How much torque do I need to drive the rotation sensor?
This was my first plan of action, but I was limited because I don't have a
rotation sensor other than the NXT motors themselves! From a purist point of
view, I would really like a mechanical solution; once I go to sending feedback
via the wires, all the really cool mechanics I've worked on are for naught!
Do you think I could just use the nxt motors somehow or is that too much torque?
We are talking about an amount of torque less than (purely hypothetically, of
course) a Lego soccer ball falling 3 studs from the center of an axel. I guess
that would be 3 stud-balls of torque!
