Method and system for solving abnormal pause motion of robot in narrow channel

The invention discloses a method and system for solving abnormal motion pause of a robot in a narrow channel, and the method comprises the steps: controlling the robot to stop advancing and wait when an obstacle is detected in a set range of the advancing direction; if entering the narrow channel and the channel is blocked, obtaining the width of the narrow channel according to the width of the first channel and the width of the second channel, and planning a central path of the first channel based on a planning algorithm and the width of the narrow channel; based on the first channel center path, planning a first narrow channel exit path through a dijkstra planning algorithm; the robot exits from the narrow channel and returns to a preset path according to the first narrow channel exit path; and setting the narrow channel as a dangerous area and storing the dangerous area into a database of the robot. The technical problem that in the prior art, when a robot carries out obstacle avoidance planning in a compl
