The application relates to the technical field of robots, and discloses a robot guiding method based on a hierarchical guiding architecture, a robot guiding device and a storage medium. The method comprises the following steps: adopting a global path planning algorithm to plan a global path from a starting point to an ending point in a search space; planning a local path by a dynamic window method, and generating the local path; taking a reference point position on the local path as a preset pose of an end effector; acquiring a direction deviation between an actual pose and the preset pose of the end effector; and when the direction deviation between the actual pose and the preset pose of the end effector is greater than a preset value, outputting a traction force for suppressing the direction deviation by the end effector.
