Great looking robot (especially next to our wooden collector)! Didn't have much time to see you guys play; too busy figuring our stuff out. One thing I noticed was that your robot has what appears to be six air tanks on your robot. You guys planning on crossing the dridge that often?

Actually, because the elevator is on the same motor as the intake, we needed a way to run the intake without moving balls towards the shooter. To solve this problem, there is a lexan "backboard" that is attached to a piston. The piston changes the compression against the ball enough such that, when the "backboard" is in the back position, we can run the elevator and the balls just spin in place. Once we engage the backboard, the balls have enough compression to move towards the shooter. Thus, in short, we require movement of a piston each time we wish to shoot a load of balls as well.

We did find, through experimentation at the field, that we had enough air to last us approximately 7 minutes of full game simulation. One of the upgrades we plan to make for BAE is to remove the cluster of tanks and replace them with a few plastic ones.

Jack and 2791 stepped up an insane amount this year.

And part of the lack of wood and PVC is due to the EWCP harassing Jack about 2011

Very nice robot 2791! Jack, what is the range difference when the shooter hood is retracted and fully extended?

That's really cool! I assume the usage is too much to have a compressor that keeps up, or the weight of a compressor gives enough tanks to hold the air for one match. Can't wait to see you guys at BAE (and CT for that matter).

We're actually losing hood capability for BAE and CT. The hood was designed to make two pointers from the fender easier in case we weren't accurate enough at three pointers from the key. However, at the field we determined we are fairly accurate at threes, and the hood position had very little effect on how easy it is to make twos. By losing the hood, we can save almost 8 lbs for weight we can put down low. We like to tip a lot. :/

We don't have enough weight for the compressor and sufficient air storage. Also, We don't have the budget to purchase the new small compressor.

Re: pic: Team 2791 Complete

I'm assuming your electronics are all stuffed around the conveyor underneath the Lexan. Widebots like that love to tip; we found it's best to move electronics as close as possible to try to at least get to a... teeter...
