1)Setup bot as per XLR8 tutorial without interfacing with a Bluetooth Module, i.e. setup chassis, wheels, motors, a power source, motor driver circuit uing L239D, etc. Two wheels with a ball caster should suffice. XLR8 Tutorial
2)Connect motor controllers to the Arduino (digital output pins).
3)Setup three IR sensors and attach them sufficiently close to the motors.
4)Reconfigure code to reflect actual pins and differerntiate between line and background.
5)Burn the code on the Arduino
