# Thread: Ratio of Left Wheel to Right Wheel Based on Coordinate Data

1. ## Ratio of Left Wheel to Right Wheel Based on Coordinate Data

Hi,
How do I find the ratio of rpm of the left wheels to the right wheels given that I know the (x,y) coordinates of the points? Imagine that I have a car, and I want to go through all the points below. From the point I am on, how do I know the ratio of the left wheel to right wheel rpm to get to the next point?

Thanks!

2. Well, for average rpm, I would suggest getting the distance each tyre (left side and right side) does, then, dividing the distance by the circumference of the tyre...

Hmm, yeah, but I am really looking for the values I should put to the left/right wheels so the car will turn ande go through the next point.
