Build It - Giant Bristlebot

One of the simplest and most popular DIY robots is the bristlebot, a contraption made from a toothbrush head glued to a small 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 with a bristlebot. But to provide enough strength, he would have to scale up the bot. In this Build It video, Popular Science demonstrates how you can build the giant bristlebot Sarafan designed.
