This astonishing wall-climbing robot has a motorized air suction system that enables it to walk vertically up and down perfectly smooth surfaces, like glass, plastic, whiteboards, and glossy laminates. The battery-powered motor drives an innovative gear system that produces a rotating motion making the legs move back and forth and up and down, mimicking a real gecko. With this kit you can build six other models and conduct experiments with suction to learn about air pressure.
