Air Walker

Description

A robot that defies gravity? That’s what you get with Air-Walker from Thames & Kosmos, a four-legged bot that uses an ingenious system of suction cups and pumps to crawl along smooth, vertical surfaces like windows. Your Air-Walker 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 build four other models with the same components and learn how suction and mechanical devices can be used in different real-world applications. A vacuum-suction machine sticks to and lifts flat panels, while a robot with just two suction cups rotates around a central pivot point.
