Hinges not moving out far enough when stacking

Hi all. Sorry to make another topic about the hinges, but this time, when I am stacking, the little flaps still grip the cube. The intakes arent moving out far enough when stacking. I have tried various things, like adding metal to the sides, adjusting angles, and pushing more to the side of the intake, however nothing has worked. Thank you for your time and I would appreciate your thoughts on this issue.



i have my intakes so it is a smaller sprocket in front and a larger one in the back. that should fix your problem right up


Hmm, it would fix it, but I have found this config would be better for intaking a lot well.

idk, mine intakes pretty good

You could just reverse the rollers as you back away

I would put spacers in between the hinge and the intake module so the intake module sits farther away form the rotation point. This should increase the distance it moves, but you may need to lower the entire intake system or where the intake sit to maintain your intake traction.


I currently have a 0.5inch standoff in there, and I believe it will only rotate to where the chain pieces are out of the way, and the flaps will still extend out and grip it

Btw, if I’m not mistaken, that robot isn’t competition legal because it has multiple sheets of plastic…

They could all be cut from 1 polycarbonate sheet

That’s 100% legal. They are non shattering polycarbonate made from the flags last year


@squiddy_slapper as per :

A limited amount of custom plastic is allowed. Robots may use non-shattering plastic from the following list; polycarbonate (Lexan), acetel monopolymer (Delrin), acetal copolymer (Acetron GP), POM (acetal), ABS, PEEK, PET, HDPE, LDPE, Nylon (all grades), Polypropylene, FEP; as cut from a single 12” x 24” sheet up to 0.070” thick .

Using one flag would be legal but not more than one—assuming that I understand the rules correctly.

Also, see this Q&A.

The single sheet of plastic rule at the end of means that you should be able to arrange all the lexan on your robot into a 12" x 24" sheet. Also, the Q&A you linked talked about the platforms being illegal, not the flags.


All that Q&A says is that flags from TP are legal, and the “as cut from a single 12” x 24" sheet up to 0.070" thick" clause simply means that all the peices used can be arranged in such a way that they would all be able to be cut from a single 12" x24" sheet. The key words in that clause are “as cut” meaning the pieces could have all been cut from the same sheet.
