A robot including a frame (10) with wheels (12, 14) able to move over a highly magnetically permeable support surface and at least one permanent magnet (30) able to interact magnetically with, and couple the robot to, the surface. The permanent magnet (30) is positioned so that one pole grazes the surface and is free to oscillate so that the pole always faces the surface and is a minimum distance from it. |
