How to creat a topic of path and show it in Rviz for Manipulator?

edit

I'm pretty sure this is a duplicate (one of many), but I can't find anything now, so take a look at ros-planning/moveit_visual_tools.

are you have any idea? @@

I'm not sure I understand what you're trying to say.

moveit_visual_tools provides publishers to visualise trajectories. As far as I understand your question I believe that is what you want to do, is it not?

sorry, my Eng isnt good. I want to creat a simple trajectory of end-effector of robot arm such as: point to point. But i dont have any idea for this.

For (full) motion planning: see MoveIt.

For visualisation of trajectories, you could use moveit_visual_tools.

is it support python?@@

MoveIt? Yes, partially. moveit_visual_tools? I don't know.

thanks so much
