Best Intake

I'm just happy our robot was that memorable!

Using catapults, I'm going for 610's intake. At first I was skeptical of the need for an intake like theirs, but I've since seen plenty of robots stuff themselves using their own intake because it has to move out of the way, outside the frame perimeter, ready to be hit back inside the frame perimeter by a defending robot.

For linear punches, I'm going for 971. It can intake a ball in multiple scenarios, including a bouncing ball.

Check out 1718 top roller design, it is done really well. The top roller is spring loaded, and has about 4" of travel, to keep contact with the ball while controlling pressure on the roll, and the sides of the arm is made of some material that flexes and springs back into position.

It was a thing of ugly beauty.

We have 1x2 thick wall aluminum tube that has not broken, but we have cracked welds after each weekend.

1718 has the bend but don't break design, that just works better. Nice job Pi.

I thought Spectrum's (3847) El Toro was pretty effective, as well as 148's.

233's punch was very impressive, it didn't have anything to center it besides a Frisbee, and even when it was off center, it still shot accurately and consistently.

But there have been great bar roller intakes too, the ones that pop into my head are 33's and 254's. 1538 refined this even more to keep pressure and account for variable compressions of the competition balls with the sliding rollers.

Also, not sure what category they go into, but 610's articulated rollers are pretty cool.

I don't see the advantage of a non-roller or pinch setup over a well-built roller system, seems like added complexity for no real benefit.

We are pretty proud of ours. Its fast and it remains in contact with the ball for fast low goal dumps.

We made use of bevel gears so that we could have both top rollers and side rollers. This allowed us to glide over the ball from more than just one direction for pickup and was one of the reasons we were able to go 18-0-0 at the Hawaii Regional this past weekend. It also made it so that our second ball for our two ball auto could be put to the side to more easily touch our alliance partner's bot.

Haven't been able to upload Saturday matches, but here are our Friday ones.

Wow. Thanks for the props. Being complimented by the #1 Waterford seed with an incredible Autonomous is good for the ego!

The vertical arms are made from 1/4" expanded PVC for stiffness, with 1/8" lexan laminated to the outside. The foamed PVC give stiffness, and if(when) it cracks, the lexan allows us to keep playing. Team 16 the bomb squad's 2008 pickup inspired ours.
