The values for the status of a goal are as follows:

  • PENDING - The goal has yet to be processed by the action server
  • ACTIVE - The goal is currently being processed by the action server
  • REJECTED - The goal was rejected by the action server without being processed and without a request from the action client to cancel
  • SUCCEEDED - The goal was achieved successfully by the action server
  • ABORTED - The goal was aborted by the action server
  • PREEMPTING - Processing of the goal was canceled by either another goal, or a cancel request sent to the action server
  • PREEMPTED - The goal was preempted by either another goal, or a preempt message being sent to the action server
  • RECALLING - The goal has not been processed and a cancel request has been received from the action client, but the action server has not confirmed the goal is canceled
  • RECALLED - The goal was canceled by either another goal, or a cancel request before the action server began processing the goal
  • LOST - The goal was sent by the ActionClient, but disappeared due to some communication error
