The invention is suitable for the field of a robot and provides a method and a device for adjusting a robot path. The method comprises the following steps: acquiring preset path information of a robot; acquiring the current position information of the robot; generating virtual paths around the robot for 360 degrees by taking the robot as a center; and selecting one virtual path from the generated virtual paths as a new driving route, on the basis of the preset path information and the current position information. According to the method, the obstacle avoidance flexibility can be promoted.
