MIT 2.007 Robot

This year the robotics competition was county fair themed. Robots scored points for dispensing tickets from a booth, ringing a bell on a high striker, inflating a balloon, and spinning a Ferris wheel. This robot uses springs (not in model) to fling the weight up to the bell using the basket on the front. It then backs up against the rims of the Ferris Wheel to spin it with friction (there is a timing belt transmission not included). It runs on a 7.4V 500mA/Hr Lithium-Polymer Battery and is controlled using a wireless PS2 controller mapped through and Arduino Nano Microcontroller.
