Soon your drone can avoid collisions using radar

The system consists of a mountable hardware band that scans up to 200 meters in every direction along with software that automatically avoids detected obstacles. If objects larger than a meter enter that radius, the radar system will detect it and automatically move the drone to avoid a collision. Arbe Robotics claims that its solution only uses 5 percent battery life throughout the flight. Obviously, this is for a civilian solution detecting slow-moving obstacles. DARPA has been innovating a collision avoidance system for drones to dodge speedy things like small aircraft and other drones.
