ResQbot is a proof-of-concept mobile rescue robot that has been designed for casualty extraction. This robot is a stretcher type casualty extraction robot platform comprising a motorised stretcher bed conveyor attached to a differential-drive mobile base. This robot is a stretcher-type mobile rescue robot designed to safely load a casualty using the loco-manipulation approach — using combination of the robot’s wheeled locomotion and the active pulling from the belt conveyor mechanism to load a casualty. The loco-manipulation process allows the robot to load the casualty while ensuring key safety thresholds are adhered to and avoids potential causes of additional injury to the casualty, such as head, neck or spinal cord injuries. The stretcher bed conveyor of this robot is also equipped with a stretcher strap mechanism to safely secure the casualty during the transportation. ResQbot is also equipped with perception devices, including an RGB-D camera and stereo camera rigs, that provides the perceptive feedback required during the operation. These perception devices are also designed to further enable ResQbot to perform autonomous casualty detection.

HiDO-MPC for Autonomous Casualty Extraction
In this paper, we propose a Hierarchical Decomposed-Objective based Model Predictive Control (HiDO-MPC) method for safely approaching and manoeuvring around the casualty. At every time step, the controller evaluates this hierarchical decomposed objective and generates the optimal control decision in order to safely prepare for casualty extraction.
