Abstract
The present disclosure provides an obstacle avoidance method and system for a robot having ranging sensors as well as a robot using the same. The method includes: obtaining detection data collected by the plurality of ranging sensors; obtaining a current position of the robot based on the collected detection data; determining whether historical detection data corresponding to the current position has been stored; planning a movement path of the robot based on the collected detection data and the historical detection data and generating movement path information of the movement path, if the historical detection data corresponding to the current position has been stored; and controlling the robot to move along an obstacle-free path based on the movement path information. The present disclosure can effectively break through the limitation of the sensor technology, reduce the detection blind zone, and effectively improve the obstacle avoidance efficiency of a robot.
