ABSTRACT

This paper describes the research and implementation process of automatic tracking system based on ultra-wideband positioning, including hardware architecture and software control logic. The paper analyzes the influence of various internal factors such as positioning data jitter, suitcase's own inertia, data arrival delay and hardware drive system limitations on the smoothness and stability of the suitcase following the user process, and considering external factors such as the user's walking speed, etc. Improved the control process of changing the speed and steering, and propose an optimized follow-up algorithm. The experimental results show that the optimized following algorithm can greatly improve the stability of the self-walking follow-up process and reduce the rolloves and slipping.
