Re: pic: Team RUSH 27 Hanging at Kettering

Theirs takes about as long as ours, which is around 6 seconds max to get all the way up (less to get above the platform). They seem to pick their robot up higher (to put more mass forward of the arm sprocket to prevent backdriving back down?) then us. As for the complete time to unfold and hang, ours is probably larger because we must position the robot close before moving the arm, since the arm drives the center wheel articulation in our chassis and without that wheel down we can't turn. At the 20s call, we run over, line up, deploy the arm, and flip, with around 4s to spare. Look for an improvement on that time in the future. As for 27's arm, they have a 6wd drop center chassis that does not articulate like ours does, so they can deploy earlier.

Speaking of 33 vs 27, how do you guys on 27 power your arm? We have a CIM with around 800:1 through a DeWalt, Toughbox, and chain reduction. You guys seemed to have a lot more bungee than us (we have none), do you have a f-p for your arm or something? I didn't get a chance to look at it.
