How Can You Make A Closed Loop System????

[Chubtoad]

Depending on how many times you operate your Pneumatic elemnts and how much each of them take, you might not need the compressor. We happily eliminated the compressor from our bot this year. I was VERY against the idea initially, but in test we did not need it. Our two grabbers each run at 60psi but aren't used enough times to be a threat to the system. Engineering also entered into it because our grabbers only use the pneumatic to RELEASE. The only other pneumatic element is our ball dumper thing. We stock the balls in our basket then the piston retracts and the door opens letting out the balls. For safety we can actually close off the basket piston and there is enough air in the lines from the cut off to the valve that we could power the dumper twice, but it doesn't autoreset itself so we only are ABLE to dump once (mechanically). we are running off of the storage tanks @ 120psi. We can release a goal about 20 times, we have never gone off of the field with less then 40psi, usually above 60. Well actually at the LI Semi-finals a robot stuck their grabber into us and made a hole in the lines coming fromt he storage tanks, so we went off the field with 0psi Just saying that if you engineer it, you don't necesarily need the compressor.
