The nice thing about using a potentiometer for position sensing is that you don't have to home the thing. There are lots of alternative sensors, but most are bigger, heavier, or more expensive. If 1% precision is good enough, pots are fine. The next step up is Dynamixel servos, which have a nice daisy-chain digital interface, encoders, about the same form factor as toy-type servos, at about 10x the price.[1] | ||
