| Abstract: | By using the laser scanner for sensing the surrounding environment, an obstacle avoidance strategy of mobile robots under dynamic environments was designed. Based on the real-time environment information of the laser scanner, the dynamic and static obstacles were detected and the chain table of the obstacles was established. The obstacle avoidance under dynamic environments was achieved by the tight integration of the reactive obstacle avoidance module in the low layer and the dynamic obstacle avoidance module in the higher layer. The distributed method of software design improved the realtime ability of the system. The validity of the strategy was validated by the experiments on the mobile robot MORCS-1. |
