RISCuer: A Reliable Multi-UAV Search and Rescue Testbed
share
We present the RISC Lab multi-agent testbed for reliable search and rescue and aerial transport in outdoor environments. The system consists of a team of three multi-rotor Unmanned Aerial Vehicles (UAVs), which are capable of autonomously searching, picking, and transporting randomly distributed objects in an outdoor field. The method involves vision based object detection and localization, passive aerial grasping with our novel design, GPS based UAV navigation, and safe release of the objects at the drop zone. Our cooperative strategy ensures safe spatial separation between UAVs at all times and we prevent any conflicts at the drop zone using communication enabled consensus. All computation is performed onboard each UAV. We describe the complete software and hardware architecture for the system and demonstrate its reliable performance using comprehensive outdoor experiments and by comparing our results with some recent, similar works.
