this paper describes a robust localization system, similar to the used by the teams participating in the Robocup Small size league (SLL). the system, developed in Object Pascal, allows real time localization and control of an autonomous omnidirectional mobile robot. the localization algorithm is done resorting to odometry and global vision data fusion, applying an extended Kalman filter, being this method a standard approach for reducing the error in a least squares sense, using measurements from different sources.

In this paper we present an experimental test bed for the development and evaluation of control systems for unmanned helicopters. the test bed consists of a small unmanned helicopter, mounted on a flying stand that permits all possible movements but prevents the helicopter from damaging or crashing. A fuzzy controller is developed in MATLAB and tested in the helicopter using the test bed. the controller is able to perform hovering and altitude control. Experimental results are presented for various test cases.

Robots intended for human-robot interaction are currently designed to fill simple roles, such as task completer or tool. the design emphasis remains on the robot and not the interaction, as designers have failed to recognize the influence of robots on human behavior. Cybernetic models are used to critique existing models and provide revised models of interaction that delineate the paths of social feedback generated by the robot. Proposed robot roles are modeled and evaluated. Features that need to be developed for robots to succeed in these roles are identified and the challenges of developing these features are discussed.

robotics is an interesting but difficult area for digital artists who generally don't have much academic background on electronics or computer programming. Digital art students normally use high-level application to program their visual and sonorous installations. this paper presents LegOSC - a tool that allows the control of the Mindstorms NXT robots from any application that uses the Open Sound control protocol which is implemented by most of those high-level applications. this allows artists to create works which incorporate robotic parts using the familiar programming environment.

In the near future, service robots will support people with different handicaps to improve the quality of their life. One of the required key technologies is to setup the grasping ability of the robot. this includes an autonomous object detection and grasp motion planning to fulfil the task of providing objects from any position on a table to the user. this paper presents a complete system, which consists of a fixed working station equipped with a laser-range scanner, a seven degrees of freedom arm manipulator and an arm prothesis as gripper. the contribution of this work is to use only one sensor system based on a laser-range scanning head to solve this challenge. the goal is that the user can select any defined object on the table and the robot arm delivers it to a target position or to the disabled person.

In this paper we present an approach for multi-robot cooperative exploration based on the potential field generated by several basic behaviours. When an unknown environment is explored the uncertainty in the localization normally grows, this fact may cause the failure of the Simultaneous Localization and Mapping (SLAM) algorithm, and thus constructing an useless and inaccurate map. the exploration algorithm described here considers the current knowledge of the environment, the location of the robots and the uncertainty in their positions in order to return to previously explored areas when it is needed. these actions definitely help the SLAM algorithm to build a precise map. Several simulations are presented that demonstrate the validity of the approach.

From the RoboCup goal of having a fully autonomous humanoid soccer team, it is possible to see many applications of the research in the Humanoid Soccer, such as the development of mechanical legs and arms and exoskeletons. the onboard vision algorithms for multi target tracking and the cooperative decision making of some Soccer Leagues can be used in squadrons of autonomous vehicles in a variety of missions. the algorithms for image processing of the Small Size League can be used in aerial or satellite images to track vehicles. the Simulation League allows the development of many intelligent agents applications. the formations and team play positioning of the Simulation League can be used to optimize the positioning of a squadron of autonomous vehicles. the research of Robotic Soccer fosters and strengthens the research in robotics, allowing and contributing to the development of many powerful applications which can great benefit the mankind.

We believe it is possible to create the visual subsystem needed for the RoboCup 2050 challenge - a soccer match between humans and robots - within the next decade. In this position paper, we argue, that the basic techniques are available, but the main challenge will be to achieve the necessary robustness. We propose to address this challenge through the use of probabilistically modeled context, so for instance a visually indistinct circle is accepted as the ball, if it fits well withthe ball's motion model and vice versa. Our vision is accompanied by a sequence of (partially already conducted) experiments for its verification. In these experiments, a human soccer player carries a helmet with a camera and an inertial sensor and the vision system has to extract all information from that data, a humanoid robot would need to take the human's place.

Many people with disabilities find it difficult or even impossible to use traditional powered wheelchairs independently by manually controlling the devices. Intelligent wheelchairs are a very good solution to assist severely handicapped people who are unable to operate classical electrical wheelchair by themselves in their daily activities. this paper describes a development platform for intelligent wheelchairs called IntellWheels. the intelligent system developed may be added to commercial powered wheelchairs with minimal modifications in a very straightforward manner. the paper describes the concept and design of the platform and also the intelligent wheelchair prototype developed to validate the approach. Preliminary results concerning automatic movement of the IntellWheels prototype are also presented.

Nowadays production flows are modular, each module in the enterprise being specialized and used to achieve a particular task. In many cases the modules are connected and materials are sequentially processed in each module resulting a final, unique product or assembly. One typical such production module is a flexible cell/system using multiple robots. In this structure, providing continuous service for applications is a key component of a successful robotized implementing of manufacturing. High availability (HA) is one of the components contributing to continuous service provision for applications, by masking or eliminating both planned and unplanned systems and application downtime. A high availability solution in robotized manufacturing provides automated failure detection, diagnosis, application recovery, and node (robot controller) re integration. the paper describes a platform which is a software product designed to control and supervise multiple robot-vision controllers using remote connections with a number of Adept Technology V+ controllers configured to use a high availability implementation, either located in a local network or via Internet.
