In this video, three ground robots — two A1 quadrupeds and one HSR mobile platform — sweep an environment quickly in search of a missing volleyball ball. They achieve this capability by employing online path planning and heterogeneous clustering to accommodate for the different speeds and fields of view of each robot. The algorithm supports up to 50 robot/vehicle search and is robust to robot/vehicle failures by re-planning at runtime. This technology is geared towards tasks such as emergency response where people could be missing during a fire or flood.
