Hi, Thanks for your code. I compile this pkg successfully, however I met a issue when running the pkg using your launch file.

ERROR: cannot launch node of type [hybrid_a_star/run_hybrid_astar]: Cannot locate node of type [run_hybrid_astar] in package [hybrid_a_star]. Make sure file exists in package path and permission is set to executable (chmod +x)

Can you help me sovle this issue please? Thank you.

I'm very sorry, I deleted an important ros command due to my carelessness. The bug has now been fixed, please try to update your code, thank you for your feedback.

Thank you for your reply. Although this error is eliminated, there is not any path generation after I set the start point and goal.

zm0612 commented 2 years ago

Hello, is this the same every time you choose the start and end points? Sometimes if the start and end points you choose are too close to obstacles, collision detection will be triggered and path search will not be possible.

zzhh00 commented 2 years ago

You are right. I try the different start and end points and the path is generated successfully. Thank you.
