Abstract: In order to provide a simulation and test platform for the performance test, control algorithm analysis and operation training of underwater robot, a hardware-in-the-loop simulation system based on Unity3D is developed, which consists of a ground control terminal, a robot body and a three-dimensional simulation system. The system uses the same ground control terminal as the unified command input source of the three-dimensional simulation system and robot control system, and realizes the synchronization of the virtual object and robot body, real-time monitoring and parameters adjustment to the system. The position of the robot is collected by multiocular vision technology, and Kalman filtering processing is carried out on sensor data. The robot motion simulation results show that the actual motion path of the robot is basically the same as the simulation planning path, and the hardware-in-the-loop simulation system has good dynamic response and control system synchronization.
