So as any logical person would do with a robot that can be programmed to do anything. I add the ability to detect and recognize faces.

After some experimentation I add the code into the robot. Which makes it run so slow I can no longer drive it.

So, after reducing how many times the recognition runs the robot becomes drive-able again. I also add the ability to save any faces currently in the view of the robot. 

Later I add a slightly better way of importing faces, with a file (faces.txt) that links the name with the file of their face. The program on startup reads the file and processes it.
