Root Cause

Nav2 behavior tree action fails. Root cause varies: costmap not ready, planner timeout, controller stuck.

generic

Workarounds

  1. 90% success Check Nav2 logs for the specific BT node that failed 
    ros2 topic echo /behavior_tree_log
  2. 85% success Verify costmap is populated (not empty) before navigation 
    ros2 topic echo /local_costmap/costmap --once
  3. 82% success Test individual Nav2 components (planner, controller) separately 
    ros2 action send_goal /compute_path_to_pose nav2_msgs/action/ComputePathToPose ...

Dead Ends

Common approaches that don't work:

  1. Restart Nav2 stack on every failure 78% fail

    Restarts are expensive and lose all accumulated costmap data; hides the actual navigation issue

  2. Increase all timeouts to very large values 80% fail

    Masks configuration errors; robot sits idle for minutes before finally reporting failure

  3. Replace the entire BT XML with a simple sequence 85% fail

    Loses recovery behaviors, replanning, and fallback strategies
