## Launching an Activity

Prerequisite

Autonomous Life: ON - Basic Channel: ON - Installed Activities: Yes

To start an Activity:

Step | Action
--- | ---
| Make sure NAO is listening. For further details, see: Talking with NAO.
| Say: “Start” + the Activity name, or one of the Trigger sentences, if any. NAO automatically starts the corresponding Activity.

## Exiting an Activity

Prerequisite

Autonomous Life: ON - Basic Channel: ON - Installed Activities: Yes

To stop an Activity currently running:

Step | Action
--- | ---
| Lay your hand on NAO‘s head: palm on the top camera, and fingers on the head tactile sensor
| Hold your hand there for 1 second. Feedback: a slight sound: “blop”
| Quickly remove your hand to stop the activity. Feedback: “click” sound, and eye and status LEDs become green for a short moment
Result | After you remove your hand, the current Activity is stopped.

## NAO has fallen

If, for any reason, NAO has fallen on the floor, don’t worry!
The current activity is automatically stopped and NAO tries to stand back up on his own.

NAO tries to recover the last stable posture he was in (sitting or standing) and will not stop trying until this posture is recovered.

When a try fails, NAO removes its Stiffness so a human can put NAO in a more favourable position, (sit or crouch) so NAO’s next attempt will be successful.
