How to wake up your NAO¶
To wake up NAO:
Click the 
Wake up button in the toolbar.
Why do I need to wake up NAO¶
Wake Up means set the Stiffness of all motors on. Additionally, if the robot is crouched, he also goes to the StandInit posture.
In Choregraphe, set the Stiffness or “enslave” is the action to provide power to the motors of your robot. When your NAO is not stiffened, its limbs are soft like a puppet, its motors do not have power. To execute behaviors and see the result on your connected robot, you have to stiffen it, giving power to the motors.
To go further¶
It is also possible to set the Stiffness, during the execution of a Behavior, to an intermediary value, as all actions don’t require the same strength. To do so, add the Set Stiffness box to your Behavior.
