Eliminating Arm Wobble
This year team 1768 uses an arm driven off of an Andy Mark work-gearbox. The issue we are running into is that when the motor is stopped the arm has quite a bit of wobble back and forth, some due to imperfect gear meshing, some due to imperfect coupling of the arm to the shaft. We have added dampening to the arm in the form of a gas spring, however we still see a decent around of this wobble.
How do other teams deal with this for smooth operations of larger arms? Watching some of these other robots operate their arms so smoothly has me thinking there must be a handful of tricks that all need to be completed.
