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.
