We haven't tested catching very much (due to the aggressive nature of Arial Assist the line-up is difficult) but we are definitely capable.
Have you seen the way 2056 catches? They line up against the field wall and all they have to do is backup or move forward to the correct distance.

Thanks, that looks like a good strategy.

Re: Code Orange 3476 2014 "Hanalei" Robot Reveal

That's a very nice design. Kauai is one of my favorite places to visit.

What is the purpose of the two 1" square tube arms that come up at 0:37, 0:38 and 1:13? Do they modify the ball trajectory or do they keep the ball in the proper location for the shooter arm? What is the purpose of the polycarbonate "hinges" in the middle of those arms?

What is the ball on at 0:14?

Thanks.

Thanks.
Thanks. The 1x1 extrusion arms are for both positioning the ball and choosing a trajectory. As for the hinges, they allow the ball to quickly roll over into the catapult while also allowing us to hold the ball securely in place for driving.

The thing at 0:14 is a LEGO robot built to carry the ball. It was just a joke.

Has any other Robot Shot in Autonomous for the High Goal, Missed, then Caught the Re-bounded Ball and Shot it to Score in the Hot High Goal? Here is a 6 second video from the San Diego Regional, Match #11, showing "Hanalei" doing just that: http://www.youtube.com/watch?v=ufF0g_Tj0ts
We are getting ready for the Las Vegas Regional, April 3 - 5, 2014.

Is this programmed to do this? just in case you get bounce back? If so that's pretty unique of your programmers to think that far ahead.

Answer42-
Hanalei is programmed to run an auto mode that just shoots the first ball in the goal and then drives forward with our intake on. We have limit switches in our catapult that detect whether a ball is in the catapult and we use these to wait to shoot until our next ball is in our catapult. This runs on a loop for the rest of auto so if any balls get near our intake or bounce back into our robot we can shoot them. This also prevents us from dry-firing our catapult too often or mis-firing if something else in the autonomous mode has delayed the ball from reaching the catapult in the normal amount of time.
