Abstract
A robotic obstacle-crossing device mainly includes a wheel body and an obstacle-crossing body, wherein the wheel body includes a wheel part, a first obstacle-crossing part and a second obstacle-crossing part. When the sweeping robot tilts, the plurality of first recessed portions and the plurality of second recessed portions provided on the periphery of the first obstacle-crossing part and the second obstacle-crossing part provide a climbing function. In addition, when the sweeping robot encounters obstacles or steps, the obstacle-crossing body can provide robot the function of the obstacle-crossing or climbing, thereby reducing the number of situations when the sweeping robot is trapped or unable to effectively climb upon encountering an obstacle or a steep road surface.
