0 Redesigned rotary movement for shoulder

I've moved the motor that rotates the robot's arm inside of the chest cavity to save space. The previous arm configuration was based off of one of my first tests for mounting the robot's arms which used a motor mounted in the arm. Mounting the motor inside of the robot's chest cavity will allow me to reduce the weight of the robot's arms for future versions.

I'm currently modeling a new left arm for the robot which will incorporate more joints for an improved range of motion.
