Roaming Robots Winter Tour
The Roaming Robots winter tour made a late but exuberant start in Portsmouth. As usual, there were three weekend events over October and November, and three cities with each well advertised event attracting a paying crowd for two or three shows.
You can control your robot with a simple relay H-bridge that gives you just three settings: off, full forward, and full reverse. These controls — sometimes called “bang bang” for the way they drive your machine — are cheap and easy to make.
Power packs can be expensive, but if you build your robot from cordless drills you have two battery packs complete with chargers left over. Use them to power your bot.
