    Behaviour-Based Off-Road Robot Navigation
    (KI - Künstliche Intelligenz: Vol. 25, No. 2, 2011) Armbrust, Christopher; Proetzsch, Martin; Berns, Karsten
    This paper describes concepts for the control of the autonomous off-road vehicle ravon. The complexity of the target environment comprising rough terrain as well as vegetation requires capabilities reaching from low-level safety aspects to high-level planning. It is shown how the modular implementation using the behaviour-based architecture iB2C allows for the realisation of complex behaviour networks based on a concept for the uniform representation of sensor data. The effectiveness of the presented approach is briefly shown in a real-world experiment.

    I Don't Want Parents to Watch My Lessons" – Privacy Trade-offs in the Use of Telepresence Robots in Schools for Children with Long-term Illnesses"
    (Proceedings of Mensch und Computer 2024, 2024) Neumann, Paul; Büttner, Sebastian Thomas; Acosta, Luca Hernández; Reinhardt, Delphine; Prilla, Michael
    Telepresence robots offer great opportunities for children with long-term illnesses to continue attending school. Consequently, they are already used if children are absent for long periods. When designing such systems, the privacy of various stakeholders must be considered. However, conflicts often arise because the privacy requirements of different user groups cannot be fulfilled simultaneously. In this paper, we analyze the corresponding trade-offs that have to be made when designing telepresence robots under conflicting privacy requirements. We analyzed previous literature and held three workshops with different user groups (children, parents, teachers, head teachers, media educators, and supporting personnel) with and without experience with telepresence robots in schools. Based on the literature and the workshop results, we present four major privacy trade-offs we identified and discuss design approaches for them. With this work, we contribute to the design research on telepresence robots in schools by revealing the major privacy-related conflicts and potential design approaches to overcome the conflicts.

    Off-road Robotics—An Overview
    (KI - Künstliche Intelligenz: Vol. 25, No. 2, 2011) Berns, Karsten; Kuhnert, Klaus-Dieter; Armbrust, Christopher
    This article gives an overview of the current state of research in the field of off-road robotics. It focuses on techniques used in the areas of perception, environment representation, as well as navigation, and introduces different types of robot control systems. A presentation of different applications is given along with an outlook on future developments.

    Robot in the Mirror: Toward an Embodied Computational Model of Mirror Self-Recognition
    (KI - Künstliche Intelligenz: Vol. 35, No. 1, 2021) Hoffmann, Matej; Wang, Shengzhi; Outrata, Vojtech; Alzueta, Elisabet; Lanillos, Pablo
    Self-recognition or self-awareness is a capacity attributed typically only to humans and few other species. The definitions of these concepts vary and little is known about the mechanisms behind them. However, there is a Turing test-like benchmark: the mirror self-recognition, which consists in covertly putting a mark on the face of the tested subject, placing her in front of a mirror, and observing the reactions. In this work, first, we provide a mechanistic decomposition, or process model, of what components are required to pass this test. Based on these, we provide suggestions for empirical research. In particular, in our view, the way the infants or animals reach for the mark should be studied in detail. Second, we develop a model to enable the humanoid robot Nao to pass the test. The core of our technical contribution is learning the appearance representation and visual novelty detection by means of learning the generative model of the face with deep auto-encoders and exploiting the prediction error. The mark is identified as a salient region on the face and reaching action is triggered, relying on a previously learned mapping to arm joint angles. The architecture is tested on two robots with completely different face.

    Tabbi - A Tangible Interface for Educational Chatbots
    (DELFI 2020 – Die 18. Fachtagung Bildungstechnologien der Gesellschaft für Informatik e.V., 2020) Wollny, Sebastian; Schneider, Jan; Rittberger, Marc; Drachsler, Hendrik
    With the increasing popularity of Artificial Intelligence in educational research, chatbots seem to be a promising future technology that could help students with their daily problems. As part of Smart Learning Environments, they can be permanently accessible by natural language via a variety of interfaces. To investigate the property of "tangibility", we present TABBI, an interface for educational chatbots that allows students to interact with a physical robot. This robot interface will be used in future comparative studies to evaluate interaction possibilities with educational chatbots. In this paper, we describe the general idea and context of TABBI.
