Updating the NAO system using Choregraphe may failed (may occurs only if the current NAO system version is 1.12 or greater).
The error code tab is given hereafter:
| Error code | Meaning | Solution |
|---|---|---|
| 1 | Internal error. | Retry. |
| 2 | Internal error. | Retry. |
| 3 | Internal error. | Retry. |
| 4 | Unknown hardware. | Make sure the target is a real NAO robot. |
| 5 | Image does not match the target hardware, i.e. NAO v4 (Atom) image on a NAO v3.x (Geode) robot and vice versa, or a NAOqi SDK, or anything else. | Check the given file is an image, then retry. |
| 6 | Write error. Cannot write the image on the robot. | Check that there still is enough freespace on the robot. An upgrade needs about 200MB. |
| 7 | Checksum check failed. | Check the given file, then retry. |
Choregraphe does not work with all the 3D card. If it crashes at start up, it probably means that there is a conflict with your 3D card. Please update your graphics card driver and try again. If it does not work, you will see a pop up with an Internet link to the supported graphics card. You should check it out (http://www.ogre3d.org/tikiwiki/Hardware).
You have created a behavior. It is not yet operational. Here is how you can fix the bugs. That it is only possible if the current behavior is playing.
To control a behavior you can: click on Play to load it on the robot. You can double-click on an input or output to stimulate it.
The small eye next to each layer allows you to “mute” a layer: it will be ignored when the behavior is played. This can be useful when you want to debug your behavior.
Go to the web page of the robot. The modules running on NAO are listed. You can see the details by clicking on their name.
Each time the link between 2 boxes is simulated, the color of the link changes. It is a good way to check the execution.
When a box has a value as output, the last value displays in the Tooltip.
self.logger is standard Python logger created with the Python module Logging.
The log information can be categorized by level of severity (each level has its associated font color in the debug window):
In your Python script, we recommend you to add warning, error and critical logs to inform when you behavior dangerous or erroneous state.
You can also use info and debug to trace execution flow of your behavior.
Open the script of a box.
Add the self.logger line in a function as below:
def onLoad(self):
self.logger.debug("Loaded box %s", self.getName())
In the Debug window, select the minimum level of information you want, Debug in our case.
Execute the box.
All debug message display in the debug window to let you understand what is going on. The potential debug, info, warning, error and critical messages of other functions also display as the minimum level asked is debug.
If you choose error, you see only error and critical messages.
In version 1.12.0 and previous ones, Choregraphe could have created temporary directories in a wrong path where the Windows Cleaning disk command hasn’t access.
Those directories, named alprojectXXXX_X, can be safely manually removed from disk.
Their most common locations depend on Windows version:
on Windows XP:
C:\Documents and settings\[username]\Local Settings\
on Windows 7:
C:\Users\[username]\AppData\Local\
Where [username] is your own user login.
