Re: compressor & Possession questions
We use two Fisher Price (FP) motors for our ball magnet running through BaneBots P60 transmissions but that's because we have rollers running in different directions and it was easier than using gears. Many teams have a single powered roller so a single FP would be fine.
FPs don't enjoy being stalled so if your ball magnet has a habit of doing that you'd want to dial back their speed in software or use the Jaguar's current limiting mode so as to avoid them drawing more than some preset limit. We limit ours to 10-15 amps in stall for the ball magnet. Rumor has it the new FPs have internal thermal protection and will shut themselves down before smoking but it's not something we rely on. Besides you don't want your ball magnet shutting down unpredictably in the middle of a match!
In terms of charging your air tanks, look at R75-R79 in the rules. Essentially you are allowed to have your compressor off-board but the power to drive it must come from your robot just as through it were on your robot. We charge ours from a push-on fitting in the Parker vent valve.
