    In Choregraphe, choose Connection > Connect to... in the menu bar

    or click on the connect-button Connect to button in the tool bar.

    In the Connection widget:

    • if the simulated robot appears in the list, double click it,
    • if not, set the IP address to 127.0.0.1 and port to 9559 and click the Connect to button.

  • a simulated robot evolving in a virtual world:

    See Webots for NAO documentation about Launching a simulated robot and Connecting Choregraphe to the simulated robot.

Type and state

Icon Type/State Description
../../_images/chore_robot_off.png

A real robot.

NAOqi is not running.

The robot is in a state in which it should be impossible to establish a connection. NAOqi has been shutdown or is in a state that doesn’t allow the connection.

Note

You can force the connection to this robot by enabling the option Use fixed port and then click on Connect to. It will try to solve the connection using this port (9559 by default).

or your custom buddy icon.

A real robot.

NAOqi is running.

You can connect Choregraphe to this robot.

The contextual menu offers also the following options:

  • View web page: Displays the webpage of the robot, where you can configure it (WiFi, name, NAOqi, ...). For further details about the webpage, see the section: NAO web page.
  • Test LEDs: Starts a little animation on the eyes of the robot. This enables you to confirm that this robot is yours.

A simulated robot:

NAOqi is running on a computer.

You can connect to this kind of robot.

But you cannot view its webpage nor test its LEDs.

Note

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.

Troubleshooting

My robot doesn’t appear in the list

Make sure your robot is:

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:

  1. Select the checkbox Use fixed port, then fill in the field with its port (9559 by default).
  2. 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).
  3. Click the Connect to 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:

Step Action

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 (ssh nao@IP), you may have troubles in your known hosts config.

You should remove the line referring to your robot in the file ~/.ssh/known_hosts or use the command:

ssh-keygen -R {IP or name of the robot}
Reinstall Choregraphe.

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:

from naoqi import ALProxy

log = ALProxy("ALLogger", DESKTOP_IP, NAOQI_DESKTOP_PORT)

log.info("python", "Hello from NAO")

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 - http : 80

Choregraphe - log : 50998, 50999

Choregraphe - bonjour: 5353

NAOqi: 9559

NAO - webservices : 5222, 5223
