WINDOW WIPING ROBOT

PURPOSE: To provide a window wiping robot which enables an adsorption mechanism to be a simple support structure without requiring a large suction force for a vacuum pad. CONSTITUTION: A main drive ring G which is connected to a first bearing member 33b through a first arm 32b is fixed on a main rotating shaft 31b to be rotated by driving of main motors M arranged at four corners of a frame body 16. The first bearing member 33b supports a first rotating shaft 36b spline engaged rotatably with a subdrive ring (g) and is connected to a second bearing member 35b through a second arm 34b. Moreover, the second bearing member 35b supports a second rotating shaft 37b rotatably. The first and second rotating shafts are movable axially and vacuum pads B1 and B2 are mounted respectively at the lower end parts thereof.
