Hi there, I am currently using naoQi-sdk-1.14. I am also following the guide: http://www.ros.org/wiki/nao/Tutorials/Getting-Started

I am on the stage: 1.6: Launching ROS and NAOqi

When I execute the command:

LD_LIBRARY_PATH=~/naoqi/naoqi-sdk-1.14-linux32/lib:$LD_LIBRARY_PATH NAO_IP=127.0.0.1 roslaunch nao_driver nao_driver_sim.launch

I get the following error:

"Error importing NaoQI. Please make sure that Aldebaran's NaoQI API is in your PYTHONPATH"

The full output is shown below:

martin@martin-VPCEE2S1E:~$ LD_LIBRARY_PATH=/home/martin/naoqi/naoqi-sdk-1.14-linux32/lib:$LD_LIBRARY_PATH NAO_IP=127.0.0.1 roslaunch nao_driver nao_driver_sim.launch ... logging to /home/martin/.ros/log/3b3e0ce8-641c-11e2-b2a9-78dd08e5b016/roslaunch-martin-VPCEE2S1E-9508.log Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.

I have looked at similar questions and answers such as http://answers.ros.org/question/28902/adding-naoqi-api-to-pythonpath-v112/?answer=29878#post-id-29878.

I have added onto my bashrc file - export ROS_PACKAGE_PATH=~/my_workspace/nao:$ROS_PACKAGE_PATH and export PYTHONPATH=~/naoqi/naoqi-sdk-1.14-linux32/lib:$PYTHONPATH but i still get this error :S

Could anyone help please?

You don't need the naoqi-sdk-X.YY-linux32 but the NaoQI Python SDK for the ROS nodes, starting with NaoQI 1.12. So, don't add it to your LD_LIBRARY_PATH globally in your .bashrc (that may have other dangerous side effects).

You need to have the separate Python SDK in your PYTHONPATH, that alone should be enough. Here is what my entries in .bashrc look like:

export AL_DIR=$HOME/code/Nao/1.12.3
export PYTHONPATH="$PYTHONPATH:$AL_DIR/pynaoqi"

The directory ~/code/Nao/1.12.3/pynaoqi contains the files allib.py, allog.py, naoqi.py etc.
