Convert an RC car to Arduino Robot Platform
This main guts of the project are based on an Arduino Uno and a Arduino motor shield. Randofo removes the stock innards and wires the motors to the motor shield. This particular truck has a single rear drive motor and one steering motor. I would think that just about any cheap RC car would work. The explanation is pretty light, but I think the ultrasonic transducers are for object avoidance.
The project is well documented with step-by-step pictures. I especially like the build quality. The whole unit looks like it would be pretty solid. The entire unit is powered by an off the shelf 9V battery. The only upgrade I would suggest would be a better battery pack. I would imagine that those motors would drain that 9V battery in no time. A rechargeable would be great, maybe the Lithium Polymer shield? And I bet you could charge it with the 5V USB connection.
This project would be a great starting point to learn motor control and ultrasonic transducers! Arduino code is provided.
