Drones & «Sense & Avoid»: Researchers at the University of Zurich have developed a new system that lets drones dodge high-speed obstacles

This Drone Can Play Dodgeball – And Win
Using a novel type of cameras, researchers from the University of Zurich have demonstrated a flying robot that can detect and avoid fast-moving objects. A step towards drones that can fly faster in harsh environments, accomplishing more in less time.
Drones can do many things, but avoiding obstacles is not their strongest suit yet – especially when they move quickly. Although many flying robots are equipped with cameras that can detect obstacles, it typically takes from 20 to 40 milliseconds for the drone to process the image and react. It may seem quick, but it is not enough to avoid a bird or another drone, or even a static obstacle when the drone itself is flying at high speed. This can be a problem when drones are used in unpredictable environments, or when there are many of them flying in the same area.
Reaction of a few milliseconds
In order to solve this problem, researchers at the University of Zurich have equipped a quadcopter (a drone with four propellers) with special cameras and algorithms that reduced its reaction time down to a few milliseconds – enough to avoid a ball thrown at it from a short distance. The results, published in the journal Science Robotics, can make drones more effective in situations such as the aftermath of a natural disaster.
“For search and rescue applications, such as after an earthquake, time is very critical, so we need drones that can navigate as fast as possible in order to accomplish more within their limited battery life,” explains Davide Scaramuzza, who leads the Robotics and Perception Group at the University of Zurich as well as the NCCR Robotics Search and Rescue Grand Challenge. “However, by navigating fast drones are also more exposed to the risk of colliding with obstacles, and even more if these are moving. We realized that a novel type of camera, called Event Camera, are a perfect fit for this purpose”.
Event cameras have smart pixels
Traditional video cameras, such as the ones found in every smartphone, work by regularly taking snapshots of the whole scene. This is done by exposing the pixels of the image all at the same time. This way, though, a moving object can only be detected after all the pixels have been analysed by the on-board computer. Event cameras, on the other hand, have smart pixels that work independently of each other. The pixels that detect no changes remain silent, while the ones that see a change in light intensity immediately send out the information. This means that only a tiny fraction of the all pixels of the image will need to be processed by the onboard computer, therefore speeding up the computation a lot.
Event cameras are a recent innovation, and existing object-detection algorithms for drones do not work well with them. So the researchers had to invent their own algorithms that collect all the events recorded by the camera over a very short time, then subtracts the effect of the drone’s own movement – which typically account for most of the changes in what the camera sees.
Only 3.5 milliseconds to detect incoming objects
Scaramuzza and his team first tested the cameras and algorithms alone. They threw objects of various shapes and sizes towards the camera, and measured how efficient the algorithm was in detecting them. The success rate varied between 81 and 97 per cent, depending on the size of the object and the distance of the throw, and the system only took 3.5 milliseconds to detect incoming objects.
Then the most serious test began: putting cameras on an actual drone, flying it both indoor and outdoor and throwing objects directly at it. The drone was able to avoid the objects – including a ball thrown from a three-meter distance and travelling at 10 meters per second – more than 90 per cent of the time. When the drone “knew” the size of the object in advance, one camera was enough. When, instead, it had to face objects of varying size, two cameras were used to give it stereoscopic vision.
According to Scaramuzza, these results show that event cameras can increase the speed at which drones can navigate by up to ten times, thus expanding their possible applications. “One day drones will be used for a large variety of applications, such as delivery of goods, transportation of people, aerial filmography and, of course, search and rescue,” he says. “But enabling robots to perceive and make decision faster can be a game changer for also for other domains where reliably detecting incoming obstacles plays a crucial role, such as automotive, good delivery, transportation, mining, and remote inspection with robots”.
Nearly as reliable as human pilots
In the future, the team aims to test this system on an even more agile quadrotor. “Our ultimate goal is to make one day autonomous drones navigate as good as human drone pilots. Currently, in all search and rescue applications where drones are involved, the human is actually in control. If we could have autonomous drones navigate as reliable as human pilots we would then be able to use them for missions that fall beyond line of sight or beyond the reach of the remote control,” says Davide Falanga, the PhD student who is the primary author of the article.
The work was funded by the Swiss National Science Foundation through the National Center of Competence in Research (NCCR) Robotics.

Mitsubishi Aircraft Makes Maiden Flight of Mitsubishi SpaceJet Flight Test Vehicle 10 (FTV10)
press release
https://www.mitsubishiaircraft.com/latest/maiden-flight-of-mitsubishi-spacejet-flight-test-vehicle-10
Mitsubishi Aircraft Corporation, a MHI Group company, announced that it has completed the maiden flight of Flight Test Vehicle 10 (FTV10), the first Mitsubishi SpaceJet M90 in final, certifiable baseline configuration.
FTV10 took off at 14:53 (JST) from the Prefectural Nagoya Airport and conducted basic aircraft performance tests in normal operating conditions over the Pacific Ocean. After approximately two hours of flight, the aircraft returned to Nagoya at 16:40 (JST). With the completion of FTV10’s first flight, Mitsubishi Aircraft Corporation is prepared to enter the final phase of certification flight testing for the SpaceJet M90, the first commercial jet manufactured in Japan.
"I am very pleased that FTV10, which was handed over from Mitsubishi Heavy Industries in January this year, successfully conducted its first flight today," Hisakazu Mizutani, President of Mitsubishi Aircraft said. “I would like to express my deepest gratitude to all those who are continuously supporting the program. We are excited for this latest step in the certification of the Mitsubishi SpaceJet M90."
“Today’s announcement is especially encouraging, as it marks the start of certification flight testing for the first SpaceJet M90 in final, certifiable configuration,” added Alex Bellamy, Mitsubishi Aircraft’s Chief Development Officer. “We are all proud of this latest accomplishment, which reflects the hard work of a dedicated team, the culmination of an organizational transformation and all of the engineering changes made since 2016. We look forward to continuing our progress toward commercial certification of the M90 program.”
Hiroyoshi Takase, a captain aboard FTV10’s maiden flight, remarked, “Today’s flight test was conducted smoothly and according to plan. The aircraft delivered on expectations and handled just as I anticipated.”
In coming weeks Mitsubishi Aircraft plans to continue flight tests on FTV10 in Nagoya, as well as prepare for the ferry flight to Moses Lake Flight Test Center (MFC) to join the remainder of the Mitsubishi SpaceJet M90 test fleet for the final phase of type certification flight test.
