[0002] Currently, in the library robot sorting system, there are two main ways to connect the book return machine and the sorting robot: 1. The top surface of the book return belt of the book return machine is at the same height as the top surface of the robot tray. The robot stops and waits at the end of the book return belt. The book return belt rotates to send the books to the robot's book receiving tray, and the background notifies the robot to leave for the destination; 2.
