I would suggest not adding rubber bands to the intake flaps because it might make the flaps positioned in inconsistent positions and like you said, this seems like a pretty jank solution. It makes more sense to put rubber bands around the sprocket closer to the inside of the robot if your rollers are not chained together or if you have arms make the arm bracing stronger so the arms don’t twist when intaking. If your robot uses Flipout rollers you could improve the hinges for the flip outs. I would also suggest using the forum search bar as there is already a lot of threads on cube compression.
I figured out a simple and easy lock mechanism for intakes to fix nearly all compression issues. The tricky balancing game between strength, being able to bend the intakes back, the bands not snapping, and the arm spreading when the tilter is tilted forwards is solved by a simple lock as seen below or on youtube

Our team has a tray bot that can go as low as 30 degrees, and we are working on a tray that expands for room for 14 cubes. I wanted to do some research to see what intake could possibly do that right. Assuming torque is not a problem (can just use 100rpm motors with 12 or 18 tooth sprockets) what are some good tips to help with compression? Is there a way to make the flaps grippier or have a certain flap pattern that fixes compression? How far apart should the chain itself be from the chain …
Alright, so I’m sorry to post another topic about compression issues on intakes, but I searched for a while to an answer for this issue with these specific hinged intakes but I couldn’t find one. Can someone advise me on how to fix the compression on [IMG_0477] [IMG_0478] [IMG_0479] [IMG_0480] these intakes?
Hey, our intake doesn’t seem to have enough compression to do above 10 cubes, but it jams and motors get stuck like there is too much compression. It isn’t the cubes getting stuck on a surface in the tray, rather just stuck in the intake itself.
Our intake is:
-Rubber tank tread + small flaps, double chained
-Hinged
-200rpm 18 tooth sprocket
-Has wings + mild tensioners for low friction
-4 fresh double rubber bands for compression
-Compression towers + HS axle on arm
We are hoping for an…
Would you guys suggest using a high torque gear box for our two intake motors? Our robot can reliably intake about six cubes but then we start running into compression issues
I have a double reverse four bar lift attached to a tray and intake. The two intakes roller start to bend out after intaking 5 cubes. I already added 5 rubber bands per side. The intakes are attached to the top bar of both sides of the lift and the two bars tend bend as well.
