Abstract

With the rapid development of science and technology and the impact of the novel coronavirus epidemic in recent years, medical delivery robots have gradually appeared in major medical institutions. However, traditional medical delivery robots have local optimal solution problems and target unreachable problems when using artificial potential field algorithms for path planning. Therefore, for the local optimal solution problem, this paper proposed a method of designing virtual target points to rescue the robot from the local optimal state. It introduced the target distance function into obstacle repulsion potential field function to limit obstacle repulsion, to solve the problem of target unreachable. Finally, it compared the proposed method with the traditional algorithm in a variety of complex environments. The results show that the improved algorithm can solve the local optimal solution and target unreachable problems existing in the traditional algorithm, and the efficiency of the algorithm is also increased by 5%~9% and can be effectively applied to practical scenarios.
