Build a mighty robotic bug that defies gravity
Build a mighty robotic bug that defies gravity to crawl up, down, and all around windows with ease! This motorised, multi-legged machine uses an ingenious system of suction cups to walk on smooth vertical surfaces like windows and glossy panels. Assemble the robot to learn about its inner mechanisms, including gears and an electric circuit complete with motor, battery, and switch. Then experiment to see which types of surfaces your Gravity Bug can climb best. Read about how suction cups work and how this robot climbs.
