This is a heads-up that we have added some new methods to control the GoPiGo3 motors in easygopigo3.py:
spin_left()spin_right()orbit()steer()
You were always able to have this level of control from the gopigo3.py library. We just wrote wrappers to make them more accessible. The orbit() one is my favorite. Assign a radius and an arc degree and watch your gopigo turn around an obstacle ! 
spin_left/right makes the robot turn on the spot instead of around a wheel. And steer lets you control both motors at the same time.
