We ran power to our front wheels as well as back in 2014. Having your weight biased toward the back of your bot will help with turning if you have omnis in the front.

Sorry those are my desired dimensions, with the key problem being either dimension over 28. We may end up 38x38 or something else square.

Q: Why not six wheels ?
A: Because if we drop the stack while perpendicular to the platform bot isnt level and the stack might might tip over. Also want to straddle platform for precision.

Q: Why not 4 wheel tank ?
A: To get around the 28' limit the wheels need to deploy out and dealing with
drive belts adds risk and complexity.

Q: What about traction/stablity issues
A: If center of gravity is rear of center wont that minimize those problems ?
