Beginning with Transforms $T_{1b} = (0, 0, -D)$ and $T_{2b} = (0, 0, D)$ we can extract their Adjoints: Then, we write Twist $V_b$ in each wheel frame where $V_i = A_{ib} V_b$, noting that $v_y = 0$ for a 2D system: Hence, we can extract wheel speeds $\dot{\phi_1}$ and $\dot{\phi_2}$: Using the above two equations, we can construct our motion equation matrix: where \(H = \frac{1}{r} \left[\begin{array}{ccc} -D & 1 & 0 \\ D & 1 & 0 \end{array} \right]\), To get our body Twist $V_b$, we compute the pseudo-inverse of H in $V_b = H^+ u$.
