I'm using the pre-compiled packages (sudo apt-get install ros-hydro-nao-robot) and not was installed the "camera-info-manager-py just the "camera-info-manager". And now with the image_view I can watch the retrieved image. Thank you so much Armin!

"No module named camera_info_manager". Is it correct the way I'm launching the nao_camera node? or I need to past some extra parameters?

$ I am able to use the Python Nodes with the robot NAO using:

$ export PYTHONPATH="$PYTHONPATH:$HOME/path/to/pynaoqi/"

and

$ roslaunch nao_driver nao_driver.launch force_python:=true nao_ip:=192.168.1.206

if I want to check which nodes are running:

$ rosnode list

and I obtained the next list:

/nao_behaviors
/nao_controller
/nao_leds
/nao_sensors
/nao_speech
/nao_tactile
/nao_walker

How can I start or launch the nao_camera, because I going to need the image since i work in Computer Vision? I tried with:

$ roslaunch nao_driver nao_camera.launch nao_ip:=192.168.1.206

but I got the next error: (copy-paste of the terminal)

I will really appreciate any advise, thank you!

Thank you for your time Severin! I'm going to continue using the python nodes. Now I don't know how to start the nao_camera node?. I will put in another question.

NAO with ROS, Following the tutorials and searching in the forum I found there are 2 main options: 1- ROS on a remote PC and 2- ROS directly on the robot. But, for the option 1, also there are 2 more options: 1.1 Python nodes (install precompiled binaries) and 1.2 C++ nodes (source install from repository). In my case I finally could installed and tested the 1.1 option. For curiosity and to learn more about ROS I want to tackle the 1.2 and 2 options. The questions are: What are the advantages and disadvantages of these 3 options? Which is the better option? Why? Sorry for my question! but, in my specific case I was lost in the 1.1 and 1.2 options while I was following the respective tutorial.

Thank you!

Armin, thank you for your advice, right now I'm able to launch the python nodes with the same instruction that you suggested in the above question ( roslaunch nao_driver nao_driver.launch force_python:=true nao_ip:=192.168.1.206) without any error and i tested a simple forward motion of the Nao.

Quinton, our problem is the linking with the pynaoqi (export PYTHONPATH="$PYTHONPATH:$HOME/path/to/pynaoqi/") in my case i have an error in the path to pynaoqi. now I have other problem when i launch the NAOnodes (ERROR: cannot launch node of type [nao_driver/nao_sensors_cpp]: can't locate node [nao_sensors_cpp] in package [nao_driver]) .

Hi! I have the same poblems, No handlers could be found for logger rosout. My configuration system is similar (ubuntu 12.04 64, ROS hydro and pynaoqi 1.14.5) for the Installation of ROS for NAO I followed the Armin's tutorials "ROS on a remote PC" but I installed just the precompiled binaries. should I uninstall them and install the github ones? including the extras_nao? Quinton Anderson, did you solve the problem? thank you!
