Edd GentWeaving through dense woods is a challenge for even the smartest drone. Trying to do it as part of a swarm is orders of magnitude harder.
But researchers have now cracked the code.The approach builds on a single-drone navigation technique, which rapidly maps routes around obstacles as they come within view using only the drone’s onboard camera and computer.
The team, which was also behind the earlier strategy, adapted it for swarms by getting drones to broadcast their trajectories over a wireless network.
