This remote-controlled car can be moved around using practically any kind of remote such as TV, AC etc.
It makes use of the fact that the remote emits IR(infrared).
This property is made use of by using an IR receiver, which is a very cheap sensor.
 
In this instructable, you will learn how to
Interface IR receiver to Arduino.
Interface 2 motors to Arduino.
Combine the above 2 setups.
