Robot stands 2cm behind target (DWA Planner)
I am using DWA planner algorithm. When I go towards the target I gave in the RVIZ environment, my robot stays a few inches behind the target point and starts to spin around itself. It stops after a while.
The place marked in red is my target point. The green line is the path created in the DWA planner. What can I do to have my robot stop at that point?
