Image processing applied to a robotic football team
Autonomous mobile robots are ever increasing their number of different applications, even in ludic applications or in sports. In the last few years, several robotic football competitions have been organised with participating teams from all over the world. This paper describes a team of Autonomous Mobile Robots which play football, developed by
the Group of Automation and Robotics at the Industrial Electronics department (School of
Engineering) of the University of Minho, in Guimarães (Portugal). In these competitions
each team is free to use and/or build all the different electronics, sensory systems, playing
algorithms, etc. as far as they cope with the rules imposed by the organisation. From every team new ideas emerge, sometimes the most incredible ones, but proving in the end that they work. These competitions proved to be very fruitful scientifically as well as very mediatic

Robot Football Team from Minho University
This paper describes an Autonomous Mobile Robot team which plays football, developed by the Group of Automation and Robotics at the Industrial Electronics department of the University of Minho, in Guimarães (Portugal). In this competition each team is free to use and/or build all the different electronics, sensory systems, playing algorithms, etc. as far as they cope with the rules imposed by the organisation. Instead of using several
different sensors increasing electronics complexity, this team decided to use only one major sensor: a vision system with a small colour camera. All the image processing algorithms were developed from scratch and they consist on
the heart of the whole project. This vision system uses an innovative approach: in order to see the whole field, a convex mirror was placed at the top of the robot looking downwards with the video camera looking upwards towards the mirror. This way, the robot can see all around itself with a top view, which means continuous vision of the ball, goals and other robots.(undefined
MINHO robot football team for 2001
This paper describes an autonomous robot football team. The work is being carried out since 1998. It describes the hardware used by the robots, the sensory system and interfaces, as well as the game strategy. Data acquisition for the perception level is carried out by the vision system, and the image processing system is described. Two cameras are used requiring sensorial fu-sion. With this architecture, an attempted is made to make the autonomous ro-bots more real world intelligent. These robots have a kicker with controlled power, which allows passing the ball to a teammate with controlled distance and direction.(undefined
Minho robot football team
Research and development in the robotics field can be greatly improved by attracting people with different challenges. RoboCup consists of a new challenge in which a team of robot players are supposed to play football with similar rules to the human football. This paper describes an Autonomous Mobile Robot Minho team solution. The robots were designed and developed by a group of undergraduate students from the Group of Automation and Robotics from the Industrial Electronics Department of the University of Minho, in Guimarães (Portugal). They were all built (electronics and mechanics) and programmed from scratch with a reduced budget. The main advantage of these robots consists on the image acquisition and processing. It uses a video camera pointing upwards to a convex mirror facing down. With this technique, most of the field is visible, facilitating the strategy of the game

A indústria de calçados de Nova Serrana (MG)
On the basis of previous statistical work with data and information from RAIS - Relação Anual de Informações Sociais, characterizing the Nova Serrana shoe industry as a local production system, and the results of a field research work with visits and interviews in local firms and institutions, this paper studies the Nova Serrana local production system as a whole as well as its firms and supporting institutions. The objective is to bring empirical evidence to guide public policy and private actions with a view to upgrade the local system in two spheres: (1) productive and technological, and (2) institutional and organizational. With this purpose in mind, this paper first characterizes and describes the local system in terms of location, adjoining influenced areas, logistics, population and number of jobs, history and evolution, production structure, supporting institutions, and social, cultural and political contexts. Next, the paper characterizes local firms in terms of size, product development, trading system, cooperation between rival firms, interactions with suppliers, sources of information for product development and on market trends and production technologies, practices and policies with regard to quality, financing, and other aspects. Finally, the paper summarizes the most relevant issues for policy measures and private actions by local firms and institutions
La proyección de la tolerancia en las sociedades democráticas: el controvertido uso de símbolos religiosos en espacios públicos
La tolerancia como principio de convivencia social es esencial para una vida sana, en medio de la diversidad de las formas de pensar y de actuar. La Tesis doctoral titulada La proyección de la tolerancia en las sociedades democráticas: el controvertido uso de símbolos religiosos en espacios públicos de D. Sergio Humberto de Quadros Sampaio examina el origen, la evolución y el momento actual del principio de la tolerancia, con tres propósitos: a) delimitar su concepto; b) descartar las eventuales "impurezas" en su construcción; c) estudiar las implicaciones y proyecciones de la tolerancia en las sociedades plurales propias de las democracias actuales. La polémica por el uso de los símbolos religiosos en los espacios públicos constituye una manifestación de ello
