A robot (14) capable of moving against gravity uses at least one vacuum cup assembly (15) having a port (10) for applying a lubricant on the working surface (13) so the cup (1) may slide on the surface (13) as the robot (14) is maneuvered with the aid of powered wheels (16). The wheels (60) and vacuum cup assembly (15) are coordinated to move on varied surfaces (13). The robot module (19, 20, 21) may be equipped with various task-performing assemblies (80, 81, 82), and may be employed in caravans, trains, or separately in swarms. The vacuum cup assemblies (15) include a pair of springs (62) working against each other to provide stability and flexibility at the point of attachment to the body (14) of the robot (14).
