Preface:My Interest in the Topic
I first became really interested in robot ethics when I saw a soccer game at the Neurosciences Institute involving robots.
Although I felt that even I could beat one of the robots in a soccer game, I realized that they would only get better and I would only get worse.
I felt I had seen the future. Video

Overview
What is a robot? Why is RoboEthics important? What ethical guidelines should
govern the behavior of robots?

Robot:The Origins of the Word
The word "robot" first appeared in Karel Čapek's science fiction play “R.U.R.” (Rossum's Universal Robots) in 1921, first produced in New York in 1922.
It quickly replaced other words, such as “android.”

Robots as Autonomous Agents
Our definition of “robot” is in part stipulative, i.e., we can decide precisely what it means.
For the purposes of this presentation, the essential characteristic of robots will be that they are autonomous agents, i.e., they make decisions on their own based on a combination of programming and current input.
They do not need to look like human beings. They are not remote-controlled machines, for
such machines lack the key characteristic of making their own decisions.

Help at Home
“Someday, robots could replace humans as nurse's aides, but first they will need a little sensitivity training. Japan's Ri-Man is headed in the right direction. With sensors that enable it to see, smell and hear its environment, it also has some 320 pressure points on its arms and chest that allow it to sense the exact position of whatever it's holding. The bot can lift 80 lbs. today, but researchers hope to strengthen the motors in Ri-Man's arms without increasing their size, so they still resemble those of a man, not a monster. “Time, November 13, 2006Inventor: Bio-mimetric Control Research Center at the Institute of Physical and Chemical ResearchAvailability: Not for saleTo learn more visit www.bmc.riken.jp/~RI-MAN/index_us.html

Military Robots: BEAR“The Battlefield Extraction-Assist
Robot (BEAR), developed for military search-and-rescue
missions, has hydraulic arms that can support injured soldiers
weighing up to 400 lbs. (more than most troopers in full gear) and a
system of wheels, tracks and joints that enable it to maneuver in
all sorts of positions. It can balance on its back wheels to
climb up a steep hill or roll over rough terrain while staying low to
the ground. For now the BEAR needs a human to drive it via
remote control, but a more autonomous version is in the
works.”--Time, Nov. 13, 2006

Talon
TALON is a powerful, lightweight, versatile robot designed for missions ranging from reconnaissance to weapons delivery.

Robotic Combat Planes
X-45 Robotic Combat Plane Makes Dramatic Debut - The Boeing Co.'s X-45, the first robotic plane designed specifically to fly combat missions, has successfully made its maiden flight.

The Predator
The Predator is still remote controlled rather than autonomous, but now can carry weapon systems as well as perform recon.

The Future of Responsibility
When robots make decisions, who is responsible if they cause harm?
04/12/23 ©Lawrence M. Hinman 17
Deontological Approaches
Are there any categorical imperatives governing the behavior of robots?
The most well-known attempt at a set of such imperatives was Isaac Asimov’s Three Laws of Robotics.
04/12/23 ©Lawrence M. Hinman 18
Isaac Asimov's "Three Laws of Robotics"
“A robot may not injure a human being or, through inaction, allow a human being to come to harm.
“A robot must obey orders given it by human beings except where such orders would conflict with the First Law.
“A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.”

Gert’s Moral RulesThe Ten Rules 1. Don't Kill 2. Don't Cause Pain 3. Don't Disable 4. Don't Deprive Of Freedom 5. Don't Deprive Of Pleasure 6. Don't Deceive 7. Keep Your Promise 8. Don't Cheat 9. Obey The Law 10. Do Your Duty
How many of these rules would be observed in robotic weapons systems?

Questions for Deontological Approaches to Robotic Ethics
How do robots decide what is the appropriate description of an act?– For example: murdering a person,
killing a person, pulling the trigger of a gun, exerting pressure on a metal protrusion
If there are many rules, how do robots deal with conflicting rules?

Consequentialist RoboEthics
Consequentialist ethics in general maintains that the consequences of an action determine whether that action was good or bad.
Thus a consequentialist robot would be one whose actions are determined by weighing consequences.
04/12/23 ©Lawrence M. Hinman 22
Consequences for whom?
Egoist: consequences only for me Altruist: consequences only for
others Utilitarian: consequences for
everyone equally Group consequentialist:
consequences for my group (nation, family, fellow believers, etc.)
04/12/23 ©Lawrence M. Hinman 23
The Epistemology of Consequences
As James Gips argues in “The Ethical Robot,” judging consequences requires a daunting set of cognitive skills:
“A way of describing the situation in the world;
“A way of generating possible actions;
“A means of predicting the situation that would result if the action were taken;
“A method of evaluating a situation in terms of its goodness or desirability.”

Conclusion
Few answers, many questions: Autonomous robotic systems will be increasingly
common What ethical rules should govern their behavior? Are they sufficiently sophisticated to interpret
such rules properly? As the possible harm caused by robotic systems
increases, especially with robotic weapons systems, what limits should be placed on the autonomy of such systems? On their behavior?
