In October 2019 Springer VS published the “Handbuch Maschinenethik” (“Handbook Machine Ethics”) with German and English contributions. Editor is Oliver Bendel (Zurich, Switzerland). One of the articles was written by Bertram F. Malle (Brown University, Rhode Island) and Matthias Scheutz (Tufts University, Massachusetts). From the abstract: “We describe a theoretical framework and recent research on one key aspect of robot ethics: the development and implementation of a robot’s moral competence. As autonomous machines take on increasingly social roles in human communities, these machines need to have some level of moral competence to ensure safety, acceptance, and justified trust. We review the extensive and complex elements of human moral competence and ask how analogous competences could be implemented in a robot. We propose that moral competence consists of five elements, two constituents (moral norms and moral vocabulary) and three activities (moral judgment, moral action, and moral communication). A robot’s computational representations of social and moral norms is a prerequisite for all three moral activities. However, merely programming in advance the vast network of human norms is impossible, so new computational learning algorithms are needed that allow robots to acquire and update the context-specific and graded norms relevant to their domain of deployment. Moral vocabulary is needed primarily for moral communication, which expresses moral judgments of others’ violations and explains one’s own moral violations – to justify them, apologize, or declare intentions to do better. Current robots have at best rudimentary moral competence, but with improved learning and reasoning they may begin to show the kinds of capacities that humans will expect of future social robots.” (Abstract “Handbuch Maschinenethik”). The book is available via www.springer.com.
How to Improve Robot Hugs
Hugs are very important to many of us. We are embraced by familiar and strange people. When we hug ourselves, it does not have the same effect. And when a robot hugs us, it has no effect at all – or we don’t feel comfortable. But you can change that a bit. Alexis E. Block and Katherine J. Kuchenbecker from the Max Planck Institute for Intelligent Systems have published a paper on a research project in this field. The purpose of the project was to evaluate human responses to different robot physical characteristics and hugging behaviors. “Analysis of the results showed that people significantly prefer soft, warm hugs over hard, cold hugs. Furthermore, users prefer hugs that physically squeeze them and release immediately when they are ready for the hug to end. Taking part in the experiment also significantly increased positive user opinions of robots and robot use.” (Abstract) The paper “Softness, Warmth, and Responsiveness Improve Robot Hugs” was published in the International Journal of Social Robotics in January 2019 (First Online: 25 October 2018). It is available via link.springer.com/article/10.1007/s12369-018-0495-2.
A Handbook on Machine Ethics
After three years, an ambitious project has come to its preliminary end: The “Handbuch Maschinenethik” (“Handbook Machine Ethics”) (edited by Oliver Bendel) was published by Springer in mid-October 2019. It brings together contributions from leading experts in the fields of machine ethics, robot ethics, technology ethics, technology philosophy and robot law. At the moment it can be downloaded here: link.springer.com/book/10.1007/978-3-658-17483-5 … It has become an extensive, a remarkable, a unique book. In a way, it is a counterpart to American research, which dominates the discipline: Most authors come from Europe and Asia. The editor, who has been involved with information ethics, robotics and machine ethics for 20 years and has been researching machine ethics intensively for eight years, is full of hope that the book will find its place in the standard literature on machine ethics, such as “Moral Machines” (2009) by Wendell Wallach and Colin Allen and “Machine Ethics” (2011) by Michael and Susan Leigh Anderson, and “Programming Machine Ethics” (2016) by Luís Moniz Pereira (with Ari Saptawijaya) and “Grundfragen der Maschinenethik” (2018) by Catrin Misselhorn – both have contributed significantly to the “Handbuch Maschinenethik”. Over the next few days, the book with its 23 chapters and 469 pages will be made available for sale on the Springer website and also in print.
An Autonomous Ship at Sea
The Mayflower Autonomous Ship (MAS) could be the first vessel to cross the Atlantic that is able to navigate around obstacles and hazards by itself. It will depart from Plymouth, UK on the fourth centenary of the original Mayflower voyage, on 6 September 2020, and will reach Plymouth, USA after an ecxiting tour, dedicated to science. “The project was put together by marine research and exploration company ProMare in an effort to expand the scope of marine research. The boat will carry three research pods equipped with scientific instruments to measure various phenomena such as ocean plastics, mammal behaviour or sea level changes.” (ZDnet, 16 October 2019) According to ZDnet, IBM has now joined the initiative to supply technical support for all navigation operations. It is important that the futuristic ship is not only careful with things, but also with animals. In this context, insights of animal-machine interaction and machine ethics might be useful. Ultimately, the excursion will help the marine mammals by obtaining data on their behaviour.
The Sleep Robot by your Side
A Guardian journalist just tested the Somnox Sleep Robot that aims to banish insomnia, aiding natural rest and reducing stress. According to him, it could be revolutionary in the field because many overnight devices merely track sleep rather than promoting it. Somnox describes its robot as a “sleep companion”. “The kidney-shaped, possibly sentient cushion breathes softly in and out, and plays calming noises. The idea is that users hold it close to them in bed, building up an emotional bond over time. Every night, you breathe together in time until you fall sleep, perchance to dream of electric sheep.” (Guardian, 15 October 2019) The journalist was not satisfied with the device at all. But an advanced sleeping robot could be of help to certain groups. Maybe some people are mainly interested in the feeling of having something next to them. One should give the sleep robot a second chance.
A Markup Language for Moral Machines
A markup language is a machine-readable language for structuring and formatting texts and other data. The best known is the Hypertext Markup Language (HTML). Other well-known artifacts are SSML (for the adaptation of synthetic voices) and AIML (for artificial intelligence applications). We use markup languages to describe properties, affiliations and forms of representation of sections of a text or set of data. This is usually done by marking them with tags. In addition to tags, attributes and values can also be important. A student paper at the School of Business FHNW will describe and compare known markup languages. It will examine whether there is room for further artifacts of this kind. A markup language, which would be suitable for the morality in the written and spoken as well as the morally adequate display of pictures, videos and animations and the playing of sounds, could be called MOML (Morality Markup Language). Is such a language possible and helpful? Can it be used for moral machines? The paper will also deal with this. The supervisor of the project, which will last until the end of the year, is Prof. Dr. Oliver Bendel. Since 2012, he and his teams have created formulas and annotated decision trees for moral machines and a number of moral machines themselves, such as GOODBOT, LIEBOT, BESTBOT, and LADYBIRD.
Towards Robots with Artificial Skin
“Sensitive synthetic skin enables robots to sense their own bodies and surroundings – a crucial capability if they are to be in close contact with people. Inspired by human skin, a team at the Technical University of Munich (TUM) has developed a system combining artificial skin with control algorithms and used it to create the first autonomous humanoid robot with full-body artificial skin.” (Press Release TUM, 10 October 2019) The robot skin consists of hexagonal cells which are about the size of a two-euro coin. Each of them is equipped with a microprocessor and sensors to detect contact, acceleration, proximity, and temperature. “Such artificial skin enables robots to perceive their surroundings in much greater detail and with more sensitivity. This not only helps them to move safely. It also makes them safer when operating near people and gives them the ability to anticipate and actively avoid accidents.” (Press Release TUM, 10 October 2019) The artificial skin could become important for service robots of all kinds, but also for certain industrial robots (Photo: Department of Electrical and Computer Engineering, Astrid Eckert).
Interpretable AI for Well-Being
The papers of the AAAI 2019 Spring Symposium “Interpretable AI for Well-Being: Understanding Cognitive Bias and Social Embeddedness symposium” were published in October 2019. The participants had met at Stanford University at the end of March 2019 to present and discuss their findings. Session 5 (“Social Embeddedness”) includes the following publications: “Are Robot Tax, Basic Income or Basic Property Solutions to the Social Problems of Automation?” (Oliver Bendel), “Context-based Network Analysis of Structured Knowledge for Data Utilization” (Teruaki Hayashi, Yukio Ohsawa), “Extended Mind, Embedded AI, and ‘the Barrier of Meaning'” (Sadeq Rahimi), “Concept of Future Prototyping Methodology to Enhance Value Creation within Future Contexts” (Miwa Nishinaka, Yusuke Kishita, Hisashi Masuda, Kunio Shirahada), and “Maintaining Knowledge Distribution System’s Sustainability Using Common Value Auctions” (Anas Al-Tirawi, Robert G. Reynolds). The papers can be downloaded via ceur-ws.org/Vol-2448/.
Honey, I shrunk the AI
Some months ago, researchers at the University of Massachusetts showed the climate toll of machine learning, especially deep learning. Training Google’s BERT, with its 340 million data parameters, emitted nearly as much carbon as a round-trip flight between the East and West coasts. According to Technology Review, the trend could also accelerate the concentration of AI research into the hands of a few big tech companies. “Under-resourced labs in academia or countries with fewer resources simply don’t have the means to use or develop such computationally expensive models.” (Technology Review, 4 October 2019) In response, some researchers are focused on shrinking the size of existing models without losing their capabilities. The magazine wrote enthusiastically: “Honey, I shrunk the AI” (Technology Review, 4 October 2019) There are advantages not only with regard to the environment and to the access to state-of-the-art AI. According to Technology Review, tiny models will help bring the latest AI advancements to consumer devices. “They avoid the need to send consumer data to the cloud, which improves both speed and privacy. For natural-language models specifically, more powerful text prediction and language generation could improve myriad applications like autocomplete on your phone and voice assistants like Alexa and Google Assistant.” (Technology Review, 4 October 2019)
The Future of Autonomous Driving
Driving in cities is a very complex matter. There are several reasons for this: You have to judge hundreds of objects and events at all times. You have to communicate with people. And you should be able to change decisions spontaneously, for example because you remember that you have to buy something. That’s a bad prospect for an autonomous car. Of course it can do some tricks: It can drive very slowly. It can use virtual tracks or special lanes and signals and sounds. A bus or shuttle is able to use such tricks. But hardly a car. Autonomous individual transport in cities will only be possible if the cities are redesigned. This has been done a few decades ago. And it wasn’t a good idea at all. So don’t let autonomous cars drive in the cities, but let them drive on the highways. Should autonomous cars make moral decisions about the lives and deaths of pedestrians and cyclists? They should better not. Moral machines are a valuable innovation in certain contexts. But not in the traffic of cities. Pedestrians and cyclists rarely get onto the highway. There are many reasons why we should allow autonomous cars only there.
