I have the robot and I want to develop the system of its movements and position tracking. What is a good way to do this?
What about Kallman filter? Did you try it? Kallman filter is used for moving objects tracking. It can be initialized by using only a cropped image of what you want to track and then you have an adaptative version that just slightly changes the appearance of the tracking target with time and so should be able to keep tracking the rover when it’s pivoting.
