Re: Crab drive steering

In our situation, because two wheels are linked, Ackerman angles cannot be achieved....so we're most like Figure 1. Because left and right drive are independent we do slow down the inside wheels with respect to turning angle.

A real monster truck is probably most like Figure 2.
