TL;DR Summary
The Sumo robot is designed with two wheels (motors), each of which can be adjusted separately (giving each its own speed). By combining several facts, it is possible to mathematically describe the movements and obtain a mathematical model.
Greetings readers! I am writing this post because I have a problem and I cannot proceed further. My task is to develop a mathematical model designed to plan the movement of a sumo robot, or x=AX + BX, where all are matrices and AX are the matrices of new coordinates, while BX are the control matrices.

In this image, I have schematically drawn the schematic diagram of the entire robot and part of the ICC theory.
So the equations I have written would be like this. (Unfortunately I can't find how to insert latex into this page)

So the final mathematical model should be like this. However, after testing, it doesn't get the correct next values, and I don't know why. Maybe someone can help?

Take a look at the handy "LaTeX Guide" at the bottom left of this post.
 
Thread 'Direction Fields and Isoclines'
I sketched the isoclines for $$ m=-1,0,1,2 $$. Since both $$ \frac{dy}{dx} $$ and $$ D_{y} \frac{dy}{dx} $$ are continuous on the square region R defined by $$ -4\leq x \leq 4, -4 \leq y \leq 4 $$ the existence and uniqueness theorem guarantees that if we pick a point in the interior that lies on an isocline there will be a unique differentiable function (solution) passing through that point. I understand that a solution exists but I unsure how to actually sketch it. For example, consider a...
