Best Intake

That pickup is slick, I also like the effective over the top pickups that have been made. Similar to the VexPro Build Blitz teams. The 1114, 179, 118, 233 pickups that are all similar to the 971 pickup in some way are all very effective. I honestly, after this weekend have learned to strongly dislike the toro intakes. However, when done well. The toro intake is still effective.

My main favorite for now is the over the top intake.

The over the top roller intake works so well because it doesn't rely on the robot being in exactly the right place, and it also "grabs" the ball instead of letting it bounce off the robot. The key is that it pushes the ball against the floor, so it can grip immediately.

The 842 grabber relies on some serious control system magic to make it so effective.

Some intakes naturally work well, and that's the one that you want to make if you don't have the ability to perfect a less optimal design.

Those are either photocells or ultrasonic distance, or vex touch sensors they have on the grabbers to detect the ball's presence automatically. Simple magic maybe. Effective nonetheless.

Really? I thought it was an IR imaging system, with onboard processing.

I wonder why it would be an imaging system. I mean. If I understand the concept of the intake well enough all you need to do to make the intake truely effective is to be able to detect the ball once it reaches the optimum distance range between the grabbers/distance from the bumper so that it automatically grabs the ball.

I've been developing an intake that functions almost exactly like theirs does and it's working almost exactly like theirs with only a Maxbotics sonar sensor to detect the distance.

We have a similar intake and I believe we are using an infrared sensor to close our paddles around the ball. (I could be totally wrong, I'm not an electronics guy).

It is an IR sensor.

Gotta love how a judge knows more about my robot than me. CAD team problems

I'm more impressed I didn't have to consult my notes.

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.
