I’m not sure what you are referring to by cross talk, but we choose to use coarse gears for our drive to account for any servo misalignment. As far as the servos fighting each other, it is very minimal and only towards the limits of their travel.

Very cool, I would be interested in seeing how to work the math for this. (Im a programmer by training so most problems involving the real world are beyond my skills in physics)

By cross talk I am referring to the nasty problem of when the wires from your servo (or sensor) act as an antenna and pick up the magnetic field from the wires on your motors. I recall 2006 when we would turn on the shooter wheels and our camera servos would go crazy.

06 also had the issue of many shooters being Van de Graaf generators. Large static charges make servos a little unhappy.

Very nice! I marveled at your demo-display in Atlanta. I do believe this is deserving of a white paper. Any chance one is forthcoming?

Ironically I saw you guys at 4 competitions and was even in your pit and never noticed this. I saw the display but never had time to actually look, I meant to at MSC but I never got around to it...I'm impressed and by the awards you received for it so were the judges...nice work.
