In a specific scene, a group of robots is required, which can start from a certain place, reach a designated location, take high objects, and then safely transport them to a designated location. Based on the research status at home and abroad, this paper proposes a software and hardware system design scheme, which has been verified by practice, can not only accurately complete the collaborative retrieval task, but also safely deliver to the destination in a short time. The robot design in this paper needs ingenious mechanical structure design and good operation cooperation of the robot.
