You should consider maybe 40a or 60a 4 inch flex wheels on the flywheel.
On the back you basically have c-channel stacked on more c-channel. You could try replacing it with standoffs to save some weight.
How heavy is it?
What are the rpm’s and sizes for the rollers?
We really want to test the flex wheels hopefully we can use them soon. The c-channel is kinda a purpose-built wall to ram into things, and it holds the balls in place so we don’t over use the Lexan. To answer your questions it is surprisingly light. I would say 10 pounds but I don’t have an exact number. The rollers are 24 tooth sprockets, with the motor being geared turbo. The back roller is weaved and on a high strength shaft. If there’s any other questions I would be pleased to answer them.

I think it was a last second add on and it hasn’t had its perment mounting position. I believe that’s why the wires are hanging across the robot not completely tied down. Just in case it needs to move to a different place. @Golf
Yes we can, it’s usally stopped to not put unnecessary wear on the motor. In fact I think it speeds up right before the ball hits the fly wheel but that’s something to ask our amazing coder (@trontech569)
I think flex wheels or rubber band rollers are a lot more efficient at launching balls at a very short distance than an actual flywheel, might want to experiment with those. otherwise looks pretty good.
My poor building skills lol. It was a recent add-on. The screw and locknut that were holding on the vision sensor got a bit loose and I hadn’t had time to fix it.
Well we could. At the moment we aren’t because I had programmed the flywheel to spin up to shooting speed when one of the two optical sensors was triggered. Since one of them was taken off, the code runs at full speed by default. Flywheel speed is definitely high up on the list of things to work on.
I think that you are correct, but at the moment there are a couple factors contributing to this for us.
We don’t have flex wheels. Not a major issue, but still a small one.
Our robot was built from the X-Drive and up to the flywheel. I don’t think we could just swap out the flywheel for rubber band rollers, due to the distance the flywheel is from the top of the goal. It would probably require some rebuilding.
Our team has not yet competed in any tournaments. Without much sense of how good our robot is right now*, it seems a bit hasty to start rebuilding.
Having watched some of the in-person videos, I suspect that our robot would fall behind, but we are in California, with very little chance of competing in-person. However, watching the live remote tournaments, several teams are finishing before the match time limit is up, which implies to me that we could perform well in a live remote tournament. These are just speculations though.
good point. one aspect of live remote tournaments is that as long as you can max out the field in 2 minutes, there’s no point in doing it better. imo that’s the biggest flaw, but it also means you only need a somewhat decent robot, not a really good one.
