This raises an interesting problem. Our *goal pose* is directly to the left of our *current pose*, and tanks cannot strafe (travel in the $$y$$ axis without turning). Luckily, to solve this problem we just need to know our error from the goal pose as a distance ($$\Delta d$$), and a heading ($$\Delta\theta$$):
$$
\Delta d = \sqrt(\Delta x^2 + \Delta y^2)
\Delta d = \sqrt{\Delta x^2 + \Delta y^2}
$$
