Why Robots Are Flying Over Zanzibar and the Source of the Nile

An expedition in 1858 revealed that Lake Victoria was the source of the Nile. We found ourselves on the shores of Africa’s majestic lake this October, a month after a 5.9 magnitude earthquake struck Tanzania’s Kagera Region. Hundreds were injured and dozens killed. This was the biggest tragedy in decades for the peaceful lakeside town of Bukoba. The Ministry of Home Affairs invited WeRobotics to support the recovery and reconstruction efforts by carrying out aerial surveys of the affected areas. 


The mission of WeRobotics is to build local capacity for the safe and effective use of appropriate robotics solutions. We do this by co-creating local robotics labs that we call Flying Labs. We use these Labs to transfer the professional skills and relevant robotics solutions to outstanding local partners. Our explicit focus on capacity building explains why we took the opportunity whilst in Kagera to train two Tanzanian colleagues. Khadija and Yussuf joined us from the State University of Zanzibar (SUZA). They were both wonderful to work with and quick learners too. We look forward to working with them and other partners to co-create our Flying Labs in Tanzania. More on this in a future post.

Aerial Surveys of Kagera Region After The Earthquake

We surveyed multiple areas in the region based on the priorities of our local partners as well as reports provided by local villagers. We used the Cumulus One UAV from our technology partner DanOffice to carry out the flights. The Cumulus has a stated 2.5 hour flight time and 50 kilometer radio range. We’re using software from our partner Pix4D to process the 3,000+ very high resolution images captured during our 2 days around Bukoba.


Above, Khadija and Yussuf on the left with a local engineer and a local member of the community on the right, respectfully. The video below shows how the Cumulus takes off and lands. The landing is automatic and simply involves the UAV stalling and gently gliding to the ground. 

We engaged directly with local communities before our flights to explain our project and get their permissions to fly. Learn more about our Code of Conduct.


Aerial mapping with fixed-wing UAVs can identify large-scale damage over large areas and serve as a good base map for reconstruction. A lot of the damage, however, can be limited to large cracks in walls, which cannot be seen with nadir (vertical) imagery. We thus flew over some areas using a Parrot Bebop2 to capture oblique imagery and to get closer to the damage. We then took dozens of geo-tagged images from ground-level with our phones in order to ground-truth the aerial imagery.


We’re still processing the resulting imagery so the results below are simply the low resolution previews of one (out of three) surveys we carried out.


Both Khadija and Yussuf were very quick learners and a real delight to work with. Below are more pictures documenting our recent work in Kagera. You can follow all our trainings and projects live via our Twitter feed (@werobotics) and our Facebook page. Sincerest thanks to both Linx Global Intelligence and UR Group for making our work in Kagera possible. Linx provided the introduction to the Ministry of Home Affairs while the UR Group provided invaluable support on the logistics and permissions.

From the shores of Lake Victoria to the coastlines of Zanzibar

Together with the outstanding drone team from the State University of Zanzibar, we mapped Jozani Forest and part of the island’s eastern coastline. This allowed us to further field-test our long-range platform and to continue our local capacity building efforts following our surveys near the Ugandan border. Here’s a picture-based summary of our joint efforts.

We flew the Cumulus at a speed of 65km/h and at an altitude of 265m.


The Cumulus flew for 2 hours, making this our longest UAV flight in Zanzibar so far.


Khadija from Team SUZA explains to local villagers how and why she maps Zanzibar using flying robots.


Tide starts rushing back in. It’s important to take the moon into account when mapping coastlines, as the tide can change drastically during a single flight and thus affect the stitching process.

Using Swimming Robots to Warn Villages of Himalayan Tsunamis

Cross-posted from National Geographic 

Climate change is having a devastating impact on the Himalaya. On the Ngozumpa glacier, one of the largest and longest in the region, hundreds of supraglacial lakes dot the glacier surface. One lake in particular is known for its continuous volume purges on an annual basis. Near the start of the monsoon this summer, in less than 48 hours, it loses enough water to fill over 40 Olympic-sized swimming pools. To make matters worse, these glacial lakes act like cancers: they consume Himalayan glaciers from the inside out, making some of them melt twice as fast. As a result, villages down-valley from these glacial lakes are becoming increasingly prone to violent flash floods, which locals call Himalayan Tsunamis.

To provide early warnings of these flash floods requires that we collect a lot more geophysical and hydrologic information on these glacial lakes. So scientists like Ulyana (co-author) are racing to understand exactly how these glacial lakes form and grow, and how they’re connected to each other through seemingly secret subterranean channels. We need to know how deep and steep these lakes are, what the lake floors look like and of what materials they are composed (e.g., mud, rock, bare ice).

Ulyana, her colleagues and a small local team of Sherpa have recently started using autonomous swimming robots to automatically map lake floors and look for cracks that may trigger mountain tsunamis. Using robotics to do this is both faster and more accurate than having humans take the measurements. What’s more, robots are significantly safer. Indeed, even getting near these lakes (let alone in them!) is dangerous enough due to unpredictable collapses of ice called calving and large boulders rolling off of surrounding ice cliffs and into the lakes below. Just imagine being on a small inflatable boat floating on ice-cold water when one of those icefalls happen.

We (Ulyana and Patrick) are actively looking to utilize diving robots as well—specifically the one in the video footage below. This OpenROV Trident robot will enable us to get to the bottom of these glacial lakes to identify deepening ‘hotspots’ before they’re visible from the lake’s surface or from the air. Our plan next year is to pool our efforts, bringing diving, swimming and flying robots to Nepal so we can train our partners—Sherpas and local engineers—on how to use these robotic solutions to essentially take the ‘pulse’ of the changing Himalaya. This way they’ll be able to educate as well as warn nearby villages before the next mountain floods hit.

We plan to integrate these efforts with WeRobotics (co-founded by co-author Patrick) and in particular with the local robotics lab that WeRobotics is already setting up in Kathmandu. This lab has a number of flying robots and trained Nepali engineers. To learn more about how these flying robots are being used in Nepal, check out the pictures here.

We’ll soon be adding diving robots to the robotic lab’s portfolio in Nepal thanks to WeRobotics’s partnership with OpenROV. What’s more, all WeRobotics labs have an expressed goal of spinning off  local businesses that offer robotics as services. Thus, the robotics start-up that spins off from our lab in Nepal will offer a range of mapping services using both flying and diving robots. As such, we want to create local jobs that use robotics (jobs that local partners want!) so that our Nepali friends can make a career out of saving their beautiful mountains.

Humanitarian Robotics: The $15 Billion Question?

The International Community spends around $25 Billion per year to provide life saving assistance to people devastated by wars and natural disasters. According to the United Nations, this is $15 Billion short of what is urgently needed; that’s $15 Billion short every year. So how do we double the impact of humanitarian efforts and do so at half the cost?


Perhaps one way to deal with this stunning 40% gap in funding is to scale the positive impact of the aid industry. How? By radically increasing the efficiency (time-savings) and productivity (cost-savings) of humanitarian efforts. This is where Artificial Intelligence (AI) and Autonomous Robotics come in. The World Economic Forum refers to this powerful new combination as the 4th Industrial Revolution. Amazon, Facebook, Google and other Top 100 Fortune companies are powering this revolution with billions of dollars in R&D. So whether we like it or not, the robotics arms race will impact the humanitarian industry just like it is impacting other industries: through radical gains in efficiency & productivity.

Take Amazon, for example. The company uses some 30,000 Kiva robots in its warehouses across the globe (pictured below). These ground-based, terrestrial robotics solutions have already reduced Amazon’s operating expenses by no less than 20%. And each new warehouse that integrates these self-driving robots will save the company around $22 million in fulfillment expenses alone. According to Deutsche Bank, “Bringing the Kivas to the 100 or so distribution centers that still haven’t implemented the tech would save Amazon a further $2.5 billion.” As is well known, the company is also experimenting with aerial robotics (drones). A recent study by PwC (PDF) notes that “the labor costs and services that can be replaced by the use of these devices account for about $127 billion today, and that the main sectors that will be affected are infrastructure, agriculture, and transportation.” Meanwhile, Walmart and others are finally starting to enter the robotics arms race. The former is using ground-based robots to ship apparel and is actively exploring the use of aerial robotics to “photograph ware-house shelves as part of an effort to reduce the time it takes to catalogue inventory.”

Amazon Robotics

What makes this new industrial revolution different from those that preceded it is the fundamental shift from manually controlled technologies—a world we’re all very familiar with—to a world powered by increasingly intelligent and autonomous systems—an entirely different kind of world. One might describe this as a shift towards extreme automation. And whether extreme automation powers aerial robotics, terrestrial robotics or maritime robots (pictured below) is besides the point. The disruption here is the one-way shift towards increasingly intelligent and autonomous systems.


Why does this fundamental shift matter to those of us working in humanitarian aid? For at least two reasons: the collection of humanitarian information and the transportation of humanitarian cargo. Whether we like it or not, the rise of increasingly autonomous systems will impact both the way we collect data and transport cargo by making these processes faster, safer and more cost-effective. Naturally, this won’t happen overnight: disruption is a process.

Humanitarian organizations cannot stop the 4th Industrial Revolution. But they can apply their humanitarian principles and ideals to inform how autonomous robotics are used in humanitarian contexts. Take the importance of localizing aid, for example, a priority that gained unanimous support at the recent World Humanitarian Summit. If we apply this priority to humanitarian robotics, the question becomes: how can access to appropriate robotics solutions be localized so that local partners can double the positive impact of their own humanitarian efforts? In other words, how do we democratize the 4th Industrial Revolution? Doing so may be an important step towards closing the $15 billion gap. It could render the humanitarian industry more efficient and productive while localizing aid and creating local jobs in new industries.

This is What Happens When You Send Flying Robots to Nepal

In September 2015, we were invited by our partner Kathmandu University to provide them and other key stakeholders with professional hands-on training to help them scale the positive impact of their humanitarian efforts following the devastating earthquakes. More specifically, our partners were looking to get trained on how to use aerial robotics solutions (drones) safely and effectively to support their disaster risk reduction and early recovery efforts. So we co-created Kathmandu Flying Labs to ensure the long-term sustainability of our capacity building efforts. Kathmandu Flying Labs is kindly hosted by our lead partner, Kathmandu University (KU). This is already well known. What is hardly known, however, is what happened after we left the country.

Screen Shot 2015-11-02 at 5.17.58 PM

Our Flying Labs are local innovation labs used to transfer both relevant skills and appropriate robotics solutions sustainably to outstanding local partners who need these the most. The co-creation of these Flying Labs include both joint training and applied projects customized to meet the specific needs & priorities of our local partners. In Nepal, we provided both KU and Kathmandu Living Labs (KLL) with the professional hands-on training they requested. What’s more, thanks to our Technology Partner DJI, we were able to transfer 10 DJI Phantoms (aerial robotics solutions) to our Nepali partners (6 to KU and 4 to KLL). In addition, thanks to another Technology Partner, Pix4D, we provided both KU and KLL with free licenses of the Pix4D software and relevant training so they could easily process and analyze the imagery they captured using their DJI platforms. Finally, we carried out joint aerial surveys of Panga, one of the towns hardest-hit by the 2015 Earthquake. Joint projects are an integral element of our capacity building efforts. These projects serve to reinforce the training and enable our local partners to create immediate added value using aerial robotics. This important phase of Kathmandu Flying Labs is already well documented.


What is less known, however, is what KU did with the technology and software after we left Nepal. Indeed, the results of this next phase of the Flying Labs process (during which we provide remote support as needed) has not been shared widely, until now. KU’s first order of business was to actually finish the joint project we had started with them in Panga. It turns out that our original aerial surveys there were actually incomplete, as denoted by the red circle below.


But because we had taken the time to train our partners and transfer both our skills and the robotics technologies, the outstanding team at KU’s School of Engineering returned to Panga to get the job done without needing any further assistance from us at WeRobotics. They filled the gap:


The KU team didn’t stop there. They carried out a detailed aerial survey of a nearby hospital to create the 3D model below (at the hospital’s request). They also created detailed 3D models of the university and a nearby temple that had been partially damaged by the 2015 earthquakes. Furthermore, they carried out additional disaster damage assessments in Manekharka and Sindhupalchowk, again entirely on their own.

Yesterday, KU kindly told us about their collaboration with the World Wildlife Fund (WWF). Together, they are conducting a study to determine the ecological flow of Kaligandaki river, one of the largest rivers in Nepal. According to KU, the river’s ecosystem is particularly “complex as it includes aquatic invertebrates, flora, vertebrates, hydrology, geo-morphology, hydraulics, sociology-cultural and livelihood aspects.” The Associate Dean at KU’s School of Engineering wrote “We are deploying both traditional and modern technology to get the information from ground including UAVs. In this case we are using the DJI Phantoms,” which “reduced largely our field investigation time. The results are interesting and promising.” I look forward to sharing these results in a future blog post.


Lastly, KU’s Engineering Department has integrated the use of the robotics platforms directly into their courses, enabling Geomatics Engineering students to use the robots as part of their end-of-semester projects. In sum, KU has done truly outstanding work following our capacity building efforts and deserve extensive praise. (Alas, it seems that KLL has made little to no use of the aerial technologies or the software since our training 10 months ago).

Several months after the training in Nepal, we were approached by a British company that needed aerial surveys of specific areas for a project that the Nepal Government had contracted them to carry out. So they wanted to hire us for this project. We proposed instead that they hire our partners at Kathmandu Flying Labs since the latter are more than capable to carry out the surveys themselves. In other words, we actively drive business opportunities to Flying Labs partners. Helping to create local jobs and local businesses around robotics as a service is one of our key goals and the final phase of the Flying Labs framework.

So when we heard last week that USAID’s Global Development Lab was looking to hire a foreign company to carry out aerial surveys for a food security project in Nepal, we jumped on a call with USAID to let them know about the good work carried out by Kathmandu Flying Labs. We clearly communicated to our USAID colleagues that there are perfectly qualified Nepali pilots who can carry out the same aerial surveys. USAID’s Development Lab will be meeting with Kathmandu Flying Labs during their next visit in September.


On a related note, one of the participants who we trained in September was hired soon after by Build Change to support the organization’s shelter programs by producing Digital Surface Models (DSMs) from aerial images captured using DJI platforms. More recently, we heard from another student who emailed us with the following: “I had an opportunity to participate in the Humanitarian UAV Training mission in Nepal. It’s because of this training I was able learn how to fly drones and now I can conduct aerial Survey on my own with any hardware.  I would like to thank you and your team for the knowledge transfer sessions.”

This same student (who graduated from KU) added: “The workshop that your team did last time gave us the opportunity to learn how to fly and now we are handling some professional works along with major research. My question to you is ‘How can young graduates from developing countries like ours strengthen their capacity and keep up with their passion on working with technology like UAVs […]? The immediate concern for a graduate in Nepal is a simple job where he can make some money for him and prove to his family that he has done something in return for all the investments they have been doing upon him […]’.

This is one of several reasons why our approach at WeRobotics is not limited to scaling the positive impact of local humanitarian, development, environmental and public health projects. Our demand-driven Flying Labs model goes the extra (aeronautical) mile to deliberately create local jobs and businesses. Our Flying Labs partners want to make money off the skills and technologies they gain from WeRobotics. They want to take advantage of the new career opportunities afforded by these new AI-powered robotics solutions. And they want their efforts to be sustainable.

In Nepal, we are now interviewing the KU graduate who posed the question above because we’re looking to hire an outstanding and passionate Coordinator for Kathmandu Flying Labs. Indeed, there is much work to be done as we are returning to Nepal in coming months for three reasons: 1) Our local partners have asked us to provide them with the technology and training they need to carry out large scale mapping efforts using long-distance fixed-wing platforms; 2) A new local partner needs to create very high-resolution topographical maps of large priority areas for disaster risk reduction and planning efforts, which requires the use of a fixed-wing platform; 3) We need to meet with KU’s Business Incubation Center to explore partnership opportunities since we are keen to help incubate local businesses that offer robotics as a service in Nepal.

How to Democratize Humanitarian Robotics

Our world is experiencing an unprecedented shift from manually controlled technologies to increasingly intelligent and autonomous systems powered by artificial intelligence (AI). I believe that this radical shift in both efficiency and productivity can have significant positive social impact when it is channeled responsibly, locally and sustainably.


This is why my team and I founded WeRobotics, the only organization fully dedicated to accelerating and scaling the positive impact of humanitarian, development and environmental projects through the appropriate use of AI-powered robotics solutions. I’m thrilled to announce that the prestigious Rockefeller Foundation shares our vision—indeed, the Foundation has just awarded WeRobotics a start-up grant to take Humanitarian Robotics to the next level. We’re excited to leverage the positive power of robotics to help build a more resilient world in line with Rockefeller’s important vision.


Aerial Robotics (drones/UAVs) represent the first wave of robotics to impact humanitarian sectors by disrupting traditional modes of data collection and cargo delivery. Both timely data and the capacity to act on this data are integral to aid, development and environmental projects. This is why we are co-creating and co-hosting global network of “Flying Labs”; to transfer appropriate aerial robotics solutions and relevant skills to outstanding local partners in developing countries who need these the most.

Our local innovation labs also present unique opportunities for our Technology Partners—robotics companies and institutes. Indeed, our growing network of Flying Labs offer a multitude of geographical, environmental and social conditions for ethical social good projects and responsible field-testing; from high-altitude glaciers and remote archipelagos experiencing rapid climate change to dense urban environments in the tropics subject to intense flooding and endangered ecosystems facing cascading environmental risks.

The Labs also provide our Technology Partners with direct access to local knowledge, talent and markets, and in turn provide local companies and entrepreneurs with facilitated access to novel robotics solutions. In the process, our local partners become experts in different aspects of robotics, enabling them to become service providers and drive new growth through local start-up’s and companies. The Labs thus seek to offer robotics-as-a-service across multiple local sectors. As such, the Labs follow a demand-driven social entrepreneurship model designed to catalyze local businesses while nurturing learning and innovation.

Of course, there’s more to robotics than just aerial robotics. This is why we’re also exploring the use of AI-powered terrestrial and maritime robotics for data collection and cargo delivery. We’ll add these solutions to our portfolio as they become more accessible in the future. In the meantime, sincerest thanks to the Rockefeller Foundation for their trust and invaluable support. Big thanks also to our outstanding Board of Directors and to key colleagues for their essential feed-back and guidance.

Humanitarian Cargo Delivery via Aerial Robotics is Not Science Fiction (Updated)

I had the opportunity to visit Zipline’s field-testing site in San Francisco last year after the company participated in an Experts Meeting on Humanitarian UAVs (Aerial Robotics) that I co-organized at MIT. The company has finally just gone public about their good work in Rwanda, so I’m at last able to blog about it on iRevolutions. When I write “finally”, this is not meant to be a complaint; in fact, one aspect that really drew me to Zipline in the first place is the team’s genuine down-to-earth, no-hype mantra. So, I use the word finally since I now finally have public evidence to backup many conversations I’ve had with humanitarian partners on the topic of cargo delivery via aerial robotics.

Zip Delivery

As I had signed an NDA, I was (and still am) only allowed to discuss information that is public, which was basically nothing until today. So below is a summary of what is at last publicly known about Zipline’s pioneering aerial robotics efforts in Rwanda. I’ve also added videos at the end.


  • Zipline’s Mission: to deliver critical medical products to health centers and hospitals that are either difficult or impossible to reach via traditional modes of transportation
  • Zipline Fleet: 15 aerial robotics platforms (UAVs) in Rwanda.
  • Aerial Robotics platform: Fixed-wing.
  • Weight of each platform: 10-kg.
  • Power: Battery-operated twin-electric motors.
  • Payload capacity: up to 1.5kg.
  • Cargo: Blood and essential medicines (small vials) to begin with. Eventually cargo will extend to lifesaving vaccines, treatments for HIV/AIDS, malaria, tuberculosis, etc.
  • Range: Up to 120 km.
  • Flight Plans: Pre-programmed and monitored on the ground via tablets. Individual plans are stored on SIM cards.









  • Flight Navigation: GPS using the country’s cellular network.
  • Launch Mechanism: Via catapult.
  • Maximum Speed: Around 100 km/hour.
  • Landings: Zipline’s aerial robot does not require a runway.
  • Delivery Mechanism: Fully autonomous, low altitude drop via simple paper parachute. Onboard computers determine appropriate parameters (taking into account winds, etc) to ensure that the cargo accurately lands on it’s dedicated delivery site called a “mailbox”.
  • Delivery Sites: Dedicated drop sites at 21 health facilities that can carry out blood transfusions. These cover more than half of Rwanda.

Screen Shot 2016-04-05 at 4.22.02 PM










  • Takeoff Sites: Modified shipping containers located next to existing medical warehouses.
  • Delivery Time: Each cargo is delivered within 1 hour. The aerial robot takes about 1/2 hour reach a delivery site.
  • Flight Frequency: Eventually up to 150 flights per day.
  • Weather: Fixed-wings can operate in ~50km/hour winds.
  • Regulatory Approval: Direct agreements already secured with the Government of Rwanda and country’s Civil Aviation Authority.


Think Global, Fly Local: The Future of Aerial Robotics for Disaster Response

First responders during disasters are not the United Nations or the Red Cross. The real first responders, by definition, are the local communities; always have been, always will be. So the question is: can robotics empower local communities to respond and recover both faster and better? I believe the answer is Yes.

But lets look at the alternative. As we’ve seen from recent disasters, the majority of teams that deploy with aerial robotics (UAVs) do so from the US, Europe and Australia. The mobilization costs involved in flying a professional team across the world—not to mention their robotics equipment—is not insignificant. And this doesn’t even include the hotel costs for a multi-person team over the course of a mission. When you factor in these costs on top of the consulting fees owed to professional international robotics teams, then of course the use of aerial robotics versus space robotics (satellites) becomes harder to justify.

There is also an important time factor. The time it takes for international teams to obtain the necessary export/import permits and customs clearance can be highly unpredictable. More than one international UAV team that (self) deployed to Nepal after the tragic 2015 Earthquake had their robotics platforms held up in customs for days. And of course there’s the question of getting regulatory approval for robotics flights. Lastly, international teams (especially companies and start-up’s) may have little to no prior experience working in the country they’re deploying to; they may not know the culture or speak the language. This too creates friction and can slow down a humanitarian robotics mission.

What if you had fully trained teams on the ground already? Not an international team, but a local expert robotics team that obviously speaks the local language, understands local customs and already has a relationship with the country’s Civil Aviation Authority. A local team does not need to waste time with export/import permits or customs clearance; doesn’t need expensive international flights or weeks’ worth of hotel accommodations. They’re on site, and ready to deploy at a moment’s notice. Not only would this response be faster, it would be orders of magnitudes cheaper and more sustainable to carry through to the recovery and reconstruction phase.

In sum, we need to co-create local Flying Labs with local partners including universities, NGOs, companies and government partners. Not only would these Labs be far more agile and rapid vis-a-vis disaster response efforts, they would also be far more sustainable and their impact more scalable than deploying international robotics teams. This is one of the main reasons why my team and I at WeRobotics are looking to co-create and connect a number of Flying Labs in disaster prone countries across Asia, Africa and Latin America. With these Flying Labs in place, the cost of rapidly acquiring high quality aerial imagery will fall significantly. Think Global, Fly Local.
