SISTEMAS E TECHNOLOGIAS DE INFORMACAO: ACTAS DA 4A CONFERENCIA IBERICA DE SISTEMAS E TECNOLOGIAS DE LA INFORMACAO
Abstract
The goal of this paper is to discuss the usage of distributed architecture for the Lego NXT robots. This platform is very interesting because it provides standard hardware for configurable mounting of several sensors and actuators. The presented work characterizes sensors and actuators and identifies limitations of the stand-alone architecture. In order to maximize usefulness and go beyond the identified limitations, a distributed computing architecture was developed that allows the Lego NXT to address complex missions. The distributed architecture makes use of two different programming environments. The described architecture was tested in a sample self localization task.

Abstract
This paper presents a case study of a web application for inventory management of electronics laboratories. The iLab project efficiently manages the inventory, requests, users (borrowings, purchases, etc.) and associated historic and workflow information. This enables users to queue requests and track their status. This project differs from the existing applications from this kind, since it not only serves administrative proposes, but also the users requirements. It was also developed with tools that ensure ease of development and deployment, while maintaining high performance, stability, security and future growth. In order to ensure a low "Total Cost of Ownership" application, freeware and web based tools were used. Future work includes Business to Business communications with large suppliers and optimization of the information stored in the database.

Abstract
This paper presents an innovative software called FEUP Fuzzy Tool. It was developed by teacher and students as an attempt to provide means to easily control non-linear plants and Multiple Input Multiple Output systems under soft real time constraints with the advantages offered by Fuzzy Logic controllers such as the usage of linguistic variables. The tool was partially developed in the classes and is currently used for investigation and educational purposes. This document discusses the features recently added to the toolbox, highlighting some very interesting capacities such as the capacity to export the developed fuzzy controllers to embedded systems. It is also given some insight of what it is currently been developed.

Abstract
This paper intends to demonstrate the development of and easy-to-use local human-machine interface that would allow any user to control all kinds of service robots intuitively. This interface is based on the Nintedo Wii remote controller and consists of three operating modes: a steering wheel, an infra-red monitor and a movement identifier. These modes were tested on a cleaning robot and they led to very satisfactory results, proving that the Wiimote is an inexpensive and interesting way of making this kind of interfaces.

Abstract
Interactive whiteboards are gaining importance in our society, both at a business level and, especially, at an educational level. However, the products offered by the major manufacturers have a major barrier to their acquisition: very high prices. There is an urgent need to use new technologies in order to provide solutions that present the same performance levels than typical interactive whiteboards, but with a significantly reduced cost. Throughout this paper the steps taken for the development of an innovative low-cost interactive whiteboard are described. The proposed system is based on the Wii Remote command of the Nintendo Wii video-game console. This command, although very inexpensive has an infrared camera, and supports Bluetooth communication. The system control is based on a wireless device, based on infrared emitters, which supports most of the mouse events. A complete whiteboard application was also developed using Borland Delphi for Windows. This application may be used with either one or two Wiimotes and has a very simple and efficient calibration method. The application also includes viewing capabilities of some of the Wiimote characteristics, as well as a flexible Notebook to increase its range of possible uses. The results obtained through a survey conducted to a small set of whiteboard users were very positive indicators about the acceptance of the inexpensive solution proposed.
