No one wants to be the team that damages another team's bot, and that one could have ended badly. 3200 were great sports, BTW, kudos to them.

Did you actually make contact with their robot? I didn't look that closely in at the video. If you didn't contact the robot in the frame perimeter, is it a foul?

We did indeed. Here is a new video, just finished editing, with the same scrimmage from a different camera and from more of a journalistic perspective. It also includes footage of the team's response to the accident in autonomous that caused the arms to break. It's nice because it shows some of the mechanisms up close, and also because it lead to several improvements being added before Bag & Tag.

We've been very fortunate to have several students willing to take on videography this year.

We actually have a similar design and were wondering what you are using to power the wheels from the Cims. Is it V-belt, timing belt, chain? We tried using V-belt but are having a lot of problems with the Cim not being able to get past the friction in the V-belt and pulley. Do you have any suggestions?

Also what type of metal are your shooter arms made of? Is that just box aluminum?

Thanks so much! And Good Luck!

We used 9mm HTD timing belt to power the wheels. As for the materiel it is just plain aluminum tubing.
Expect a follow up on suggestions.

Glad a couple teams went through with this idea. I had toyed with the idea, but our initial proof of concepts with wheeled shooters had very poor results, and we didn't have the time or manpower to go further down that path. Part of me still wishes we did.

What speeds are you running your shooting wheels? How much compression?

Thanks for the vote of confidence. We went this direction because, for us, our previous experience made it the most comfortable fit. It was really a lot easier for us than the other options we saw and/or prototyped.

We are running miniCIMs with a 4:3 reduction, so 4650 free speed. Compression is 4.75" on the nominal ball size.
