Starting a design for a rover unit using 2 wheel chair motors with typical setup of a saber tooth controller and arduino microcontroller. I get how I can use “tank steering” using the mixed mode and writing code that just moves one motor vs the other and that will rotate the rover to point in different directions.
My rover will be traveling down a long driveway with curves and will use video processing to keep it centered. What I’m not seeing is how to make small left-right movements with the motor controller. Do I have to handle this in my arduino code to set different speeds of the 2 motors for small turning motions? The saber tooth docs show a “left-right” in the second channel in some modes and I’m wondering if it has the functionality to handle differential speeds to steer.
