moMo : Version 4

momo version 4 now has a sturdier lighter frame. A couple switches were added to control power to arduino and to the GPS unit. The whole unit somehow runs off 4 AA batteries instead of 8. I also realized the compass unit is not as accurate as we’d like. It has a sour spot around 180-270 degrees where the measurements are noticably off by several degrees, not due to electromagnetic interference from the nearby motors.
