Replace wired control with bluetooth

We used a bluetooth module to communicate over serial wirelessly. This allowed us to send our control commands without needing to be tethered to the robot.

Incorporate Battery Power

To help with the process of de-teathering our robot, we used a lipo battery on our robot. Because the voltage of the lipo was too high, we used a power converter to step down the voltage to 7 volts for powering the servos.
