This paper deals with the problem of planning the Center of Mass (CoM) trajectory of a humanoid robot while its feet follow an omnidirectional walking pattern. This trajectory should satisfy the dynamic stability criterion to ensure analytically that the Zero…

Computer vision is one of the most challenging applications in sensor systems since the signal is complex from spatial and logical point of view. Due to these characteristics vision applications require high computing resources, which makes them especially difficult to…

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…

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…

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 presents the application developed for humanoid robots which are used in therapy of dementia patients, as a cognitive stimulation tool. It has been created using BICA, a component oriented framework for programming robot applications, which is also described.…

This article describes a proposal to achieve fast robot learning from its interaction with the environment. Our proposal will be suitable for continuous learning procedures as it tries to limit the instability that appears every time the robot encounters a…

Nowadays, there are a lot of Spanish groups which are doing research in areas related with physical agents: they use agent-based technologies concepts, especially industrial applications, robotics and domotics (physical agents) and applications related to the information society, (software agents)…
