|--\___/--|
|oo-----oo| Back
________

(This is not to scale, the little - just is a space, so ignore them))

Okay the circles are the wheels, the back four wheels in the back will be powered on a chain, and the front two wheels will be none powered and will be held in a straight position, not free on a caster mechanism. Before our team dives into creating this, I was hoping for some feed back, this is essentially 2 back wheel tank drive. So here are my questions?

1) What advantages do you see with this drive?
2) Should the front and back wheels be powered or just the back ones?
3) is there a thread, or some specifics to way a tank drive is bad for this competition?
4) With the layout above, where would you put the wheels, which ones would be powered, and what kind of drive would you recommend for this base layout?

TY so much to all who respond, are team is rly in a fix on this, and can't rly decide, and answering these questions, would help us SOOO much, ty again!

1.Not to be crazy harsh, but i see just about no advantage to this drive
2. You need to power every wheel touching the ground this year. Depending on how your weight is displaced, you will be giving up tons of traction by not powering wheels. For example if you have around 20% of your weight over the middle of the bot, you could be losing upwards of 20% of your traction, which is a lot in this game.
3.Ill tell you right now why. The latteral coefficient of friction is nearly twice that of the normal CoF.
