That is to say: the diagonal speed will be ~140% of either pair of wheels' speed.

See:



I imagine that this drive base would be quite tippy given the small base of support. The setup below is more common because the base of support is larger, and the fastest drive speeds are now aligned with the major faces of the chassis.
