You can connect Choregraphe to this robot.
The contextual menu offers also the following options:
A Simulated robots :
NAOqi is running on a computer .
You can connect to this kind of robot.
But you cannot view its webpage nor test its LEDs.
The connection to Choregraphe’s local NAOqi is automatically done when you execute Choregraphe. This local NAOqi does not appear in the robot list, as the connection is not a network connection. However, a reconnection to this NAOqi can be done through the menu Connection > Connect to virtual robot .
My robot does not appear in the list ¶
Mac only : a known issue prevents the display of robot’s list.
- Use the Use fixed IP/hostname instead.
Windows / Ubuntu : make sure your robot is:
For further details, see: Turning NAO on or Turning Pepper on .
Connected to your network.
For further details, see: Setting NAO’s WiFi connection .
I cannot connect Choregraphe to my robot ¶
If you cannot manage to connect to your robot using the list, you can connect directly to its IP address and its port:
- Select the checkbox Use fixed port , then fill in the field with its port (9559 by default).
- Select the checkbox Use fixed IP/hostname , then fill in the field with the IP Address (that you can get by pressing once on the Chest button of your robot).
- Click the Select button.
I got a synchronization error while sending my behavior to my robot ¶
If your robot had rebooted while Choregraphe automatically reconnected to it, a failure can occur when sending the current behavior. As a consequence, the robot is disconnected and the behavior is not sent.
Simply reconnect the robot manually and you will be able to send your behavior again.
Connection troubles ¶
In case of connection troubles on Windows, Mac or Linux, try the following in order to find out the reason:
Launch Choregraphe with the option –no-naoqi
If it solves the problem, you should keep using the option –no-naoqi.
It seems that the NAOqi embedded in Choregraphe is corrupted. Nevertheless you can connect Choregraphe to NAO. You can also simulate your behavior by launching manually naoqi from choregraphe_install_dir/bin/naoqi.
Test without your firewall.
If it solves the problem, you should review your firewall configuration for Choregraphe application:
2.1 Open the firewall configuration (on Windows Configuration Panel > system and security > Firewall > Authorized programs)
2.2 Remove all the choregraphe-bin references
2.3. Relaunch Choregraphe
Linux or Mac only : configure the ‘ssh known hosts’.
If you can’t connect to your NAO with ssh (
You should remove the line referring to your robot in the file
Try with a local NAOqi:
5.1 Launch Choregraphe with the option –no-naoqi -vd
5.2 Launch naoqi on the same computer (from choregraphe_install_dir/bin/naoqi)
5.3 Connect Choregraphe to this naoqi (IP 127.0.0.1 PORT 9559)
If it fixes the problem, you certainly have some troubles on your own network configuration.
Ensure that NAO can connect to Choregraphe:
6.1 Connect to your NAO (with ssh or putty).
6.2 Try to ping your desktop computer IP from NAO.
6.3 Open a python shell on your NAO and create a proxy to a naoqi running on your desktop. For instance:
If one of those two points fails, you certainly have some troubles on your own network configuration.
Open the required ports in your network configuration:
Choregraphe - NAOqi : 54010, 54011, 54012, ... ( as many as you have Choregraphe/Monitor instances running on the same computer).
Choregraphe - ftp : 20, 21
Choregraphe - log : 50998, 50999
Choregraphe - bonjour: 5353
NAO - webservices : 5222, 5223
