How To Build A Giant Bristlebot
A scuttling robot, scaled up
One of the simplest and most popular DIY robots is the bristlebot, a contraption made from a toothbrush head glued to a small vibrating motor, which can buzz over a flat surface. When DIYer Randy Sarafan, founder and manager of the Instructables Design Studio, was building a simple bot that would roll a tennis ball across the floor, he decided to power it by putting a bristlebot inside. But to provide enough strength, he would need to scale up the bot. In this Build It video, Popular Science demonstrates how you can build the giant bristlebot Sarafan designed.
