    Executive Summary World Robotics 2019 Service Robots 11 Executive Summary World Robotics 2019 Service Robots Service robotics encompasses a broad field of applications, most of which having unique designs and different degrees of automation – from full tele-operation to fully autonomous operation. Hence, the industry is more diverse than the industrial robot industry (which is extensively treated in the companion publication World Robotics – Industrial Robots 2019). IFR Statistical Department is currently aware of more than 750 companies producing service robots or doing commercial research for marketable products. A full list is included in chapter 4 of World Robotics Service Robots 2019. IFR Statistical Department is continuously seeking for new service robot producers, so please contact [email protected] if you represent such a company and would like to participate in the annual survey conducted in the first quarter of each year. Participants receive the survey results free of charge. Sales of professional service robots on the rise The total number of professional service robots sold in 2018 rose by 61% to more than 271,000 units, up from roughly 168,000 in 2017. The sales value increased by 32% to USD 9.2 billion. Autonomous guided vehicles (AGVs) represent the largest fraction in the professional service robot market (41% of all units sold). They are established in non-manufacturing environments, mainly logistics, and have lots of potential in manufacturing. The second largest category (39% of all units sold), inspection and maintenance robots, covers a wide range of robots from rather low-priced standard units to expensive custom solutions. Service robots for defense applications accounted for 5% of the total number of service robots for professional use sold in 2018.

  • What Can We Learn from the Long-Term Users of a Social Robot?
    This is the post print version of the article Kertész, Turunen: What Can We Learn from the Long-Term Users of a Social Robot? In: Social Robotics 9th International Conference, ICSR 2017, Tsukuba, Japan, November 22-24, 2017, Proceedings, 657-665. The final publication is available at Springer via https://doi.org/10.1007/978-3-319-70022-9_65 What Can We Learn from the Long-Term Users of a Social Robot? Csaba Kertész1 and Markku Turunen1 1 Tampere Unit for Computer-Human Interaction, University of Tampere, Tampere, Finland [email protected], [email protected] Abstract. Despite the recent technological advances, long-term experiments with robots have challenges to keep the users interested after the initial excitement disappears. This paper explores the user expectations by analyzing the long-term owners of Sony AIBO who have been using these robots for years (heavy users). 78 participants filled an on-line questionnaire and their answers were inspected to discover the key needs of this user group. Quantitative and textual methods confirmed that the most-wanted skills were the interaction with humans and the autonomous operation. The integration with the AI agents and Internet services was important, but the long-term memory and learning capabilities were not that relevant for the participants as expected. The diverse preferences between robot skills led to the creation of a prioritized recommendation list to complement the design guidelines for social robots in the literature. Keywords: questionnaire, user expectations, heavy users, Sony AIBO. 1 Introduction Nowadays more and more social robots are introduced onto the market and the user expectations must be understood for the researchers to execute successful long-term experiments and for the companies to create sustainable business plans.

  • How Humanoid Robots Influence Service Experiences and Food Consumption
    Marketing Science Institute Working Paper Series 2017 Report No. 17-125 Service Robots Rising: How Humanoid Robots Influence Service Experiences and Food Consumption Martin Mende, Maura L. Scott, Jenny van Doorn, Ilana Shanks, and Dhruv Grewal “Service Robots Rising: How Humanoid Robots Influence Service Experiences and Food Consumption” © 2017 Martin Mende, Maura L. Scott, Jenny van Doorn, Ilana Shanks, and Dhruv Grewal; Report Summary © 2017 Marketing Science Institute MSI working papers are distributed for the benefit of MSI corporate and academic members means, electronic or mechanical, without written permission. Report Summary Interactions between consumers and humanoid service robots (i.e., robots with a human-like morphology such as a face, arms, and legs) soon will be part of routine marketplace experiences, and represent a primary arena for innovation in services and shopper marketing. At the same time, it is not clear whether humanoid robots, relative to human employees, trigger positive or negative consequences for consumers and companies. Although creating robots that appear as much like humans as possible is the “holy grail” in robotics, there is a risk that consumers will respond negatively to highly human-like robots, due to the feelings of discomfort that such robots can evoke. Here, Martin Mende, Maura Scott, Jenny van Doorn, Ilana Shanks, and Dhruv Grewal investigate whether humanoid service robots (HSRs) trigger discomfort and what the consequences might be for customers’ service experiences. They focus on the effects of HSRs in a food consumption context. Six experimental studies, conducted in the context of restaurant services, reveal that consumers report lower assessments of the server when their food is served by a humanoid service robot than by a human server, but their desire for food and their actual food consumption increases.

  • Development of a Series Elastic Actuator and a Distributed Computational Platform for Robotics
    Development of a Series Elastic Actuator and a Distributed Computational Platform for Robotics Gonçalo Patrício Luís Thesis to obtain the Master of Science Degree in Mechanical Engineering Supervisor: Prof. Jorge Manuel Mateus Martins Examination Committee Chairperson: Prof. João Rogério Caldas Pinto Supervisor: Prof. Jorge Manuel Mateus Martins Member of the Committee: Prof. Carlos Baptista Cardeira November 2015 i ii To my Parents iii iv Acknowledgments I would like to thank Professor Jorge Martins for believing in my ideas on building a new computational platform from scratch in detriment of using the old platform. The first task he gave me was to play arround with the old platform until I felt confortable with it, not all teachers believe in loosing time on learning things that are supposed to work and should only be used instead of studied. In the end the freedom he gave me turned into finding gross mistakes in the old platform and ultimately building a new, more capable one. I would like to thank Professor Carlos Cardeira for clearing some questions I had about electronics regarding the circuit board for voltage conversion. I would also like to thank Professor Paulo Oliveira and Professor Alexandra Moutinho for showing me the power and beauty of control systems engineering in the lecture I had with them on that topic. Their practical and clear explanations ultimately made me choose Systems as my Masters area, a choice I couldn’t be happier about. I am also deeply grateful to all the other teachers on the systems department and Eng. Camilo for creating and maintaining a friendly environment during classes and at the laboratory.

  • Development of a Robot Bear: Bringing the Strength and Robustness of a Bear’S Biomimetic Features to a Robot
    Proceedings of the 2008 IEEE International Conference on Robotics and Biomimetics Bangkok, Thailand, February 21 - 26, 2009 HyKim – Development of a robot bear: Bringing the strength and robustness of a bear’s biomimetic features to a robot. Peter Turner Michael Dickinson School of Electrical Engineering School of Design, Communication and Computer Science and Information. Technology University of Newcastle University of Newcastle Callaghan 2308, NSW, Australia Callaghan 2308, NSW, Australia [email protected] [email protected] Abstract – There are many commercially available robots that display biomimetic influences. Sony’s Aibo and DasaRobot’s Genibo are two examples where robot dog designs have drawn from nature. Aldebaran’s Nao and Hanson Robotics’ Zeno are examples of humanoids robots that have drawn influences from the human body. This paper presents the design of an autonomous 21 Degree of Freedom (DOF) robot bear, named HyKim and discusses the relevant biomimetic influences. After discussing the motivation for creating a robot bear, the biomimetic principles that were applied to the mechanical design, to ensure the resulting robot was ‘bear-like’, are presented. The design of the computer and electronic architecture was based on four essential design criteria – open architecture, performance, modularity and reliability. How these criteria were met is then presented, followed by a discussion on future research projects that will be based on or include HyKim. Finally a conclusion summarising the design is presented.
