Problems solved by technology

The existing firefly swarm algorithm has high computational efficiency, small memory overhead, few parameters to adjust, and is simple and easy to implement. However, the disturbance coefficient α in the existing firefly algorithm is usually fixed, which is critical for the search of the algorithm. Flawed, like other random search algorithms also suffer from premature convergence

Abstract

The invention discloses an automatic path programming method of a mobile robot, and the mobile robot using the method. The method comprises the following steps of: collecting environment information; according to the collected environment information, carrying out modeling on an area in which path programming of the mobile robot is carried out so as to construct a two-dimensional plane coordinate map, and determining a start point, a stop point and coordinate positions of obstacles; based on the two-dimensional plane coordinate map, carrying out path optimization on the paths from the start point to the stop point by means of population initialization based on a Sobol sequence and a firefly algorithm of a dynamic adjustment disturbance coefficient update population, and programming the optimized path to for driving in the two-dimensional plane coordinate map; and according to the optimized path after programming, driving the mobile robot to move. According to the invention, the problem that an existing firefly algorithm is insufficient in convergence performance is overcome, the mobile robot is enabled to rapidly, accurately and automatically program the path, and the path programming capability of the mobile robot is improved.
