    Social robotics: reality and virtuality in agent-based robotics
    This paper advocates the application of multi-agent techniques in the realisation of social robotic behaviour. We present the Social Robot Architecture, which integrates the key elements of agenthood and robotics in a coherent and systematic manner. This architecture seamlessly integrates real world robots, multi-agent development tools, and VRML visualisation tools into a coherent whole.

    NEXUS : Mixed Reality Experiments with Embodied Intentional Agents
    This paper seeks to erode the traditional boundaries that exist between the physical and the virtual world. It explores mixed reality experiences and the deployment of situated embodied agents that offer mediation in the control of, and interaction between, avatars. The NEXUS system is introduced which facilitates the construction and experimentation with mixed reality multi-character scenarios. The behaviour of such characters or avatars is governed by a BDI agent architecture that can effectively sense both the real and the virtual world overlay. Within this paper we describe the NEXUS infrastructure together with the technology set that envelops it. We outline the design and results from a series of mixed reality experiments that have been conducted using the NEXUS system.

    The social robot architecture: towards sociality in a real world domain
    This paper advocates the application of multi-agent techniques in the realisation of social robotic behaviour. We present an architecture which commissions agent-based deliberation without sacrificing the reactive qualities necessary in a real world domain, and which is situated within a social landscape through the use of an Agent Communication Language.

    Robot soccer anywhere: achieving persistent autonomous navigation, mapping and object vision tracking in dynamic environments
    The paper describes an ongoing effort to enable autonomous mobile robots to play soccer in unstructured, everyday environments. Unlike conventional robot soccer competitions that are usually held on purpose-built robot soccer "fields", in our work we seek to develop the capability for robots to demonstrate aspects of soccer-playing in more diverse environments, such as schools, hospitals, or shopping malls, with static obstacles (furniture) and dynamic natural obstacles (people). This problem of "Soccer Anywhere" presents numerous research challenges including: (1) Simultaneous Localization and Mapping (SLAM) in dynamic, unstructured environments, (2) software control architectures for decentralized, distributed control of mobile agents, (3) integration of vision-based object tracking with dynamic control, and (4) social interaction with human participants. In addition to the intrinsic research merit of these topics, we believe that this capability would prove useful for outreach activities, in demonstrating robotics technology to primary and secondary school students, to motivate them to pursue careers in science and engineering

    Agent chameleons: moving minds from robots to digital information spaces
    Agent Chameleons investigates the motivation, desire and possibility of agent migration and mutation between real and artificial spaces. The agent must be able to mutate and change its form and function depending upon the environment within which it is situated. The form inextricably dictates or constrains its behaviour and capabilities. This paper introduces the Agent Chameleon Architecture which supports agent migration and mutation.

    The AMPERE Algorithm : Area-based Masking with the PERformance Equation
    This paper is concerned with the employment of an autonomous and intelligent agent within the context of a 3-dimensional virtual environment. As the agent is immersed within the virtual environment, it empowers the 3D world with mechanisms to adjust itself to the specific needs of its user. Therefore, the agent serves as a middle layer between user and the environment. The 3-dimensional environment thus evolved into an intelligent user interface. We track user’s motion within this environment and present an equation upon which the agent classifies the user’s performance. Based upon this performance value, the agent autonomously determines if the user would benefit form system navigational support. The performance equation is based on an area-based mask that is applied on the trajectory image of the user’s movements. Within this paper we discuss the effects of applying different masks onto the trajectory image. We evaluate, why the actual shape of the mask is not as crucial to the performance measure as one might anticipate.

    Fusing realities in human-robot social interaction
    As robots become more and more embedded in our physical and social environment, their integration into our social interaction space necessitates mechanisms which manage these new social contexts. While considerable work has been invested in developing strong human-like robots in order to arguably augment the human-robot interaction experience, the core complexity and significant costs with such an approach render it difficult to justify for practical real-world applications. This paper discusses the use of augmented reality as a tool to bypass this issue and allow the designer, and subsequent user, to easily choose an aesthetic with associated social behavioural mechanisms. Not only does this allow a user to perceive an associated form with a robot, but also allows many people to perceive alternate forms for the same robot, a degree of social customisation which has been impossible until now.

    Future reasoning machines : mind and body
    Purpose – In investing energy in developing reasoning machines of the future, one must abstract away from the specific solutions to specific problems and ask what are the fundamental research questions that should be addressed. This paper aims to revisit some fundamental perspectives and promote new approaches to reasoning machines and their associated form and function. Design/methodology/approach – Core aspects are discussed, namely the one-mind-many-bodies metaphor as introduced in the agent Chameleon work. Within this metaphor the agent's embodiment form may take many guises with the artificial mind or agent potentially exhibiting a nomadic existence opportunistically migrating between a myriad of instantiated embodiments. The paper animates these concepts with reference to two case studies. Findings – The two case studies illustrate how a machine can have fundamentally different capabilities than a human which allows us to exploit, rather than be constrained, by these important differences. Originality/value – Aids in understanding some of the fundamental research questions of reasoning machines that should be addressed.

    What is a social robot?
    This paper discusses the concept of a social robot. Developing from recent work on physical embodiment, the necessity for a socially embodied robot is presented. Current work via the Social Robot Architecture seeks to develop and demonstrate these concepts.

    Ubiquitous realities through situated social agents
    In order to take the developing field of Social Robotics a stage further, this work investigates mixed reality in embodied social agents. The Virtual Robotic Workbench is employed which provides a versatile framework for experimentation in interoperability and cooperation between heterogeneous robots (real, simulated and virtual) and humans in multi-reality domains. Explicit social interaction, both between virtual and real robots and between robots and people, is supported.
