Climb@Tron climbing robots scoff at the forces of gravity as they use powerful suction cup systems to climb up smooth surfaces including windows, mirrors, metal file cabinets, and plexiglass. Endorsed by the Science Museum, London as a line that raises "questions about forces, gravity, friction, and lets children experience some everyday 'invisible science', Climb@Tron robots are sure to delight. Watch them as they plod straight up your mirror, stride across your computer screen, work their way down your sliding glass door. Powerful piston driven suction cups snap into place.
