The invention discloses a robot capable of rotating in multiple directions. The robot capable of rotating in multiple directions comprises a cross arm. A groove is formed in the cross arm. A first through hole and a second through hole are formed in the bottom inner wall of the groove. The first through hole is located on one side of the second through hole. Vertical plates are symmetrically welded to the top inner wall and the bottom inner wall of the groove. An upright plate is welded to the top inner wall and the bottom inner wall of the groove. The robot capable of rotating in multiple direction is simple in structure, a driving motor can drive a left mounting plate and a right mounting plate to move horizontally, a cylinder enables two circular rubber strips to squeeze a disc after the length is adjusted, then the length of a mechanical arm is adjusted so that workpieces at different positions can be polished, and the polishing efficiency is improved; and after the length is adjusted, the two circular rubber strips can firmly clamp the disc to prevent a lead screw from rotating, so that the stability of the mechanical arm is ensured, and using is convenient.
