International Robotics & Automation Journal Mini Review Open Access Ethics in robotics and automation: a general view Abstract Volume 4 Issue 3 - 2018 Most robotics and automation scientists believe that many new aspects currently emerging in robotics and automation (R&A), and aspects that are expected to emerge in future, call for the development of new cultural, ethical and legal regulations that can face efficiently the most delicate issues that may arise in real practice. Over the last two decades the subject of ethics in R&A has received great attention and many important theoretical and practical results were derived in the direction of making robots and automation systems ethical. The purpose of this paper is to discuss the issue of ethics in robotics and automation, and outline major representative achievements in the field.

Sholem Asch: Now, more than any time previous in human history, we must arm ourselves with an ethical code so that each of us will be aware that he is protecting the moral merchandise absent of which life is not worth living. Rudolf Steiner: For everyone who accepts ethical norms, their actions will be the outcome of the principles that compose the ethical code. They merely carry out orders. They are a higher kind of robot. Daniel H Wilson: We humans have a love-hate relationship with our technology. We love each new advance and we hate how fast our world is changing…..The robots really embody that love-hate relationship we have with technology. Introduction Ethics or moral philosophy is a branch of philosophy that studies in a systematic way, defends, and suggests concepts of right or wrong performance. The branches of philosophy are metaphysics/ontology, epistemology, teleology, ethics, aesthetics, and logic. The branches of ethics are meta-ethics, normative ethics and applied ethics. Robotics and Automation Ethics is the branch of applied ethics which investigates the social and ethical issues of robotics and automation in the broader sense which includes all kinds of automated systems through the use of computer, information, communication, and control science and technology, and develops ethical methods for resolving them via the exploitation of traditional and novel ethical theories (such as deontological, utilitarianism, value-based theory, case-based theory, etc.) In particular, Robot Ethics (Roboethics) covers the entire range of ethical issues related to robot design, operation, and use. Today the central aim of robotics research is to create robots that possess full autonomy, i.e., the capability of autonomous decision making. Here is exactly where the major robo ethics issues arise. Actually, present day robots are still not fully autonomous. They are partially autonomous. At the lowest end they possess low level (operational) autonomy (i.e., autonomous execution of programmed operations without any human intervention), and passing from medium level-autonomy (functional autonomy), they approach the level of full autonomy (at which there is not any human intervention in decision-making, planning/scheduling, functioning, and action performing). The same is true for the issues of ethics, where we have several levels of morality, namely:1 a. Operational morality (moral responsibility lies entirely in the robot designer and user). b. Functional morality (the robot has the ability to make moral judgments without top-down instructions from humans, and the Submit Manuscript | http://medcraveonline.com Int Rob Auto J. 2018;4(3):229‒234. robot designers can no longer predict the robot’s actions and their consequences). c. Full morality (the robot is so intelligent that it is fully autonomously choosing its actions, thereby being fully responsible for them). But could a robot be ethical? As argued by many authors, the minimum requirements for a robot to be ethical are: a. complete ability to predict the consequences of its own actions (or inactions), b. a set of ethical rules against which to test each possible action/ consequence, so it can select the most ethical action, c. Legal authority to carry-out autonomous decision making and action, accompanied by associated liability (e.g.).1-9 Fundamental Ethics Questions in R&A The ield of R&A ethics was developed over the years by addressing fundamental general and speciic philosophical questions: General questions a. Are the general ethics principles suficient for facing the issues raised by R&A? The total answer is NO! b. Is there a need of a speciic ethics framework applied to R&A? The answer is yes! c. Is ethics applied to R&A an issue for the individual scholar or practitioner, the user, or third party? The answer here is ‘TO ALL”. 229 © 2018 Tzafestas.

Our aim here is to provide a short review of some major contributions. The term robo ethics, for robot ethics, was irstly introduced by G. Veruggio in the First Symposium on Robo ethics held in San Remo, Italy (Jan/Feb. 2004), and the irst ethical system in robotics was proposed by Asimov10, consisting of the so-called Asimov Laws. These deontological laws are anthropocentric (human-centered) in the sense that the role of robots is to operate in the human service, and imply that robots have the capability to make moral decisions in all cases. Roboethics concerns ethics that occur with robots, such as whether robots pose a threat to humans in the long or short run, whether some uses of robots are problematic, such as in healthcare or as killer robots of war, and how robots should be designed such as they act ethically. Very broadly, scientists and engineers look at robotics in the following ways:11 a. Robots are mere machines (surely, very useful and sophisticated machines). b. Robots raise intrinsic ethical concerns along different human and technological dimensions. c. Robots can be regarded as moral agents, not necessarily possessing free will mental states, emotions, or responsibility. d. Robots can be conceived as moral patients, i.e., beings that can be acted for good or bad. Veruggio deines robo ethics as follows: XXII. Which type of ethical codes is correct for robots and automated systems? “Roboethics is an applied ethics whose objective is to develop scientiic/cultural/technical tools that can be shared by different social groups and beliefs. These tools aim to promote and encourage the development of ‘ROBOTICS’ for the advancement of human society and individuals, and to help preventing its misuse against humankind.” Actually, roboethics shares many ‘crucial’ areas with computer ethics, information ethics, communication technology ethics, automation ethics, management ethics, and bioethics. Galvan2 argues that robots possess an intrinsic moral dimension because technology is not an addition to mankind, but provide a way to distinguish man from animals. XXIII. Who is responsible for actions performed by human-robot hybrid beings? Veruggio and Operto5 points-out that the principal positions of scientists and engineers about roboethics are: XXIV. Is the need to embed autonomy in a robot contradictory with the need to embed ethics to it? Not interested in roboethics: These scholars argue that the action of robot designers is purely technical and does not have an ethical or social responsibility. XVIII. If there are multiple rules, how do robots deal with conlicting rules? XIX. Are there any risks to create emotional bonds with robots? XX. Is it ethical to program robots to follow ethical codes? XXI. Is it ethical to create robotic nurses and soldiers? XXV. Are there any types of robot that should not be designed? Why? Interested in short-term ethical issues: These scholars advocate that Citation: Tzafestas SG. Ethics in robotics and automation: a general view. Int Rob Auto J. 2018;4(3):229‒234. DOI: 10.15406/iratj.2018.04.00127 Copyright: ©2018 Tzafestas Ethics in robotics and automation: a general view certain ethical and social values should be adhered by robot designers in terms of good or bad. Interested in long-term ethical issues: These scholars accept that robot designers have global and long-term moral responsibility (e.g., digital divide between societies). Asaro4 describes how it is possible to make robots that act ethically, and how humans must act ethically and take the ethical responsibility on their shoulders, and discusses the question whether robots can be fully moral agents. Wallach10,12 describes the three typical approaches for creating ethical machines and robots, and artiicial moral agents (AMAs) in general. These approaches are: a. Top-down approach in which the desired rules/laws/principles of ethical behavior are prescribed and embedded in the robot system. b. Bottom-up approach in which the robot develops its moral behavior through learning. This is analogous to how children learn morality (what is right or wrong) based on social context and experience from their family and human environment. c. Mixed approach in which proper combinations of the top-down and bottom-up approaches are followed. The ethical concerns of robot use include the following: Loss of privacy (guidelines should be developed to guard against robot misuse, e.g., when drones and robots collecting data enter our home). Safety issues (when robots work closely with humans). 231 Assistive roboethics/Ethics of assistive robots Assistive robots constitute a class of service robots which is focused on the enhancement of the mobility capabilities of impaired people (people with special needs: PwSN) so as to attain their best physical and/or social functional level, and have the ability of independent living.7 Assistive robots/devices include the following: a. Assistive robots for people with impaired upper limbs and hands. b. Assistive robots for people with impaired lower limbs (wheelchairs, walkers). c. Rehabilitation robots for upper limb or lower limb. d. Orthotic devices. e. Prosthetic devices. The issues of assistive roboethics have been a strong concern over the years the evaluation of assistive robots can be made along three main dimensions, namely: cost, risk, and beneit. Since these evaluation dimensions are contradictory we cannot get full points on all of them at the same time. Important guidelines for these analyses have been provided by World Health Organization (WHO) which has approved an International Classiication of Functioning, Disability and Health (ICF).19 A framework for the development of assistive robots using ICF, which includes the evaluation of assistive technologies in users’ life is described.20 A full code of assistive technology was released in 2012 by the USA Rehabilitation Engineering and Assistive Technology Society (RESNA),21 and another code by the Canadian Commission on Rehabilitation Councelor Certiication (CRCC) in 2002.22 Liabilty issues (with regard to who is responsible for errors or faults/failures during robot operation). Social roboethics or ethics of social robots Lin, Abney and Bekey8 present a number of contributions by world-wide researchers that address many of the questions listed above. Three comprehensive books on ethics of machines, robots, and information are the following: Capurro R et al.13-15 Two important books on the more general ield of techno ethics are those of Galvan2 and Tavani.16 Sociorobots (social, socialized, socially assistive, socially interactive robots) are assistive robot that is designed to enter the mental and socialization space of humans. This can be achieved by designing appropriate high-performance human-robot interfaces: HRI (speech, haptic, visual). The basic features required for a robot to be socially assistive are:7,23.24 Branches of roboethics The branches of roboethics are: Medical roboethics or health care robotics ethics This branch refers to medicine and health care assisted by robots.7,17,18 The initiation of medical ethics goes back to the work of Hippocrates who has formulated the well-known Hippocratic Oath, which requires a new physician to swear upon a number of healing gods that he will uphold a number of professional ethical standards. The fundamental ethical principles of medical roboethics involve irst of all the principles of the Charter of Medical Professionalism, namely: Autonomy (The patients have the right to accept or refuse their treatment). Beneicence (The doctor should act in the best interest of the patient). Non-maleicence (The practitioner should “irst not to do harm”). Justice (The distribution of scarce health resources and decision of who gets what treatment should be just.). Truthfulness (The patient should not be lied and deserves to know the whole truth). Dignity (The patient has the right to dignity). a. Understand and interact with its environment. b. Exhibit social behavior (for assisting PwSN, the elderly, and children needing mental/socialization help). c. Focus its attention and communication on the user (in order to help the user achieve speciic goals). A socially interactive robot possesses the following additional capabilities:23,24 I. II. Express and/or perceive emotions. Communicate with high-level dialogue. III. Recognize other agents and learn their models. IV. Establish and/or sustain social connections. V. VI. VII. Use natural patterns (gestures, gaze, etc.). Present distinctive personality and character. Develop and/or learn social competence. Citation: Tzafestas SG.

DOI: 10.15406/iratj.2018.04.00127 Copyright: ©2018 Tzafestas Ethics in robotics and automation: a general view Well known examples of social robots are: AIBO: a robotic dog (dogbot) able to interact with humans and play with a ball (SONY). KISMET: a human-like robotic head able to express emotions (MIT). KASPAR: a humanoid robot torso that can function as mediator of human interaction with autistic children.24 QRIO: a small entertainment humanoid (SONY). Automous car roboethics Autonomous (self-driving, driverless) cars are on the way. Proponents of autonomous cars and other vehicles argue that within two or three decades autonomously driving cars will be so accurate that will dominate in number human-driving cars.25,26 The speciics of self-driving vary from manufacturer to manufacturer, but at the basic level cars use a set of cameras, lasers and sensors located around the vehicle for detecting obstacles, and through GPS (global positioning systems) help them to move at a preset route. Currently there are cars on the road that perform several driving tasks autonomously (without the help of the human driver). Examples are: lane assist system to keep the car on lane, cruise control system that speeds-up or slows down according to the speed of the car in front, and automatic emergency braking for emergency stop to prevent collisions with pedestrians. SAE (Society of Automotive Engineers) International (www.sae.org/ autodrive) has developed and released a new standard (J3016) for the “Taxonomy and deinitions of terms related to on-road motor vehicle automated driving systems”. War/military roboethics Military robots, especially lethal autonomous robotic weapons, lie at the center of roboethics. Supporters of the use of war robots argue that these robots have substantial advantages which include the saving of the lives of soldiers, and the conduct of war more ethically and effectively than human soldiers who, under the inluence of emotions, anger, fatigue, vengeance, etc., may over-react and overstep the laws of war. The opponents of the use of autonomous killer robots argue that weapon autonomy itself is the problem and not mere control of autonomous weapons could ever be satisfactory. Their central belief is that autonomous lethal robots must be entirely prohibited. The ethics of war attempts to resolve what is right or wrong, both for the individual and the states or countries contributing to debates on public policy, and ultimately leading to the establishment of codes of war.26,27 The three dominating traditions (doctrines) in the ‘‘ethics of war and peace are):28 a. Realism (war is an inevitable process taking place in the anarchical world system). b. Paciism or anti-warism (rejects war in favor of peace) c. Just war (just war theory speciies the conditions for judging if it is just to go to war, and conditions for how the war should be conducted). The ethical and legal rules of conducting wars using robotic weapons, in addition to conventional weapons, includes at minimum all the rules of just war, but the use of semiautonomous/autonomous robots add new rules for iring decision, discrimination of lawful from unlawful targets, responsibility, and proportionality.27,28 232 Cyborg ethics Cyborg technology aims to design and study neuromotor prostheses in order to store and reinstate lost function with replacement that is different as little as possible from the real thing (a lost arm or hand, lost vision etc.).29 The word Cyborg stands for cybernetic organism, a term coined by Manfred Clynes and Nathan Kline.30 A cyborg is any living being that has both organic and mechanical/electrical parts that either restore or enhance the organism’s functioning. People with the most common technological implants such as prosthetic limbs, pacemakers, and cochlear/bionic ear implants, or people who receive implant organs developed from artiicially cultured stem cells can be consired to belong to this category. The irst real cyborg was a ‘lab rat’ at Rockland State Hospital in 1950 (New York). The principal advantages of mixing organs with mechanical parts are for the human health. For example: a. People with replaced parts of their body (hips, elbows, knees, wrists, arteries, etc.) can now be classiied as Cyborg. b. Brain implants based on neuromorphic model of the brain and the nervous system help reverse the most devastating symptoms of Parkinson disease. Disadvantages of Cyborg include: a. Cyborgs do not heal body damage normally, but, instead, body parts are replaced. Replacing broken limbs and damaged armor plating can be expensive and time consuming. b. Cyborgs can think the surrounding world in multiple dimensions, whereas human beings are more restricted in that sense. A comprehensive discussion of Cyborgs is given.31 Automation technology ethics: Automation technology ethics is the part of applied ethics and technology ethics (technoethics) which studies the application of ethics to processes and systems automated in one or the other degree.36,32 Today, automation is achieved using digital computers technology, digital feedback control technology, information technology, and modern communication technology. Therefore the ethical issues of automation naturally overlap considerably with the ethical issues rising in all of these areas, and can be studied in a uniied way. As noted33 many people feel that using a computer to do something which is illegal or unethical is somehow not as “wrong” as other “real” criminal or unethical acts. A crucial fact regarding the application of ethics and ethical standards in information-based practice is that many professionals in this area do not belong to professional organizations, and many others do not belong to any professional organization. Three fundamental questions about information and automation ethics addressed are:34-36 a. What constitute substantive ethical issues and how can we learn or know about ethics related to automation? b. Do we need better ethics for automation systems? What is this better ethics? c. Does anticipatory ethics that studies ethical issues at the R&D and introduction stage of a technology, via anticipation of possible future equipment, applications, and social implications, help to determine and develop a better automation ethics? Three principal information and service requirements in automation systems are the following, and their achievement depends on ethical performance of engineers and professionals: Citation: Tzafestas SG. Ethics in robotics and automation: a general view. Int Rob Auto J. 2018;4(3):229‒234. DOI: 10.15406/iratj.2018.04.00127 Copyright: ©2018 Tzafestas Ethics in robotics and automation: a general view Accuracy: Information must be as more accurate as possible such that the conclusions or decisions based on it are correct. Today the information which is viable and being accessed is suficiently accurate. Accessibility: Information must be accessible. Accessibility involves the right of accessing the required information, as well as true payments of charges to access the information. Quality of service: In contrast to goods, services are intangible and heterogeneous. Production and consumption of service are inseparable. Quality of service (QoS) is deined and evaluated by the client, and is not evaluated only on the basis of outcomes but on processing delivery. The key requirements for QoS are:37 a. Reliability (promised service should be performed dependably and accurately). b. Competence (the company has the skill and knowledge to carry out the service). c. Responsiveness (readiness and willingness to provide the service). d. Access (service personnel easily approachable by customers). e. Courtesy (politeness and friendliness of service personnel). Other areas of ethical concern in R&A are: I. II. Criminal behavior. Ownership and copyright. III. Privacy and anonymity. IV. Autonomy. V. VI. Identity. Professional conduct. Automation can have positive and negative impacts for the people, the organizations, and the society in general.38 Basic questions related to R&A social impact are the following: a. How might R&A affect the everyday life of human society members? 233 the employment and society is provided.39 Ethics is overlapping with law but goes beyond it. Laws provide a minimum set of standards for obtaining a desired human behavior. Ethics often provides standards that exceed the legal minimum. Therefore, that which is legal is not always ethical. For good human behavior and development both law and ethics should be respected. Speciically, ethics and laws are different in the manner that ethics tells what a person should do and laws specify what a person must do. The law is universally accepted, and ethics is ideal human conduct agreed upon by most of the people. The best results are obtained if the law and ethics go side by side so as to guide to actions that are both legal and ethical.40,41 Conclusion This paper has provided a short conceptual review of the ethical aspects and social implications of R&A. The material presented starts with the fundamental phisophical questions about R&A ethics which have been addressed in the literature and still provide motivation for further research. Then, the core of the paper is presented which includes: a. the review of R&A ethics, b. an outline of the major branches of roboethics (medical robot, assistive robot, social robot, autonomous cars, war/military robot, cyborg ethics), and c. a discussion of automation technology ethics and social implications. Extensive coverage of the concepts, and topics reviewed in the paper is provided in the references cited. A global conclusion is that there is still a strong need to develop more practical, and easy to understand and apply, ethical rules and codes for the designers, professionals, and users of R&A products. Acknowledgements My Institute’s (National Technical University of Athens) representative needs not to be fully aware of this submission. Conlict of interest The author declares there is no conlict of interest. b. Could vulnerable people be particularly affected by R&A? References c. Could events occurring in the virtual world of R&A have negative impact on the real world? 1. Wallach W, Allen C. Moral machines: Teaching robots right from wrong. Oxford, UK: Oxford University Press; 2009. d. Does R&A seek informed consent where necessary? From a technical point of view, robotic automation implies a range of technical advantages and disadvantages, namely: Advantages: Reliability, Sensitivity, Endurance, Motion velocity, Mechanical power, Work accuracy. Disadvantages: Human isolation feeling, Telepresence and virtual reality. The interaction between automated systems and robots with people brings about new legal considerations in respect to safety and health regulations, law compliance, and assignment/apportioning of risk and liability. Those using robotic production lines that rely heavily on multiple technologies should ensure that they have contractual arrangements agreed with each machine or technology supplier.
