MoveGroupCommander unable to connect

Hallo, So, my setup is based on: - http://docs.ros.org/indigo/api/moveit_tutorials/html/doc/pr2_tutorials/planning/scripts/doc/move_group_python_interface_tutorial.html - and on package, which I generated with the moveit wizard. The wizard gives me a demo.launch file, which is okay, I can run it. But as soon as I run my node, based on the code above on a different namespace with a launch file I am getting this error: > RuntimeError: Unable to connect to> move_group action server 'move_group'> within allotted time (5s). Starting my node in the launch file looks like this: My python file: name = rospy.get_param("robot_name", "move_it_robot") rospy.init_node(name, anonymous=True) try: rospy.wait_for_service('/move_group/load_map', 1) except ROSException: rospy.logerr("Please start MoveIt first") rospy.wait_for_service('/move_group/load_map') moveit_commander.roscpp_initialize(sys.argv) moveit_commander.RobotCommander() moveit_commander.PlanningSceneInterface() global group group_name = rospy.get_param("move_group_name", "welding") group = moveit_commander.MoveGroupCommander(group_name) What am I missing here? **Please note**: I can run my node on the global namespace (removing ns from the launch file), then it is working fine, but moving it to a specified namespace makes it crash. Thanks in advance!
