This paper proposes a behaviour-based approach for the motion control problem of sustainable and compliant Four-Wheel-Steering robots. Each wheel is considered to be an independent entity that must react according to some local rules. Motivated by the Virtual Components Approach, behaviours implement these local rules by means of a set of virtual elements(More)
This paper describes the DSAAR architecture, which aims the fast development and prototyping of multi-robot systems and it is based on Linux inter-process communication (IPC) mechanisms and multi-agent Jade software platform. This architecture is of special interest in domains where several heterogeneous actors have to interact both with and without(More)
Remote operations in harsh environments, such as those found in the search & rescue and humanitarian demining domains, achieve better results when a strong interaction among users and robots is considered. In addition, robots should be disposable and robust, which can be achieved through parsimonious design. This paper presents a multi-agent system to solve(More)
Human judgement is an integral part of the teleoperation process, heavily influenced by the rate in which commands are given to and the telemetry data is received from the robot. In this paper a multi-agent system for robot teleoperation is proposed. Several entities (e.g. robot or human) can easily be added and removed. In addition, this approach fosters a(More)
The traditional approach in electric generation is focused on centralized plants producing electricity which is transmitted and distributed over long distances through the networks. In contrast, using distributed energy resources, much smaller amounts of energy are produced by numerous small, modular energy conversion units, which are often located close to(More)
Teams of humans and robots pose a new challenge to teamwork. This stems from the fact that robots and humans have significantly different perceptual, reasoning, communication and actuation capabilities. This paper contributes to solving this problem by proposing a knowledge-based multi-agent system to support design and execution of stereotyped (i.e.(More)
