Very nice looking machine you got there!

I am curious about the two pairs of smaller outside wheels. My team wanted to create a 10 wheel drive with two pairs of raised smaller-diameter outside wheels, very much like the ones on your bot. However, we couldn't get an appropriate sprocket ratio to power those wheels and thus decided against it.

Are you accommodating for the differences in linear velocity due to the different diameters of the wheels with sprockets? With my eyes, it seems that there is a larger sprocket on the larger wheel and a smaller sprocket on the smaller wheel. That seems counter-intuitive to what I would imagine, as I thought that you would need a larger sprocket on the smaller wheel to increase its linear velocity.

Anywho, VERY nice looking 'bot! Congratulations on the two regional wins as well!
