Indro Robotics provides live drone video feed at Montreal Marathon in pilot medical project

Indro Robotics provides live drone video feed at Montreal Marathon in pilot medical project

By Scott Simmie

 

The Montreal Marathon, 2022 edition, was held over the weekend. The main event, the signature 42-kilometre run, took place early Sunday. And three InDro Robotics engineers were there.

They weren’t running, but were instead providing a live feed from drones. Those live feeds were being monitored on large video monitors by dedicated research assistants. They were assessing the quality of the feeds and their usefulness in detecting runners who might be in need of medical assistance.

Research project

 

InDro became involved with this through Dr. Valérie Homier, an Emergency Physician at McGill University Health Centre. She has long had an interest in how drones can be used in the health care sector, and has collaborated with InDro on two previous research projects.

One of those projects evaluated whether drones or ground delivery could transport simulated blood products more efficiently to a trauma facility – the Montreal General Hospital. Drones were faster.

The second project studied whether drones could help identify swimmers in distress at an IRONMAN event in Mont-Tremblant. You can find that research here.

With the Montreal Marathon coming up, Dr. Homier knew there would likely be medical events. There generally are.

“In these long-distance sporting events there are usually some significant injuries, including cardiac events and heat strokes,” she says.

These tend to be more likely in the later phases of events like marathons, after the athlete has already been under stress for an extended time. The thinking was that perhaps drones could be a useful tool.

Dr. Homier was particularly interested in whether two drones in the air, covering two critical segments toward the end of the marathon, could provide useful data. Specifically, would the live video feed be consistent enough in quality and resolution to be a useful tool?

This pilot aimed to find out.

InDro’s role

 

There was a lot of planning required for the mission to ensure the drones could provide continuous coverage and be safe for flying in an area with so many people. Project Manager Irina Saczuk (who happens to also be an RN) worked closely with Dr. Homier to help figure out the nuts and bolts of the InDro side of things.

InDro assigned three employees from the Area X.O facility to the project: Software developers Ella Hayashi and Kaiwen Xu, along with mechatronics specialist Liam Dwyer. All three hold Advanced RPAS certificates and took part in planning meetings to understand the mission and their roles. They also looked into optimising the drones’ video feeds to ensure the best quality would reach those monitoring remotely on large screens.

“At big-scale events such as this marathon, lots of people could go down with injuries,” says InDro’s Ella Hayashi. “But it can be hard to get timely support because roads are blocked. So drones have the potential to really help with sharing the precise location and other information when a person may need help.”

Worth noting here: The InDro engineers/pilots were not to be actively ‘looking’ for people in medical distress. Their role was simply to pilot the drones at the assigned locations and maintain a video feed that offered those watching the large-screen monitors with good situational awareness. In the event of an emergency, the pilots were to follow instructions, including moving in closer to a runner in distress.

 

Sub-250 grams

 

The team took four DJI Mini 2 drones to Montreal. Though InDro has a fleet of much larger and sophisticated drones the company has built, these consumer drones were perfect for the job. That’s because the Mini 2 is a sub-250 gram drone that can be flown near and over people. In the exceedingly rare event of a failure, the small device is unlikely to cause any substantial injury to someone on the ground. They’re also capable of very good video quality.

The team also used a third-party app – Airdata – to carry the video streams. The app created secure links for each drone’s feed that could be shared with those who would be monitoring the feed. Three drones were to be used in rotation so that two drones were always in the air providing live video at any given time. A fourth drone was onsite for backup.

“We modified the parameters and were streaming in 720p,” explains Dwyer. “We selected a lower resolution because on the bigger screen it didn’t have to be crystal clear but it needed to be smooth.”

There was, initially, some concern over whether the local LTE network would be able to handle the feed due to the large number of people using cellphones to capture and stream from the finish line.

“The night before the mission, a medical person told us there were going to be 20,000 people around the stadium,” says Xu. “We were worried about network connectivity, it was possible that our video streaming would not work. But actually the network was pretty good that day.”

Live Drone Video Feed

A useful exercise

 

Remember: This was simply a pilot project to determine if drones could provide a clean video stream that might be useful. The pilots were to focus on hovering the drones in two specific adjacent locations, with some overlap in their video to ensure they were not missing a spot of this critical part of the marathon.

“Our job was 100 per cent flying the drones,” says Dwyer. “Just straightforward, wide-angle shots with all runners in the field of view.”

We should mention here that InDro also took part in a simulated cardiac event prior to the marathon reaching this area. A medical dummy was placed in a location and one of the drone pilots was instructed to get closer for a better look. A small electric vehicle – think a large golf cart adapted for First Responder use – was dispatched. Chest compressions were performed on the dummy, which was then loaded into the vehicle. A drone followed as the vehicle drove to a nearby stadium and the victim was transported inside to the treatment area. The feed gave others on the Medi-Drone team an opportunity to see, in real-time, the progress of the patient’s arrival.

“The drone response really gave them an active timeline of when they should expect to receive this patient,” says Dwyer.

So the drones proved useful during a simulation. But how would they perform with runners during the actual marathon?

Below: The downhill segment monitored by InDro Robotics

From simulation to real-world

 

As the lead runners came in, the field wasn’t crowded. But, of course, it would become more congested.

When athletes are moving together en masse like this, Dr. Homier says there’s a certain flow that can be observed from the drone. Because that flow is consistent and smooth, a runner in distress literally pops up as looking out of place.

And it happened. Those watching the live feed spotted someone who appeared to be in distress. They had stopped, were hanging on to a railing on the side of the course. Then they fell over the railing, dropping to the grass. A drone pilot was asked to move in for a closer look. It was clear this runner needed help.

In fact, while the pilots were intended to simply hover their drones, Dr. Homier had anticipated such a scenario, and built it into the protocol for the pilot project. Suddenly, an InDro pilot had become part of a First Responder team, providing much-needed situational awareness.

“It was embedded in the research protocol, that eyes on the event becomes what is required,” she explains. “It was called into dispatch and pilots were able to provide eyes on the incident. That was amazing; dispatch came down after and brought us a radio.”

 

Lessons learned

 

For Dr. Homier, there’s still work ahead and a lot of data to be analyzed.

“There’s a lot to learn from this project, and there’s a way forward for multiple surveillance methods,” she says.  “And the drones are way up there. The view from above when monitoring moving crowds is just incomparable.”

Plus, says Dr. Homier, the project sparked a tremendous amount of interest from other healthcare professionals on site.

“The interest was incredible, coming from the drone pilots, the students, the medical directors, the medical staff – they all thought it was so cool,” she says.

“We’re talking about 250 people involved in the medical team. Many came to see the viewing station, so in terms of letting people know about this new use of the technology – that was also a great success.”

InDro’s take

 

We’re proud to be involved with this project – just as we’re proud to have collaborated previously with Dr. Valérie Homier on other research projects involving drones. In fact, we find this kind of research particularly meaningful.

“For us, using drones for good is much more than a catchy hashtag,” says InDro Robotics CEO Philip Reece. “Aerial and ground robots can perform so many useful tasks. We’ve helped securely deliver prescriptions to remote locations, COVID test supplies, and more. But playing a role in helping to ensure that someone in medical distress receives timely assistance is up near the top of the list. We look forward to the next project with Dr. Homier.”

And nice job, Ella, Kaiwen and Liam.

InDro’s ROLL-E 2.0 robot delivers to London Drugs customers in Surrey, BC

InDro’s ROLL-E 2.0 robot delivers to London Drugs customers in Surrey, BC

There’s a new robot in town.

That robot is InDro’s ROLL-E 2.0, and the town (well, city) is Surrey BC.

In the latest phase of an ongoing pilot project with London Drugs, the new version of InDro’s delivery robot was on the job September 9, delivering curbside orders to customers for touchless and convenient delivery. ROLL-E even delivered from the store to a customer’s home.

Let’s take a look at this robot, which features a number of innovations its predecessor, the original ROLL-E, did not have.

Delivery Robot

A leap from ROLL-E 1.0

 

You might recall that Indro Robotics carried out a longer-term pilot project at a location of London Drugs in Victoria, BC. The robot carried out regular curbside deliveries for customers who ordered online and wanted a touchless pickup experience.

The original ROLL-E worked great, but we learned some lessons that have resulted in an even more user-friendly robot. As a result, ROLL-E 2.0 features a host of new features, including:

  • A total of six cameras, including two sets of depth perception cameras at the front and rear for greater situational awareness for the operator
  • LED running lights, signal lights, brake lights
  • Large cargo bay (50kg capacity) that can be opened and closed remotely
  • Greater all-weather protection and a touchscreen interface for customers

Here’s a quick look at ROLL-E 2.0 on the job:

Tele-operated

 

ROLL-E 2.0 is a tele-operated robot, with an operator controlling it over the 4G or 5G cellular networks. That means the ‘driver’ could be in the local London Drugs outlet, or even hundreds of kilometres away. The person operating sees the view from all cameras, GPS location, ROLL-E health – and more – over a computer console. ROLL-E 2.0 is not yet a fully autonomous machine, but does have the capability to eventually be thinking on its own.

The first deployment – for curbside pickups in Victoria – was popular with customers and London Drugs staff. Pushing the envelope with home deliveries was the next logical step.

“Customers were pleased with both the convenience and experience of having goods delivered to their car by robot,” says InDro Robotics CEO Philip Reece. “This took things further, both literally and figuratively. Delivery robots will one day become commonplace, so London Drugs and the City of Surrey are really ahead of the game.”

London Drugs, meanwhile, is interested in continuing to assess the efficiency and customer acceptance of robot deliveries as part of the future of e-commerce.

“Following a successful pilot debut for ROLL-E earlier this year, we are thrilled to be further exploring its capabilities as we test home delivery in conjunction with Indro Robotics and the City of Surrey,” says Nick Curalli, London Drugs vice president of technology solutions. “This is an important step for our company as we look for innovative ways to serve our customers in the safest and most convenient way.”

By the way, that’s InDro’s Kate Klassen on the left in the photo below. She was ROLL-E’s operator for this project. 

 

Delivery Robot

The Surrey connection

 

Surrey was an ideal test bed. The city welcomes projects like this as part of its Urban Technology Test Lab, which accelerates innovative projects toward commercialisation.

“Responding to the need for technology testing areas, the Urban Technology Test Lab Pilot provides technology firms with access to safe, local test zones,” said Surrey Mayor Doug McCallum. “Without the opportunity to field test in a real-world setting, many of the products could not proceed to final development and commercialisation. I am thrilled to see ‘ROLL-E 2.0’ hit Surrey streets for testing, and I am excited to see this initiative launch. The future truly does live here in the City of Surrey.”

ROLL-E 2.0 Surrey

InDro’s take

 

As an R&D company, InDro has always taken a “Crawl, walk, run” approach when it comes to testing new technology. The initial deployment in Victoria with ROLL-E 1.0 was the crawl phase, putting the product through its paces in a real-world setting. ROLL-E 2.0’s development and testing in Surrey was the our first chance to walk; we’ll soon be ready to run.

For InDro Robotics, this is about more than a business case. The eventual widespread adoption of robots like these will end countless short trips by automobile to nearby stores for small orders.

“Because ROLL-E 2.0 is electric, these deliveries will eliminate carbon emissions that would have otherwise been created by people driving to the store and back,” says InDro CEO Philip Reece. “This project involves a single robot, but deploying these at scale in the future will have a measurable impact on C02.”

We’ll check in again when ROLL-E 2.0 starts running.

What InDro does

What InDro does

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.

Canada Drones

InDro Capsule

 

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:

Canada Drones

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:

Canada Drone

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.

Drones Canada

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).

Drones Canada

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. 

Drones Canada

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

By Scott Simmie

 

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

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.

Methane Detection
Methane Detection

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.
