Convert an RC car to Arduino Robot Platform

Randofo over at Instructables posted quite a writeup on converting a RadioShack RC car to Arduino robot.  In fact, it looks like you can acquire all the parts at your local RadioShack.

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.

Check it out!
