Abstract: An intelligent mobile device and a control method therefore are described. The method includes: acquiring, when the intelligent mobile apparatus is trap, first ground medium attribute information of a trapping region, where the first ground medium attribute information includes ground medium attribute information of the trapping region; and controlling, if the first ground medium attribute information matches target ground medium attribute information, the intelligent mobile apparatus to leave the trapping region and re-enter the trapping region in a direction different from a direction in which the intelligent mobile apparatus enters the trapping region.

Abstract: The present disclosure provides an obstacle avoidance method and apparatus for a self-walking device, a medium, and an electronic device. In the present disclosure, current feature information and historical feature information which have spatial meanings are analyzed by using spatial information of the machine body, and a new travel route is re-planned. A travel route suitable for the self-walking device is acquired after evaluation based on the spatial information. Limitations of the travel route planning which solely depends on a distance from the obstacle detected at the same height are avoided, and the route planning effectiveness is improved.
