Gigo Air-Walker

Experiment with the physics of air pressure and suction!

A robot that defies gravity? This is the robot you get with the Air-Walker, a four-legged robot that uses an intelligent system of suction cups and pumps to crawl along a smooth surface like windows.

The robot can crawl in a straight line, to the left, or to the right, while a special mechanism makes the robot's head move back and forth as its body moves forward.

You can also construct four other models with the same pieces and learn how suction and mechanical devices can be used in different real-world applications.

A vacuum suction machine sticks and lifts the suction cups, while the robot with just two suction cups rotates around a central pivot point.
