MAGNETICALLY ATTRACTED ROBOT

PURPOSE:To automatize an operation such as removal of rusts on a wall surface, by providing magnets for supporting a frame on a surface of a magnetic structure. CONSTITUTION:Of the frame, left and right frames 11c, 11d are provided with guide grooves 21 in the interior thereof, and ball nuts 23 fixed to both ends of a rod body 13 are slidably fitted into the grooves 23. The rod body 13 is provided with a guide groove 26 along it, and a ball nut 27 connected to a traveling part 14 is slidably fitted into the groove 26. A screw shaft 28 axially supported along the rod body 13 is engaged with a threaded hole of the ball but 27, and when the screw shaft 28 is rotated by a driving motor 29, the traveling part 14 is moved along the rod body 13. Since the traveling part 14 can be moved in longitudinal and transverse directions to cover a tetragonal area, the surface 8 onto which the robot is to be attracted can be covered in a belt from by sequentially moving the robot in a transverse direction.
