Anyway, there are navigation algorithms in MRPT that can help you navigate from A -> B, given some sensor input. I guess the most popular one would be the reactive navigator: https://www.mrpt.org/tag/reactive-navigation/

If you 're using ROS, MRPT also offers ROS wrappers: https://github.com/mrpt-ros-pkg/mrpt_navigation

As far as I know though, either the reactive nav2d or the localisation nodes operate using 2D laser scans

Is it a set of given (x,y) coords?
bergercookie
OK, but how do you reach that (x,y) representation to feed to your algoirthm?
If you have that (x,y) representation and your estimated position from your GPS-like system then you can implement simple PID controllers for the x,y (and theta?) of your robot to follow those waypoints
bergercookie
Otherwise you have to "sense" where the line is relative to the robot and have some sort of feedback control loop to follow that line.
