paper: Killer Bees 2011 Robot CAD model

[Jim Zondag]

I'll elaborate a little more:

We designed a custom 3 motor transmission in the first week. We made all the parts but did not have the Banebots transmission required for the 3rd motor when we wanted to assemble everything for the first drive tests.
So we built it up without these. In week 3, when we finally got some details on what a CIMulator actually was (no drawings or anything on BaneBots site), I did a little work to see if I could also fit 2 of these into the assembly instead of the P60 transmission, since this solution is slightly lighter.

We ended up very close on weight in week 6, and the robot with 4 motors was capable of meeting all of the performance objectives, (it is really not geared super high) so we decided not to put in the 3rd set of motors. Later when we got a little weight back, I did not make this a priority, since the robot can hang 9 tubes the way it is andthis game is mostly about auton and minibots. We spent most of our additional developement time on these areas.

Both of these motors options are suppressed in my Inventor Model, but it appears they get re-enabled during the STP file conversion process. This is why you see them both in the model. Our crate arrived from STL this afternoon. When we get a little time, we will probably put 2 of these in, but I haven't decided which design yet.
