- | If you've ever driven a tank, these equations probably make sense. But we're interested in the "inverted" equations. We want expressions for the left_wheel and the right_wheel in terms of rotation and translation. That is, we already know how we want our robot to rotate and translate -- these are the outputs of our PID controllers. So rotation and translation are our **knowns**. Our **unknowns** are left_wheel and right_wheel. Using some algebra, we get the inverted equations. | + | If you've ever driven a tank, these equations probably make sense.
