the issue is this

  • [problem definition] path_tracking behavior transforms the points to controllers' frame_id. But it does it only once. When drift happens it doesn't recognizes the drift.
  • [solution] path_tracking behavior should transform the process_values to its own frame to keep track of the heading.
    • If it publishing waypoints on map, it should transform the vehicle position to map: cg_link to map.
    • It should compute the heading and distance according to this new points, and it should transform it back to cg_link.
    • It should do so on every iteration.
      at the same time,
  • MVP Control should be able to accept control inputs on different frames.
