Hi! I am using this package in Turtlebot on ROS Noetic but I am having some errors to build a trajectory.
It shows this messages: "Path not valid for smoothing, returning", "No path found from the D* Lite planner". Could you help me ?

Hello, I successfully used this plug-in in move_base, but how can I use the function of dynamic obstacle avoidance? Is it ok to add some dynamic obstacles when the robot moves in the real world?Hello, I successfully used this plug-in in move_base, but how can I use the function of dynamic obstacle avoidance?

Your CMakeLists file needs the spencer_nav_msgs message type, however I can't get it. I've browsed https://github.com/spencer-project/spencer_messages and it really doesn't have it.

Hi! Thanks for your contribution.
For PathSplineSmoother::smoothPath2D() , I don't quite understand the principle of smoothing. Is there any relevant information that can introduce this part of code. I would appreciate it if you could provide me with the relevant formula.
