Week 3 HW: The System Diagram

1. Consider the original Edison electric bulb, as well as the Philips Hue bulb. Diagram the 5 system elements in each case. What additional system(s) has to be present for the Philips Hue to work? Can you diagram it? 
2. Consider self-driving cars. Identify (& diagram) the 5 system elements needed for self-driving cars to work? If you have a choice between making very smart or somewhat less-dumb roadways, which would you choose & why? How would you improve safety?
3. Identify the Packaged Payload in (B). How do you make money if you’re Ford? How do you make money if you’re Google? Is the packaged payload the same? 

Edison Light Bulb System Diagram
Source: Power plant to generate electricity
Distribution: Power lines to bring electricity to the light bulb
Packaged Payload: Electrons in the wires of the power lines
Tools: Physical filament in the light bulb that receives the electrons
Control: The original light bulb system had no control system, but meters were soon implemented by Edison to control the amount of electricity that goes to each business or residence

Phillips Hue System Diagram
Source: Power plant to generate electricity
Distribution: Power lines to bring electricity to the light bulb
Packaged Payload: Electronics in the wires of the power lines
Tools: RGB LEDs in the light bulb that illuminate with an applied voltage
Control: Electricity meter, but also an integrated app that allows control of the brightness of the bulb, the color of the bulbs, and the timing for the illumination of the bulb.

Self-Driving Cars Diagram
Source: Factories that produce the cars (if manufacturer) or engine that runs the car (if examining driving behavior)
Distribution: Shipping used to send the cars from the factories to the dealerships (if manufacturer) or crank shaft that converts the chemical energy in the engine into rotational mechanical energy that drives the wheels (if examining driving behavior)
Packaged Payload: Individual cars being shipped (if manufacturer) or bursts of energy being provided to the drive train of the car (if examining driving behavior)
Tools: Buyers who purchase the cars from the dealership (if manufacturer) or drive train of the car that accelerates and maneuvers the vehicle (if examining driving behavior)
Control: Logistical systems to control and streamline the manufacturing and shipping process, could include automated factories in the source stage (if manufacturer) or AI system that accepts sensory inputs including LIDAR and camera feed to determine where the car should drive and what it should do (if examining driving behavior)

In the self-driving cars diagram above I separated it out into two distinct sections with the manufacturer representing Ford and the control of the driving behavior being Google. They each have a different packaged payload that they can make money off of because Ford makes money for each individual car that they ship from the factory and sell to a dealership and Google makes money on licensing out their AI control systems that control the driving to companies such as Ford or other manufacturers.
