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.

When the students that made the video premiered it in class, those of us that had been at the scrimmage laughed out loud. That was a very tense moment for us, as our driver was just testing the physical limits of the bot and didn't mean to contact the other robot. We weren't alliance partners, as everyone there just used whatever bumpers were convenient. We apologized to the other team and learned a few valuable lessons. It was funny that the videographers chose to show that particular error to the world.

The belts pass through the arms, which are 1/16" tubing. We chose the thin material for its weight on the moment arm, but it's been a lucky choice in that it will break without damaging any other arm or robot parts (learned by experience). We can bring extra arms and change them out with a pretty quick turnaround time.

Just want to make sure it's super clear that nobody on our team thought the foul was cool; we laughed at the video because we remembered how embarrassing it was when we drove into the other bot. I thought the kids handled it well afterward, but like I said, it was tense. 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.

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.
