True enough, and I have given much thought to different drive configurations.................................... ......................................... My favorite (4 treads):....Another idea (3 treads):...........Killough (3 treads):

Realistically, these will take time and money to make, so I am thinking about this for a test platform (2 treads, 2 omniwheels working in tandem):

To have the best performance on the field, you would have each tread independently controlled. Just to throw another idea onto the field, what if you used four DeWalt 3-speed shifters with FP motors, and had a 3-speed omnitrack robot? That would be incredible.

Why consider omnitreads at all? Two words: Freaky Mobility.

I am having problems attaching images. Periods represent blank spaces. Sorry.
