This comprehensive tutorial covers the insides and outs of basic robotic design and construction. In fact, you can have a complete robot within about two hours. If you’ve always wanted to build robots, but didn’t know where to start, this is for you.
This is a walkthrough on how to make an autonomous, self-exploring, “own-mind” (not remote-controlled, not strictly pre-programmed, but reacting to surroundings) robot in a few hours. It is really easy, and it does not involve knowledge of electronics to get you started with robot-building.
