Abstract
Provided is an autonomous mobile robot, includes a cover, a base and a pressure sensor assembly; the cover includes a top plate and a side plate that are integrally arranged, a connecting portion is formed between the top plate and the side plate, and the connecting portion is at least partially higher than the top plate; the base is arranged below the top plate; and the pressure sensor assembly is arranged in a manner of facing the side plate. The impact of the traditional autonomous mobile robot using a floating bump plate on the positioning accuracy of an optical component may be avoided and the reliability of the autonomous mobile robot during the movement is improved.
