Like this: On the homepage of the robot's control panel you click back and then Shutdown. The OS shuts itself down then turns off the robot. Does the robot send a power-off signal to its power board, like ATX?
Very likely. An Arduino can shut itself off using a Pololu power switch.
The user presses the Center/Select button to boot the robot from a fully off state. There is no dedicated "power" button on the panel.
Good to know, thanks.
This is another possibility.
How does it boot when the Center button is pressed?
Just a SWAG. But it turns on when a MOSFET or Transistor in the supply turns on which is done by the micro (or whatever). The start button shorts out the transistor/MOSFET turning on the micro which in turn turns on its power supply device. It then stays on until power is interrupted or it shuts it down.
How does it maintain its "soft" functionality (controlling the OS) when the robot's on?
What are you asking, I do not understand "soft" functionality?
Sends a signal to the CPU to navigate the OS
I still do not get it, how do you navigate the OS, it is an operating system that the processor is running. I think you are telling us that it starts some sort of process, if so what is that process?
Tells the OS to select the highlighted item
Just a button that can variously turn the thing on and off
on: press the button
off: press and hold, perhaps
AND
provide single short presses to anything watching the button during the on time
to do anything.
I think one of those circuits went by here recently, fairly simple mosfet holding relay kinda thing.
AmIRight?

It's like this: On: When off, press the center button.
Off: Return to home, press Back, then Shutdown.
The system can only force reset, not force shutdown. It can be done by holding the back and center buttons simultaneously.
