A couple questions:
1. That gearbox orientation looks really nice, would you mind posting a picture of the gearbox/internals of your drive?

2. What OD and ID tubing is that on your structure and why did you use that this year?

3. Any issues with balls jamming in the hopper/conveyor?

4. The entire robot looks incredibly light, what was your final weight and what was your method of conserving weight? How much pocketing went into your structure and what material thickness is used around the whole bot?

Looks incredible, thank you for such a beautiful machine. Best of luck in Sacramento.

1) Not sure where to find pictures of it (there probably are some lying around somewhere), but basically we have a 2-speed transmission using compact pistons from Bimba. It is a two-stage transmision, so it is relatively small, and we were able to orient the CIMs such that they are over the center wheel, out of the way of the electronics.

2) It is 1.5" OD 1/32" wall tubing. We are using it because it is rigid and light.

3) Seems to be working reasonably well. I haven't been at the more recent drivers practices, and I usually don't stay very late, so I can't say for sure.
