Watch a swarm of underwater drones hunt and surround a boat

The swarm consists of SwarmDivers, small rocket-shaped vehicles, that can work cooperatively to carry out impossible feats for single robot submarines, as shown in a new video. The SwarmDiver drones were unveiled last week by Aquabotix, a firm based in Australia. While many autonomous underwater vehicles are already in use, Aquabotix says their SwarmDivers can work as a group, with one operator controlling the entire swarm via a simple interface.
