But here’s the thing in order for that roller to work you have to stop the front rollers which wouldn’t really matter in tournaments and state but come worlds you’re going to want something that is faster and more efficient

What size sprockets did you use for the rollers? I can see that the bottom one is 18t and the top two are 30t, but I cant tell for the two middle ones
@xenon272723 жыл бұрын
bottom one is actually 24t. middle front is 30, launcher is 30, top pooper is 30, and bottom pooper is 24. I like to stick to the larger ones for more compression and faster surface velocity.

I have a question, how did you make it so that the intakes could intake without balls rolling on top of it, whenever I try to cycle quick, the balls just end up getting stuck on top of my intake (because sometimes the ball would just start rolling and wouldn't come down so that the intakes can bring them into the robot
@xenon272723 жыл бұрын
it's a matter of finding the perfect spacing/tension on the intakes so that the balls don't have trouble falling down through them.

there are rubber band pulling the intakes outwards. they're held in only with friction against the wheels of the robot, and when they first spin that will dislodge them.

Do you have specs for the robot? And how do you keep the arms back before the start? Are u using rubber bands?
@xenon272723 жыл бұрын
specs are at the end of the video. as for the intakes, friction just holds them in until they first spin, which kind of dislodges them and lets the rubber bands pop them out.

How does your drive not overheat and drain the battery I have mine on 257rpm and I have those issues
@xenon272724 жыл бұрын
well the battery isn't going to be drained more than normal by the drive no matter how fast it is, sounds like a battery problem. as far as overheating, you just need to build everything solid and with low friction.

I really like the design, I am just curious as to what holds the intake arms back at the start
@xenon272723 жыл бұрын
there happens to be just enough friction between the flaps on the rollers and the top of the drive wheels that I can bend the intakes back and they will hold in place, until I spin them then they pop loose. this probably won't work on other robots though.

Do you think having the sorter can mess up your skills run by descoring a blue and bumping into a red which would then mess up your routine?

perhaps but that could happen just as easily without a sorter, because you have to discard your blue balls anyways.

Hey, I have a question. Correct me if I am correct, the "flywheel" and the roller directly behind it are completely powered by 1 motor. If so do you think that is powerful enough to last a few minutes, so basically I am asking if it overheats and gets stressed quickly. Great robot by the way

it could go indefinitely without overheating, it isn't going fast enough to get stressed out, so one motor is plenty.

@@xenon27272 With a lexan back since it is hard plastic it would be faster. But it may be more complicated. Also, the ratchet will allow it to power the flywheel when its not powering the flap on the back. Your design is simpler but I'm not sure if the cycle time would be faster. Also, Does your design have ratchets, because if one motor is powering 1 side and one powering the other it may overheat.
