Abstract
A grinding robot has a grinding device for grinding a surface using a grinding means, a movement device for moving the grinding device over the surface, and a suction device for suctioning a grinding robot housing onto the surface. The movement device has two or more suction lifter elements which are suctioned onto the surface by negative pressure. Each suction lifter element is supported on the grinding robot housing via a rotary drive device and the grinding robot housing can thereby be set into a rotational element is configured as a grinding plate. The grinding plate has suction openings for movement relative to a suction lifter element suctioned onto the surface. A suction lifter suctioning the grinding plate onto the surface. The grinding disc fastened to the grinding plate has an opening, which is arranged in an at least partially overlapping manner with the suction opening in the grinding plate.
