Noodles was intended to be modified to do whatever a player might want him to do, However, my organisation skills were lacking. So that you may easily figure out his mechanics...
Here's how he works;

There are three main areas where the controls live;

The "Frames" timer block loop
These three timer blocks control the arm sway, and the semi-random headlight. They can be set up to move the head and body, and the first version of this robot did so.

The "ICU" controllers
The ICU or "I see you" controllers determine what Noodles will do if he catches sight of ye. By default, he makes a wonderful beep noise and turns on the camera; turning on the light. You can do other things with this too. Noodles also stops looking around the room and turns to look at you.

The Custom Turret Controller
The turret controller is what I use to track a player, much like a gyro missile does. Upon seeing you, Noodles will trigger the ICU controller, and when he cannot find you, he triggers the IDontCU controller. Poor Noodles.

Anyway, This probably wasn't necessary, but there it is, I just love documentation. If I've forgotten anything, I'll update it when I have another look at him for reference.

Version 2 will be finished at some point in the next millennia, although I should warn, Noodles V2 isn't tied to the ground, and so isn't as traditionally useful as his older brother.
