In summary, I think that it is easier to go with a dc, get the h-bridge out of some L293, an encoder and voila!


If the system accidently shuts down, how will an encoder know the current position? You could put small pots at the arm joints to read the current position.
Consider the daffodil. And while you're doing that, I'll be over here, looking through your stuff.   8)

An encoder will still need some inializing/homing code, which you will need to do with the stepper motor anyway. Make sure the stepper motor/gearbox has enough torque for the rest of your mechanism and don't bother with the encoder.

Well, then stepper motors, but with pots for that accidental shut down, right?
