Kids can build a mighty robotic bug that defies gravity to crawl up, down, and all around windows with ease! This hands-on mechanic construction kit brings engineering and physics to life. Assemble the robot to learn how its gears, motor, battery, and switch all work together. This multi-legged machine uses suction cups to walk around on smooth vertical surfaces. Kids can experiment to see what else it can climb! Kids can build a mighty robotic bug that defies gravity to crawl up, down, and all around windows with ease!
