SIRS'2000 was attended by 60 participants and 42 papers from five continents were presented on topics ranging from communications and sensing, control, learning and behaviour to localisation, navigation, multiple robots and vision. SIRS'2000 was privileged to have three distinguished speakers: Ulrich Nehmzow from The University of Manchester, speaking on ''Novelty Detection for Robot Neotaxis''; Terrance Boult from Lehigh University, USA, speaking on ''Omnidirectional Video Applications''; and Cynthia Breazeal from the MIT AI Laboratory speaking on ''Humanoid Robotics Research at MIT''. As is customary, a selection of the best contributions, as chosen by participants of SIRS'2000, appear in this special issue of Robotics and Autonomous Systems.

This document presents the design and implementation of our SSL Robosoccer Team -RoboTurk. We explain the three main components of our architecture: Vision, AI and Hardware Systems.
RoboCup is an international initiative with the main goals of fostering research and education in Artificial Intelligence and Robotics, as well as of promoting science and technology to world citizens. The idea is to provide a standard problem where a wide range of technologies can be integrated and examined, as well as being used for project-oriented education, and to organize annual events open to the general public, where different solutions to the problem are compared. The 8 th annual of RoboCup -RoboCup2004 -was held in Lisbon, Portugal, from 27 June to 5 July. In this paper a general description of RoboCup2004, namely summaries concerning teams, participants, distribution per leagues, main research advances, as well as detailed descriptions for each league, are presented.
The present work considers the development of a wheelchair for people with special needs, which is capable of navigating semi-autonomously within its workspace. This system is expected to prove useful to people with impaired mobility and limited fine motor control of the upper extremities. Among the implemented behaviors of this robotic system are the avoidance of obstacles, the motion in the middle of the free space and the following of a moving target specified by the user (e.g., a person walking in front of the wheelchair). The wheelchair is equipped with sonars, which are used for distance measurement in preselected critical directions, and with a panoramic camera with a 360 degree field of view, which is used for following a moving target. After suitably processing the color sequence of the panoramic images using the color histogram of the desired target, the orientation of the target with respect to the wheelchair is determined, while its distance is determined by the sonars. The motion control laws developed for the system use the sensory data and take into account the non-holonomic kinematic constraints of the wheelchair, in order to guarantee certain desired features of the closed-loop system, such as stability. Moreover, they are as simplified as possible to minimize implementation requirements. An experimental prototype has been developed at ICS-FORTH, based on a commercially-available wheelchair. The sensors, the computing power and the electronics needed for the implementation of the navigation behaviors and of the user interfaces (touch screen, voice commands) were developed as add-on modules and integrated with the wheelchair.
Abstract: This paper describes the architecture and current capabilities of Carl, a prototype of an intelligent service robot, designed having in mind such tasks as serving food in a reception or acting as a host in an organization. The approach that has been followed in the design of Carl is based on an explicit concern with the integration of the major dimensions of intelligence, namely Communication, Action, Reasoning and Learning. The paper focuses on the multi-modal human-robot communication capabilities of Carl, since these have ...
