Turtlebot3 path planning
Hi everyone! I'm trying to build a path for turtlebot3 simulation, like in the figure, I want the robot keep roaming in the setting path, A->B->C->D->A->B->C->D->A->B->C->D-> ......
like in the figure, ( sorry I cannot upload file due to my low level account). image description
I don't want to do the 2d Navigation on screen, I want to build a script to let the robot move in the setting path. Please give me some help and suggestions. Now I have no clue about how to do it.
