Looks like you didn't install navfn? Or did not configure it as a plugin. How does your parameter file look?

2 years ago Thank you very much for replying to me, I have solved this problem, I would like to ask again, I put this plug-in in move Base alone, after getting the global path, I will track the path with PID. If I want to track the path and avoid obstacles in the track path, what should I do? Do you have any suggestions or your feature pack that can
achieve path tracking and obstacle avoidance? Thank you!

2 years ago You cannot avoid obstacles with the PID. It's sole function is to track the path exactly. Avoiding obstacles would deviate from that purpose. In that case most other local planners will probably do!

2 years ago Is there any mathematical principle derivation and blog recommendation for full path coverage in your feature pack? I would like to learn the mathematical principle first and then look at the code, thank you!Is there any mathematical principle derivation and blog recommendation for full path coverage in your feature pack?

Seems like you did not configure a local planner? What does your yaml file look like?
