move_base error
helo guys.. this error came out when i run go to specific point python program... so how to solve it?
[ERROR] [WallTime: 1488902263.154618] Received comm state PREEMPTING when in simple state DONE with SimpleActionClient in NS /move_base
I'm having the same issue. Did you fix this?
I am not sure if this helps, but I found out that this happens when a new goal is sent. In my case, I was only interested in the plans and wanted the robot to carry on moving while I was computing plans for other goals. It just couldn't do it and a new goal being sent always resulted in preemption.
I met the same error. In my case, function move_base.cancel_goal() is called to cancel task when all goals have reached. That's to say, there are no tasks being performed actually when the function is called. So error occurs. I add a Boolean variable to mark whether a task is being performed.
