In the multi-robots system , it's important for a robot to acquire adaptive navigation rules for reaching the goal and avoiding other robots and obstacles and in the real-time environment.An efficient approach to collision-avoidance in multi-robots system is suggested .It is based on velocity information of moving objects and the distances between the robots and the obstacles in three specified directions and makes the robot navigate adaptively without collision with each other in a complicated situation.The effectiveness of algorithm is proved by the several simple examples in the physical world.
