Intake systems

Ideally, the collector opening should be large, so the driver has a nice big, easy target. Also, when designing the intake there should be some consideration for the range of angles the driver can take to pick up a ball. For example, a 973/177/1477/2415 intake (118 had one too that I got to see, but they had to scrap it for weight) has a large angle that balls can be picked up from, since it can intake from the sides. This way the driver doesn't have to drive head on to pick up a ball, just basically touch it with a roller on any side.

While area is important, it counts in some places more than others. Many teams recognized that it is important to have as much area available as possible for picking up balls, but for some reason didn't think up an over the bumper intake. Some of those teams (like mine) chose a two sided through-the bumper intake (see 256).

What we all found is that when it came time to play at regionals, some area is worth more than others. Big movements, like turning the robot 180 degrees to pick up a ball, are far less difficult than the fine positioning needed to get a ball into a through-the-bumper intake. Although teams like 256 had more perimeter dedicated to picking up compared to, say, 254, but not as much contiguous area. That's what count's for drivers.

I will say the best I saw was the over-the-bumper, full robot-width, using poly cord and rollers to funnel into a hopper style. It was simple, fast and efficient. There's another thread on best-of for Rebound Rumble here.

Here is one of us 2826 at Championships

987's intake system (starting around 1:20)...

There's one of 2056, with an intake similar to 2826 (which is why I grouped them together. Also, 67's arm can be seen in the video Ike posted featuring 469.
