I am trying to understand how to create and follow a path with OMPL, and I tried to use the threaded script used in the 3DoFHolonomicPathPlanning demo but in a new scene, trying to move a cylinder from a start to a goal position, but I always get the same message:
[simExtOMPL:warning] OMPL: e:\ompl-1.4.1-source\src\ompl\base\src\planner.cpp:310: RRTConnect: Skipping invalid goal state (invalid bounds)
[simExtOMPL:error] OMPL: e:\ompl-1.4.1-source\src\ompl\geometric\planners\rrt\src\rrtconnect.cpp:252: RRTConnect: Unable to sample any valid states for goal tree
For now I only want to create and visualize the path, but it doesn't work. I've read in the forum that it may be a collision problem, but the only object in the scene is the cylinder.

Re: OMPL warning: Skipping invalid start state (invalid bounds)
Hello,
could it be that the cylinder is very slightly colliding with the floor?
Can you post a minimalistic scene that illustrates this?
Cheers

Hello,
No, I've already thought about the object colliding the floor and it wasn't the problem.

Here is the scene.

This is because your target is out of bounds!
You specify a valid area or [-0.5;0.5] for x, and the same for y. Yet your target is located at {1.25,1.025,0.125}
