Make sure there are places at the top edge to mount superstructure (i.e., manipulator), perhaps turn the top edge of the inner rails inward. Maybe make them a little taller too, so the top is just above the tops of the wheels - your manipulator team will love you for giving them a perfectly flat surface the size of the whole robot (your maintenance work will be from the bottom looking up). Also, count on using your bumpers as structural elements, which means only the mounting points on the outer rails need to be strong, the rest can be weak because you have that 3/4" plywood holding it all together. For the bottom plate, consider fewer and smaller lightening holes, as mentioned above so you can easily mount your electronics and gear there. Last, line up the shift pistons and use just one to shift both at the same time. There's a thread here somewhere that shows how one team did that.

Are the standoff bolts in the path of the chains ? maybe just one bolt
in the center will be ok, Or you could put a slot in this area to mount chain
tensioners, A shaft with tapped holes in the ends and a small roller
on it may work as a stand off and a chain tensioner.
Caution this is a untested idea, just a quick thought
thank you for posting your chassis it looks great,
Tim

This looks Great Brian.
I would disagree this will be enough to mount our electonics and phenumatics.
One worry that I agree with is the bumbers. Thanks for doing this.
From what I hear form jordan, Crossbracing the cornors would be a good ideal it would give some solid regidity. This can be ssen in our cornors of last years bot.
To finish it off it we can't decide what we will use for wheels until the game is anounced.

See you tomorrow.

Talk to Madison from 488 about their experience using Omni's in a traction 6 wheel drive. She's got some GREAT insight and experience there.

Otherwise, looks pretty good. Might want to work on using less material by means of design instead of CNC pocketing... I'm SURE you can achieve a lighter, stronger base with less machine time. Keep at it!
