Abstract

Disclosed is a biped robot and multi-configuration robot capable of being spliced autonomously, and a control method of the multi-configuration robot. The biped robot comprises a torso, arms, legs, a tolerance docking sleeve, and a torso docking device. The arms are correspondingly arranged at the left and right sides of the torso, and two legs are arranged at the lower side of the torso. The tolerance docking sleeve is movably arranged at the rear side of the torso through a base, and the torso docking device is fixed to the front side of the torso. Single biped robots in the present disclosure can form a multi-configuration legged combined body in a self-organization and reconstruction mode so as to achieve bipedal, quadrupedal, hexapodal and other multi-legged configurations. The motion stability and the load capacity of the legged robot are improved through the splicing combination of the modular legged robots.
