Environmental and Ethical Analysis: The True Costs
TEAM 12 - SUPER TANK
OVERVIEW
Project Refresher
A Basic Question
An Ethical Look (Qualitative)
Environmental (Quantitative)
A Personal Perspective
PROJECT REFRESHER
Long Range Vehicle (Tank) Control over wireless network
Operate from anywhere in the world (Website/Android App)
Collaboration with HKUST
Shared Server
Customizable for new vehicle features
PSSCS
An ability to send/receive/decode commands from a controller wirelessly
An ability to control direction/firing capability of a vehicle
An ability to autonomously avoid obstacles encountered by the tank
An ability to provide sensor feedback to a wireless controller
An ability to monitor a battery and prevent unexpected signal loss by alerting operator
A BASIC QUESTION
SUPER TANK

?
ETHICAL QUESTIONS?
NONE!
ETHICAL QUESTIONS
Will this be used to hurt anyone?
How secure does it have to be? Can it be hacked by terrorists?
Who should we allow to use SUPER TANK?
Etc..
Not the focus of this analysis.
INDUSTRIAL CASE - We’ll assume DARPA hired us for honest reasons to deploy the SUPER TANK
RESIDENTIAL CASE – We’ll assume we are producing a toy.
ETHICAL IMPACT
How thoroughly tested should this be?
What regulations should we comply with?
Where should we add warning Labels?
User manual cautions?
Should we add any additional safety mechanisms?
ETHICAL IMPACT
What regulations should we comply with?
It should be FCC Class B compliant.
How thoroughly tested should this be?
All FCC Class B features
Potential injury from cannon
External pinch points of motors
Reliability of all functions related to PSSCs
ETHICAL IMPACT
Where should we add warning Labels?
If cannon can injure: On chasis
User manual cautions?
If cannon can injure
Should we add any additional safety mechanisms?
Physical safe gaurds against motor pinch points
ENVIRONMENTAL IMPACT?
ENVIRONMENTAL IMPACT CONSTRAINTS
We are in the Residential market space
No evaluation of Network
Just Purdue’s Vehicle

EPA.gov -> 16.0 Tons CO2/year
Averaged is 15.35 Tons CO2/year
MY PERSONAL CARBON FOOTPRINT
Estimate I will live to be 85.
Estimate my standard of living will increase at 3% per year
Estimate standards of living are proportional to your Carbon Footprint.
