def actionlib.action_client.ActionClient.wait_for_server | ( | self, | |
timeout = rospy.Duration(0.0) |
|||
) |
Waits for the ActionServer to connect to this client.
Often, it can take a second for the action server & client to negotiate a connection, thus, risking the first few goals to be dropped. This call lets the user wait until the network connection to the server is negotiated
