It's one thing to take a picture of something and see how it works... it's quite another to design and manufacture <insert mesmerglobber here> and make it work for your specific application.
And for my specific purposes... take as many pictures of the robot controller as you like... I doubt many of them will help you figure out how the software works inside.
