Abstract
An escaping method of a cleaning robot includes: when the cleaning robot encounters an obstacle and turns around while performing cleaning along an edge of a first surface medium area, in response to a surface medium change signal from the surface medium sensor indicates that a second surface medium area is detected, searching an established room map to determine whether the second surface medium area exists in the room map; if the second surface medium area exists, determining whether a route bypassing the second surface medium area exists based on the room map and a boundary of the second surface medium area in the room map; if the route exists, controlling the cleaning robot to travel along the route to bypass the second surface medium area; and if the route does not exist, controlling the cleaning robot to return along a cleaned route to bypass the second surface medium area.
