection

Another sensor

 

We mentioned a second sensor also being used by Aerometrix. It’s called the LaserScan, and it’s a very lightweight sensor that also uses laser spectroscopy to detect the presence of methane.

Unlike the GasMap, the newer sensor is able to measure vertically. In other words, the drone can be flying directly above a plume and take a measurement straight down to the ground. While it’s not quite as precise as the GasMap sensor (parts per million, rather than parts per billion), the LaserScan does have an advantage when it comes to speed.

Because it does not rely on flying through the plume, the LaserScan is ideal for detecting emissions over large areas. By simply flying a grid pattern at a single altitude, it can rapidly identify emissions. At an altitude of 98.4′, it’s capable of detecting 500 ppm of methane with a plume diameter of one meter.

“While the Falcon is less precise than the GasMap sensor, it has a definite advantage when it comes to speed,” explains Keegan Richter, a mechanical engineer with Aerometrix.

In cases where greater precision is required, Aerometrix can fly two missions: The first with the LaserScan to rapidly detect the location of emissions – particularly over large landfills – followed by GasMap for parts-per-billion accuracy.

Methane Detection

InDro’s Take

 

We obviously have a special interest in Aerometrix, since InDro’s pilots and drones carry out its aerial missions.

Not surprisingly, since CEO Philip Reece is a co-founder, the mission of Aerometrix closely aligns with InDro’s guiding philosophy: Developing and utilising technology to increase efficiency and – whenever possible – contribute to positive change.

Arguably, the dramatic and apparently escalating shifts we’ve seen to global climate patterns are one of the most pressing problems on the planet. Methane is a key contributor to those changes.

The ability of Aerometrix to accurately detect methane emissions has already helped clients cap leaks and examine other methods for capturing this gas before it hits the atmosphere. Its missions have also meant that human beings are no longer exposed to hazardous environments while capturing data using handheld devices.

In our mind, those are both positive outcomes.
