The astonishing wall walking robot has a motorized air suction system that makes it able to walk directly vertical on a smooth surface. The battery driven motor gear function creates a rotation that makes legs move like on a real Gecko, and the suction pumps make the feet able to stick and release on a surface at the right moment.
While walking tail part moves from side to side and makes the robot look very alive. You can build other animal designs on the same function and 6 alternative experiments with suction and learn about Bionic movements. Requires 2 AAA/LR03 batteries-not included.
