Re: pic: Butterfly Drive Concept

Naming it an actuatable slide drive would probably be more accurate, I hadn't thought of that. I called it a butterfly due to the shifting of the wheel modules.
I know 50lbs is a lot for a drive base and I've been working on lightening it. The upper supports are there for bumper mounting purposes but I will probably work on revising it by maybe removing the front and back rails.
Yes 7 cim is overkill if I were to actually build it I would almost certainly just use 2 cims in each gear box and a minicim for the center (depending on game)
As for cylinders I'm trying to design to take advantage of some 3/4 inch throw that were bought for last season but never used. So the cylinders in the CAD are just place holders. I can edit the design to change where the cylinders are placed.

The extra wheel in the center is to make it function so that the wheels would dig into the ground when they are powered. This is so the wheels still have contact on slightly uneven surfaces.
I checked through the weights in inventor and I'm fairly sure there all assigned right.
The tubing is versa frame which is already .1 inch wall.
The plates might be pocket a little much I will probably change that for the next revision.
