Thanks! We had hella fun designing and building the guy. At first we felt like we did something horribly stupid and joked around with our friends on 330 at CVR this year!

Thanks Sisk for posting the pic, vids of it are here:

Thats quite incorrect.
As the 4 bar linkage is very very simple to do... It all depends when you saw us as well. At Davis we had major code problems and had a very rough start, as we had a new programmer that didn't fully grasp what we were doing. We've never been amazing at code, and this year we built the 4 bar so if for some reason we didn't have the code we desired. We could pick up balls, lift and score a very high percentage shot (ball variation killed a lot of key shots).
According to the scouting data that was linked in Akash's post, it shows that we were the highest point conversion robot in our division (~89-90%). Shot a ton of balls and missed very little. Unless stats lie
Everyone for some reason feels that we have a very very very absurdly high CG... At Davis when we had code issues, our arm was stuck midway and we traversed the bump without flipping. We've scored points and the other robot has tipped trying to push us. We did a lot of math and knew what situations we'd be in. We've had a team or two come up to us at champs before a match and tell us we have a way high CG, but then they tip going over the bridge. Its not like we drove around with our arm up like crazy people

And it wasn't honestly a ton of mechanical complexity. It added about 4lbs of extra weight and the system was pretty darn light/simple. Many people came by and checked out our setup. Most were quite surprised how simple/light the pieces were.
If we had to do it again, we would still do our 4 bar lift guy. As it allowed us to score accurately, added very little weight and made us pretty versatile. Many people thought we couldn't key shoot.

But we could probably key shoot as fast as we could fender.
