Greg and I had our first discussion regarding the bot. Unfortunately we are both busy with University but have come up with a means to complete the machine by 29 April 2014 (we both really want Hackaday shirts and have been threatening to make another bot :-P).

1. A Cybot body (the old Real Robots bot) will be used as the initial chassis, along with it's avoidance sensors and motors.

2. An UNO32 will be used to operate the droid

3. A simple transistor based PWM motor controller will be made for efficient movement

4. A homing beacon will be made (possibly with R2D2like tones) to guide the droid once a coin has been found

5. A difference amplifier will be used with a variable strength electromagnet to both detect and collect coins without wasting battery power
