Thank you everyone for your help so far. I will look into the different sensors and the agorithms posted.

Many teams have also used belts for steering because, as you said, they don't stretch, and they also give more precise motion transfer, useful for steering modules precisely. They are however more expensive and probably heavier.
I guess I know that intuitively that turning is easier with a wide base, but what is the reason behind that?

Also, I believe you are right that belts are more expensive, but according to Cyber Blue 254 in their belt vs chain presentation, belts are actually lighter and more efficient.
