Seit 1997 finden jährlich Weltmeisterschaften im Roboterfußball statt. Dabei wird in verschiedenen Ligen teils mit echten, teils mit simulierten Robotern Fußball gespielt. In der small size league spielen fünf gegen fünf Roboter auf einem 5x4,5 m großen Feld. Die Steuerung der Roboter wird von einem externen Rechner übernommen, der seine Information von einer über dem Feld angebrachten Kamera erhält. In der middle size league spielen vier gegen vier Roboter auf einem 8x12 m großen Feld. Hier müssen im Unterschied zur small size league die Roboter vollständig autonom sein, d.h., alle Sensoren und auch die Entscheidungslogik muss auf dem Roboter selbst untergebracht sein. Dasselbe gilt für die four legged robot league, bei der jeweils vier Sony Aibo Roboter gegeneinander antreten (Abbildung 1.11-1), sowie für die Königsklasse, der humanoid league, bei der jeweils drei zweibeinige Roboter gegeneinander spielen. Daneben existieren zwei Simulationsligen: die seit 1997 existierende 2D simulation league, bei der elf gegen elf gespielt wird und die seit 2005 im Programm befindliche 3D simulation league, bei der im Gegensatz zur 2D league tatsächlich existierende zweibeinige Nao-Roboter simuliert werden. In dieser Liga hat sich erstmals eine Mannschaft der Hochschule Offenburg für die Weltmeisterschaft 2009 qualifiziert. Neben Fußballrobotern gibt es auch Ligen für Hausroboter (RoboCup@Home) und Rettungsroboter (RoboCup Rescue). Inzwischen ist die RoboCup WM mit der zugehörigen Konferenz zum größten Robotik-Event weltweit avanciert.
Seit 1997 finden jährlich Weltmeisterschaften im Roboterfußball statt. Das Ziel ist es dabei, bis 2050 eine Mannschaft aus Robotern zu stellen, die gegen den menschlichen Fußballweltmeister gewinnt. Dazu müssen die Roboter in der Lage sein, das Verhalten ihrer menschlichen Gegner einzuschätzen und ihre Entscheidungen vorauszuahnen. Während die gängigen Verfahren zur Entscheidungsfindung in unsicheren Umgebungen in der Regel auf rationalen Entscheidungen nach der Entscheidungstheorie basieren, zeigt sich, dass menschliches Entscheiden teilweise nicht dieser Rationalität folgt. Daniel Kahneman und Amos Tversky zeigten das in vielen Studien und entwickelten daraus die bekannte Prospect Theory für die Kahneman 2002 den Wirtschaftsnobelpreis erhielt. In diesem Artikel wird beschrieben, wie Extended Behavior Networks (EBNs) auf einfache Weise erweitert werden können, um menschliches Entscheidungsverhalten auch in Situationen reproduzieren zu können, die von der rationalen Entscheidungstheorie abweichen.
Die spektroskopische Beobachtung von postmortalen Hautveränderungen und insbesondere von Totenflecken ermöglicht potenziell eine genauere Bestimmung des Todeszeitpunkts oder der Todesursache (z. B. im Fall von CO-Vergiftungen). Für die grundlegende Charakterisierung dieser Veränderungen sind Langzeitbeobachtungen von Stunden oder gar Tagen wünschenswert.
In this paper we propose a motion framework forbipedal robots that decouples motion definitions from stabilizingthe robot. This simplifies motion definitions yet allows dynamicmotion adaptations. Two applications, walking and stopping onone leg, demonstrate the power of the framework. We show thatour framework is able to perform walking and stopping on one legeven under extreme conditions and improves walking benchmarkssignificantly in the RoboCup 3D soccer simulation domain.
Autonomous humanoid robots need high torque actuators to be able to walk and run. One problem in this context is the heat generated. In this paper we propose to use water evaporation to improve cooling of the motors. Simulations based on thermodynamic calculations as well as measurements on real actuators show that, under the assumption of the load of a soccer game, cooling can be considerably improved with relatively small amounts of water.
In this article, we present a taxonomy in Robot-Assisted Training; a growing body of research in Human–Robot Interaction which focuses on how robotic agents and devices can be used to enhance user’s performance during a cognitive or physical training task. Robot-Assisted Training systems have been successfully deployed to enhance the effects of a training session in various contexts, i.e., rehabilitation systems, educational environments, vocational settings, etc. The proposed taxonomy suggests a set of categories and parameters that can be used to characterize such systems, considering the current research trends and needs for the design, development and evaluation of Robot-Assisted Training systems. To this end, we review recent works and applications in Robot-Assisted Training systems, as well as related taxonomies in Human–Robot Interaction. The goal is to identify and discuss open challenges, highlighting the different aspects of a Robot-Assisted Training system, considering both robot perception and behavior control.
Social robots are robots interacting with humans not only in collaborative settings, but also in personal settings like domestic services and healthcare. Some social robots simulate feelings (companions) while others just help lifting (assistants). However, they often incite both fascination and fear: what abilities should social robots have and what should remain exclusive to humans? We provide a historical background on the development of robots and related machines (1), discuss examples of social robots (2) and present an expert study on their desired future abilities and applications (3) conducted within the Forum of the European Active and Assisted Living Programme (AAL). The findings indicate that most technologies required for the social robots' emotion sensing are considered ready. For care robots, the experts approve health-related tasks like drawing blood while they prefer humans to do nursing tasks like washing. On a larger societal scale, the acceptance of social robots increases highly significantly with familiarity, making health robots and even military drones more acceptable than sex robots or child companion robots for childless couples. Accordingly, the acceptance of social robots seems to decrease with the level of face-to-face emotions involved.
Social robots not only work with humans in collaborative workspaces – we meet them in shopping malls and even more personal settings like health and care. Does this imply they should become more human, able to interpret and adequately respond to human emotions? Do we want them to help elderly persons? Do we want them to support us when we are old ourselves? Do we want them to just clean and keep things orderly – or would we accept them helping us to go to the toilet, or even feed us if we suffer from Parkinson’s disease?
The answers to these questions differ from person to person. They depend on cultural background, personal experiences – but probably most of all on the robot in question. This book covers the phenomenon of social robots from the historic roots to today’s best practices and future perspectives. To achieve this, we used a hands-on, interdisciplinary approach, incorporating findings from computer scientists, engineers, designers, psychologists, doctors, nurses, historians and many more. The book also covers a vast spectrum of applications, from collaborative industrial work over education to sales. Especially for developments with a high societal impact like robots in health and care settings, the authors discuss not only technology, design and usage but also ethical aspects.
Thus this book creates both a compendium and a guideline, helping to navigate the design space for future developments in social robotics.
Robots and automata are key elements of every vision and forecast of life in the near and distant future. However, robots and automata also have a long history, which reaches back into antiquity. Today most historians think that one of the key roles of robots and automata was to amaze or even terrify the audience: They were designed to express something mythical, magical, and not explainable. Moreover, the visions of robots and their envisioned fields of application reflect the different societies. Therefore, this short history of robotics and (especially) anthropomorphic automata aims to give an overview of several historical periods and their perspective on the topic. In a second step, this work aims to encourage readers to reflect on the recent discussion about fields of application as well as the role of robotics today and in the future.
