Abstract

Embodiments of the present disclosure provide an autonomous mobile robot and a walking method thereof. The autonomous mobile robot includes a machine body, a driving wheel assembly and an obstacle crossing assembly. The driving wheel assembly is rotatably arranged on the machine body through a first rotating shaft. The driving wheel assembly includes a driving wheel. When the driving wheel moves from a first position to a second position relative to the machine body, the obstacle crossing assembly applies a force to the driving wheel assembly to make a change amplitude of positive pressure between the driving wheel and a traveling surface less than or equal to a set threshold value.
