Coordination of Robot Teams Over Long Distances: From Georgia Tech to Tokyo Tech and Back-An 11,000-km Multirobot Experiment

One reason why multirobot systems are preferred, in some contexts, over their single-robot counterparts is that they admit a larger spatial footprint. With multiple robots, it is possible to span a large area, which is desirable in applications such as search and rescue, environmental monitoring, and perimeter patrol [1]. However, as interrobot distances grow, so do the communication delays experienced among the robots, making precise, coordinated control hard to achieve [2]-[5].
