The first part of this series was an introduction to the core hardware for the SmartCar platform. This article covers the power supply, controller and sensors.
Many years ago I purchased a Rug Warrior kit to go with the book Mobile Robots: Inspiration to Implementation. It was an expensive kit – in the hundreds of dollars in Australia – for what was an advanced entry level robot of the early 1990’s.
The technology to make such a bot vehicle has become considerably more accessible, so I thought it was time to build a roving bot from the ground up. The challenge for this version is to make it as cheaply as possible for functionality similar to Rug Warrior.
