Over at Let's Make Robots, I found this great robot that looks really similar to my first robot.
Designed to be operated by remote control, Mega Rider uses two continuous rotation servos to drive wheels made out of CDs. It also uses a ball caster for the rear wheel.
I love these kind of projects because this is how you get started. You don't get started in robotics by buying a $10,000 robot and expecting it to bring you coffee in the morning. Start with $50 in parts and you can have a basic robot you make yourself. After you build some robots, then you can worry about buying expensive sensors that you just want to disassemble.
The robot looks like a great starting point for bigger and better projects.
