Design of Automatic Cruise Car Based on UWB Positioning

Aiming at the problems of traditional tracking, such as difficulty in deployment, low flexibility and high cost, this paper proposes and designs an automatic cruising car based on UWB positioning technology. The car adopts the Raspberry Pi 3B module as the core control unit, obtains the position through the UWB module, acquires the azimuth of the vehicle through the MPU9250 module, detects the obstacles in front through the ultrasonic sensor, and uses the incremental PID control algorithm to track the specified path. Different from the traditional way of laying magnetic needles and printing guide lines, position coordinate information is introduced in this design, and a series of coordinate points are used as the guiding path of the trolley. Tests show that the designed car can complete the function of automatic cruising according to the specified path, which has certain practical application value.
