Abstract: Aiming at the defects of ordinary omnidirectional wheel which is easy to slip and shake due to small contact area, the omnidirectional steering wheel moving platform control system is designed. The system uses STM32F407ZET6 single chip microcomputer as the main control chip, and uses four groups of steering wheels to form the whole mobile platform. Each group of steering wheels is composed of two motors and an absolute encoder, and controls eight motors of the mobile platform through CAN bus. The whole system determines the self attitude and angle of the omnidirectional steering wheel mobile platform through the gyroscope, uses serial communication to read the whole field positioning data and process the data, obtains the analog voltage signal output by the laser ranging sensor through AD sampling, and obtains the position data after the voltage signal is processed by the microcontroller,forms a closed loop control system through the PID algorithm, and uses the remote controller to control the mobile platform.
