It can be easily be remote controlled.
If you do want to make it one you can eliminate all the electronics like capacitors or the PC boards unless you want to use them in the future.
The only things you need for an RC $50 dollar robot is the material for the base, two servos, your batteries, the wheels, and a receiver and transmitter with the same frequency crystal.
You won't even need to program it.http://www.societyofrobots.com/remote_control_robot.shtml
Sorry, I don't know much about bluetooth except for the fact that it's using wireless to control something or something like that.
If you want to make it simple, you can do RC but it might not be too much of a challenge for you.
