i've tried so hard to prototype this... You're awesome

That is ridiculously fast! Great work!

How did you do it?

We were next door to these guys when they were working on this. It was awesome to see them work. The motors were just BAG motors connected to versa planetary gearboxes that were 1:1. It moved wicked fast, about 200ms or so if I remember the talk with their mentor correctly. Such an awesome team.

See the engineering journal with our design/ build process here.

Edit: Steven beat me to it. I'm happy to answer any questions not covered in the engineering journal.

I had the good fortune to work the right side of Curie when 842 came out for a match. I put my iPhone into slow-mo mode and got some magic:

Awesome work!

THAT is amazing to watch lol out of no where they grab the cans, did you all hook them up to a motor?

They are driven by a 1.625" BaneBots wheel powered by a BAG motor.

Wonderful! And that's with just BAG motors; think of what you could do with a RS-775!
Your testing setup for them in the pits is very clever.

A 775 would actually be slower; it has a lower free speed.

We were looking into speeding the mechanism up by powering it with two BAG motors per side, but didn't have time.

Are the BAG motors running at free speed?
EDIT: You could always gear it up too, but that would probably use more weight then you have.
