Hi all,
I ran into a problem when I ran python scripts where an actionlib
action client is intantiated right after the node a the
wait_for_server() function does not seem to work properly (it just
does not wait).
E.g.
if __name__ == '__main__':
rospy.init_node('test_manipulation')
# rospy.sleep(1.0)
trajClient =
actionlib.SimpleActionClient("r_arm_controller/joint_trajectory_action",
pr2_controllers_msgs.msg.JointTrajectoryAction)
if not trajClient.wait_for_server(rospy.Duration(10.0)):
rospy.logerr("Could not connect to actionserver " )
exit(1)
will return immediately with an error, even though I would expect it
to wait 10s. If I uncomment rospy.sleep(1.0), everything works always
as expected. Is there a more elegant solution to this?
