In biology, a swarm is a collection of individuals that manifest complex behavior without a leader calling the shots. Imagine birds spontaneously gathering on a single tree, only to lift off en masse moments later. Scientists have applied swarm intelligence to driving robots, but they now have the processing power and sensing capability to apply it to flying ones too.
To achieve a swarm, scientists program each unit with a set of simple rules. For example: Maintain constant separation, steer in the same direction, and always move toward the center of the swarm. The result is a mass of individuals that can move as a group. Scientists at Grasp recently used a UAV swarm to pick up and haul heavy objects. Continue reading
