Centroid adjusting device and quadruped robot

The utility model discloses a mass center adjusting device and a quadruped robot, and belongs to the technical field of robots. Comprising a guide rail, a base and a load protection support. The guide rails are arranged on the two sides of the quadruped robot in the width direction correspondingly, and the guide rails are symmetrically arranged in the length direction of the quadruped robot. The two sides, in the width direction, of the base are connected with the sliding blocks correspondingly, and the base is in sliding connection with the guide rails through the sliding blocks and slides in the length direction of the guide rails. The load protection supports are arranged on the two sides, in the width direction, of the base correspondingly and oppositely, and the load protection supports are located on the top of the base. The position of the load can be flexibly adjusted until the mass center of the quadruped robot is stable, and unbalance of the robot is prevented; the problem that the mass center of th
