In this paper, we propose an original method to geoposition an audio/video stream with multiple emitters that are at the same time receivers of the mixed signal. The obtained method is suitable when a list of positions within a known…

To provide more efficient and flexible alternatives for the applications of secret sharing schemes, this paper describes a threshold sharing scheme based on exponentiation of matrices in Galois fields. A significant characteristic of the proposed scheme is that each participant…

MACSimJX provides the means for advanced modelling and development of multiagent driven control systems. This is achieved by drawing together two modelling tools used extensively in their respective communities. These are Simulink, a tool used for control systems development and…

The purpose of this study was to examine how children think about and attribute features of friendship to a robot after a brief interaction with one. Children visiting a science centre located in a major Western Canadian city were randomly…

The ability of building robust semantic space representations of environments is crucial for the development of truly autonomous robots. This task, inherently connected with cognition, is traditionally achieved by training the robot with a supervised learning phase. We argue that…

This special issue of the Journal of Physical Agents is devoted to multi-robot systems. Some might perhaps argue that the term should have been ”multi-agent systems” or ”physical multi-agent systems”, in accordance with the title of the journal. In any…

This special issue of the Journal of Physical Agents is devoted to human interaction with domestic robots. The form, features and future, of domestic robotic devices, from entertainment-based agents through to robotic cleaners, companions, assistants and helpers, are considered and…

In this work we present a reactive autonomous robot navigation system based only on omnidirectional vision. It does not rely on any prior knowledge about the environment apart from assuming a structured one, like indoor corridors or outdoor avenues. The…

The Workshop of Physical Agents intends to be a forum for information and experience exchange in different areas regarding the concept of agent in physical environments, especially applied to the control and coordination of autonomous systems: robots, mobile robots, industrial…

This paper briefly introduces a summary of the special session on Hybrid Reasoning and Coordination Methods on Multi-Agent Systems, held in conjunction with the 4th International Conference on Hybrid Artificial Intelligence Systems 2009 (HAIS’09). The research papers of this session…
