Going up. Build an adorable robotic gecko that defies gravity to crawl up, down, and all around smooth vertical surfaces. As you assemble this motorized, multi-legged machine with suction cup feet and an innovative gear system, you'll learn about its inner mechanisms, including an electric circuit complete with motor, battery, and switch. Then experiment to see which types of surfaces your Geckobot can climb best and read about how suction cups work and how this robot climbs. This hands-on construction kit brings engineering and physics to life as it demonstrates the power of air pressure at work. A 16-page, full-color manual guides your model building with step-by-step illustrated instructions.
