I spoke with a Barobo representative at San Mateo Maker fair and I though he mentioned that your link bot offers high precision absolute motion encoding for its rotating face-plates. But when I look at your kick starter, you’re offering modules for < $150. I’ve given up some robotics projects in the past because of how expensive positional encoding sensors are. How have you managed to get two absolutely encoded rotating face-plates + micro controller with wireless and accelerometer in such a small package? An encoded motor attached to an arduino compatible board at this price opens up a lot of options for a spare-time hobbyist like me.
