some of noaqi robot need to use wakeup and rest for servo off all robots, http://doc.aldebaran.com/2-1/naoqi/motion/control-stiffness.html#control-stiffness
Also that robot is not able to change stiffness with "Body" , https://github.com/k-okada/nao_robot/blob/add_wakeup_rest/nao_pose/nodes/pose_controller.py#L162, 
Does someone know how to know the type of the robot through ALporxy interface?
