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

MY PERSONAL CARBON FOOTPRINT

Conversation.org -> 14.7 Tons CO2/year

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.
