    To control the motion of a mobile robot in a partially-known environment, a hybrid method is used to fully utilize the advantages of both global and local strategies. The pre-acquired knowledge of the environment is memorized. It is useful for generating a global route and also for comparison between the real scene and the memorized one. If the sensors data in both scenes are the same, the navigat... View full abstract»
