I'm currently trying to simulate receiving images from the Nao camera, I've launched the nao_drivers with "roslaunch nao_driver nao_driver.launch" but on the node list nao_camera is missing. When I try to launch the node separately with "rosrun nao_driver" I get the following:

using camera:  0
Traceback (most recent call last):
File "/home/joel/Ros/nao/stacks/nao_robot/nao_driver/scripts/", line120, in <module>
File "/home/joel/Ros/nao/stacks/nao_robot/nao_driver/scripts/", line 91, in main_loop
img.height = image[1]
TypeError: 'NoneType' object has no attribute '__getitem__'
[INFO ] Stopping ALNetwork

Any help greatly appreciated

Well, somehow, the the object image, is a Python None-object. How is it created? At least the object is created, there would be an other error if is was not created at all. You can debug python code with import pdb; pdb.set_trace().

What method/functiuon is supposed to set image to some value?
