[Robotics] Image extraction from camera

[Gilberto Echeverria]

Hi Boris,

It is possible to do what you want using the VideoTexture module in 
Blender. Though bear in mind you need a decent graphics card for this 
method to work.
The description of the module is here:
http://wiki.blender.org/index.php/Doc:Manual/Game_Engine/Python_API/VideoTexture
As part of the MORSE simulator project, we have implemented camera 
modules for mobile robots. You can take a look at the project here:

And there is also a description of the camera module here:

All the best.

Gilberto
