But, if you give a translation goal first, it moves normally, and from then on, it can rotate in place without a problem. Use path metrics and state validation to ensure your path is valid and has proper obstacle clearance or smoothness. It is fairly well supported and kept up-to- date, is has support for holonomic type drives and in comparison to the trajectory_planner that was originally being used, it allows for more freedom of movement.
