In the controls the scoring conveyor system can be stopped however the programming was glitchy and would for some reason control that too. Otherwise, its basically you store after intaking the balls.

Sorry for answering your questions guys :p

If you look closely at the pictures, you can see that there is a 6" long piece of kit frame rail at each side of the front, so they can indeed put the required bumpers on it.

Neat design, great progress, thanks for posting!

The upside to that is, though, that we know exactly what our robot will look like and what parts we need to make/order in order to finish it. Maybe it would have been a good idea to start building sooner - we have almost no time to test our finished robot.
We are the same, this is our slowest year however, it takes about 2 weeks every year for a final design. THen we build and we build slowly and carefully.

Us too we have a monster frame and everything else should go on in about a few days. Congrats Dustin on the sweet Bot, hope to see u guys at nationals.

We can store balls inside of our conveyor belt system by reversing the top most roller. We're having an issue with our program right now so it wasn't working in the videos

Great work though, are you planning on being able to stop your collection system and wait to release the balls or will it be constant?
Thanks! And We can fit 2 six in bumpers on the front.

For the conveyor, is that a form of chain? Like plastic chain?

It's adjustable length V belting. It's made of a whole bunch of little plastic/rubber links that twist together.

I don't typically like to give advice on robot design. I assume people know what's best for their own robots. But I think you need to rethink your top roller system. From the videos, it looked like the balls just fell out when they got to the top. Even when you didn't want them to.

If you move the top conveyor roller over and add a second output roller right next to it, you can make the conveyor and output two separate systems and eliminate the balls falling out. The balls would pile up at the top and be ready for dumping when you actually wanted to. Should be an easy fix looking at the design you already have and you still have plenty of time.

Alrighty dude, when we were talking on with team 816 a few weeks ago and asked what they were doing (EWCP). They said a shooter/dumper combo. So their plan is to have mass storage and bring it up like a shooter. But instead of shooting, they are making it a dumper. So hope that clears the confusion.

The top roller acts as a stop most of the time. We're having a programming issue at the moment so it won't reverse. When working correctly the balls stage in our conveyor system.

Most of the programming has been sorted out and we've made some minor mechanical tweaks. For those of you worried about us storing, here's a pic. We store 7 deep and 3 wide.

Hit up McMaster-Carr (www.mcmaster.com) page # 1030.
Alternately search "belting" and it should come up.
