With Hugvie and Somnox Sleep Robot, researchers and companies has made it clear that it is possible to build simple, soft social robots that have a certain utility and impact. This raises hopes for social robotics, which is currently showing some progress, but is still developing slowly. Materials such as rubber and plastic can be used to make simple, soft social robots. These materials can be combined with existing devices such as smartphones and tablets on which you run certain applications, or with simple sensors and electronic components. The project or thesis, announced by Oliver Bendel in August 2020 at the School of Business FHNW, will first do research on the basics of simple, soft social robots. The work of Hiroshi Ishiguro and Alexis Block (with Katherine J. Kuchenbecker) will be included. Then, examples of implementation forms are mentioned and sketched. Their purpose and benefits are presented, as well as possible areas of application. One example is to be implemented, whereby speech abilities and sounds can be an option as well as vibration and electrical impulses. The reference to applications in the household, in public space or in the commercial sector should be established. The project will start in February 2021.
Social robots and service robots usually have a defined locomotor system, a defined appearance and defined mimic and gestural abilities. This leads, on the one hand, to a certain familiarization effect. On the other hand, the actions of the robots are thus limited, for example in the household or in a shopping mall. Robot enhancement is used to extend and improve social robots and service robots. It changes their appearance and expands their scope. It is possible to apply attachments to the hardware, extend limbs and exchange components. One can pull skin made of silicone over the face or head, making the robots look humanoid. One can also change the software and connect the robot to AI systems – this is already done many times. The project or thesis, announced by Oliver Bendel in August 2020 at the School of Business FHNW, should first present the principles and functional possibilities of robot enhancement. Second, concrete examples should be given and described. One of these examples, e.g., the skin made of silicone, has to be implemented. Robots like Pepper or Atlas would be completely changed by such a skin. They could look uncanny, but also appealing. The project will start in September 2020.
In the first part of the HUGGIE project initiated by Oliver Bendel, two students of the School of Business FHNW conducted an online survey with almost 300 participants. In the management summary of their bachelor thesis Ümmühan Korucu and Leonie Stocker (formerly Leonie Brogle) write: “The results of the survey indicated that people have a positive attitude towards robots in general as robots are perceived as interesting and useful rather than unnecessary and disturbing. However, only a minority of the participants stated that they would accept a hug from a robot. A possible reason for this could be that for the majority of participants, a hug is an act of intimacy with a deeper meaning attached to it which is only being shared with selected persons. For a robot to be perceived as an attractive hugging partner, a human-like design including a face, eyes, a friendly look as well as the ability to communicate verbally and non-verbally is desired. However, an appearance being too realistic has a deterrent effect. Furthermore, an in-depth analysis of the data in relation to age and gender of the participants resulted in the discovery of interesting facts and differences. Overall, the findings contribute to a clearer picture about the appearance and the features Huggie should have in order to be accepted as a hugging counterpart.” The bachelor thesis will be publicly available in autumn 2020. There will also be a paper with the results next year.
At the end of June 2020, DIE WELT conducted an interview with Prof. Dr. Oliver Bendel about sex robots and love dolls. It was especially about their natural language skills. Particularly owners and users who want to have a relationship are interested in conversations of all kinds, about God and the world and in the sense of “dirty talk”. Companies like Realbotix go very far in this respect. Harmony for example can talk to her partners for hours in a quite convincing way. The engineers experiment with GPT-2, but also with other language models. Kino Coursey, AI boss of Realbotix, deals with this topic in his article “Speaking with Harmony” for the book “Maschinenliebe” (“Machine Love”) which will be released in October. The interview with Oliver Bendel was published on 11 July 2020 in the printed edition of DIE WELT, under the title “Intelligente Sexroboter sind begehrte Gesprächspartner” (already published the day before in the electronic edition, under the title “Was Sexpuppen können” …). In addition, an English version – “Intelligent sex robots are sought-after dialogue partners” – is available.
The COVID-19 pandemic has given a boost to service robotics. Transport, safety and care robots are in demand, as are cleaning and disinfection robots. Service robots measure the temperature of passengers at airports and railway stations. Now they can also perform COVID-19 tests. “Robotics researchers from the University of Southern Denmark have developed the world’s first fully automatic robot capable of carrying out throat swabs for Covid-19, so that healthcare professionals are not exposed to the risk of infection. The prototype has successfully performed throat swabs on several people. The scientists behind are cheering: The technology works!” (Website SDU, 27 May 2020) A robot arm as known from the industry was used. The end piece comes from the 3D printer. This is another example from the health sector that shows how industrial robots – such as cobots – can become service robots.

In May 2020 the media was interested in a video by Rocos showing a robot from Boston Dynamics trying to be a shepherd dog. You could see the artificial quadruped running towards a flock of sheep. “Now, it’s clear that the video is mostly a fun teaser rather than a serious claim by Rocos (or Boston Dynamics) that robots will soon be replacing sheepdogs.” (The Verge, 22 May 2020) According to the magazine, it does invite a tantalizing question: if that did happen, “how well would the robots fare” (The Verge, 22 May 2020)? “Terrible”, is the straight answer of sheep farmer and author James Rebanks. “The robot might be an amazing tool for lots of things but it is worthless and unwanted as a sheepdog …” (The Verge, 22 May 2020) However, the profession of shepherd is not everywhere in the world the dream of all boys and girls, and shepherd dogs do not fall from the sky. It is also not clear whether there is a big difference for the sheep and how positively or negatively they react to the machine. It is just as unclear whether lambs that have never met real dogs would be comfortable with it. This would have to be researched in animal psychology and social robotics and in disciplines such as animal-machine interaction, which are still in their infancy. Only then would one know whether the shepherd interviewed by the magazine is right.
DIH-HERO is a project in the healthcare sector supported by the European Union since January 2019. According to the website, the mission is to create a sustaining network that connects players in the healthcare sector and to support small and medium sized enterprises. “Currently, Europe and countries all over the world are facing a global pandemic. Together with its extensive Robotics in Healthcare European network DIH-HERO decided to support the fight against COVID-19 by providing €1,000,000 for robotic technologies that can be deployed timely, in order to support healthcare professionals and save lives by satisfying a current clinical demand or need.” (Website DIH-HERO) F&P Robotics based in Switzerland is one of the winners of the announcement. Lio – one of the company’s flagships – will now learn new tasks in the field of disinfection (door traps, lift buttons). The normal use of the care robot was last described in a paper by Oliver Bendel (School of Business FHNW), Alina Gasser and Joel Siebenmann (F&P Robotics) that was accepted at the AAAI 2020 Spring Symposia. Because of COVID-19 the lecture was postponed to late autumn.
Animal-machine interaction (AMI) and animal-computer interaction (ACI) are increasingly important research areas. For years, semi-autonomous and autonomous machines have been multiplying all over the world, not only in factories, but also in outdoor areas and in households. Robots in agriculture and service robots, some with artificial intelligence, encounter wild animals, farm animals and pets. Jackie Snow, who writes for New York Times, National Geographic, and Wall Street Journal, talked to several people on the subject last year. In an article for Fast Company, she quoted the ethicists Oliver Bendel (“Handbuch Maschinenethik”) and Peter Singer (“Animal Liberation”). Clara Mancini (“Animal-computer interaction: A manifesto”) also expressed her point of view. The article with the title “AI’s next ethical challenge: how to treat animals” can be accessed here. Today, research is also devoted to social robots. One question is how animals react to them. Human-computer interaction (HCI) experts from Yale University recently looked into this topic. Another question is whether we can create social robots specifically for animals. The first beginnings were made with toys and automatic feeders for pets. Could a social robot replace a contact person for weeks on end? What features should it have? In this context, we must pay attention to animal welfare from the outset. Some animals will love the new freedom, others will hate it.
In 2016, the roboticist Maja Matarić founded Embodied, together with Paolo Pirjanian, former CTO of iRobot. In April 2020, the company started accepting preorders for Moxie, its first social robot. “Whereas other companion robots like the household assistant Jibo or Paro the robotic seal are designed for adults or the elderly, Moxie is built to foster social, cognitive, and emotional development in children. These are skills that are typically imparted to kids by their parents, teachers, and other adults, but Pirjanian noticed that many families want some extra help.” (Wired, 30 April 2020) According to the company, weekly themes and missions with Moxie explore human experiences, ideas, and life skills like kindness, empathy, and respect. Showing emotions is an important skill of social robots. SoftBank has created a model example with Pepper. Cozmo by Anki – currently not available – can also show emotions, even a multitude. And both Pepper and Cozmo create emotions in the user. Cozmo and Moxie have something in common, namely an effort of Pixar: “Taking a page from Anki’s Cozmo playbook, the company has enlisted the help of employees from Pixar and Jim Henson to flesh out the real-world robotic character. At first glance, the results are plenty impressive.” (TechCrunch, 4 May 2020)
Embraces by robots are possible if they have two arms, such as Pepper and P-Care, restricted also with one arm. However, the hugs and touches feel different to those made by humans. When one uses warmth and softness, like in the HuggieBot project, the effect improves, but is still not the same. In hugs it is important that another person hugs us (hugging ourselves is totally different), and that this person is in a certain relationship to us. He or she may be strange to us, but there must be trust or desire. Whether this is the case with a robot must be assessed on a case-by-case basis. A multi-stage HUGGIE project is currently underway at the School of Business FHNW under the supervision of Prof. Dr. Oliver Bendel. Ümmühan Korucu and Leonie Brogle started with an online survey that targets the entire German-speaking world. The aim is to gain insights into how people of all ages and sexes judge a hug by a robot. In crises and catastrophes involving prolonged isolation, such as the COVID 19 pandemic, proxy hugs of this kind could well play a role. Prisons and longer journeys through space are also possible fields of applications. Click here for the survey (only in German): ww3.unipark.de/uc/HUGGIE/ …
