(A) Vision for 2050 - Context-Based Image Understanding for a Human-Robot Soccer Match

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 with the 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

A reliability-based particle filter for humanoid robot self-localization in Robocup Standard Platform League

This paper deals with the problem of humanoid robot localization and proposes a new method for position estimation that has been developed for the RoboCup Standard Platform League environment. Firstly, a complete vision system has been implemented in the Nao robot platform that enables the detection of relevant field markers. The detection of field markers provides some estimation of distances for the current robot position. To reduce errors in these distance measurements, extrinsic and intrinsic camera calibration procedures have been developed and described. To validate the localization algorithm, experiments covering many of the typical situations that arise during RoboCup games have been developed: ranging from degradation in position estimation to total loss of position (due to falls, ‘kidnapped robot’, or penalization). The self-localization method developed is based on the classical particle filter algorithm. The main contribution of this work is a new particle selection strategy. Our approach reduces the CPU computing time required for each iteration and so eases the limited resource availability problem that is common in robot platforms such as Nao. The experimental results show the quality of the new algorithm in terms of localization and CPU time consumption.This work has been supported by the Spanish Science and Innovation Ministry (MICINN) under the CICYT project COBAMI: DPI2011-28507-C02-01/02.

Individual and coordinated decision for the CAMBADA team

Mestrado em Engenharia de Computadores e TelemáticaA coordenação em sistemas multi-robô é um aspecto crucial no futebol robótico. A maneira como cada equipa coordena cada um dos seus robôs em acções cooperativas define a base da sua estratégia. Este trabalho tem como foco o desenvolvimento da coordenação e estratégia da equipa CAMBADA. CAMBADA é a equipa de futebol robótico da modalidade RoboCup Middle Size League da Universidade de Aveiro. Foi desenvolvida pelo grupo ATRI, pertencente µa unidade de investigação IEETA. O presente trabalho baseia-se em trabalho desenvolvido anteriormente, tentando melhorar o desempenho da equipa. Cada robô da equipa CAMBADA é um agente independente e autónomo capaz de coordenar as suas acções com os colegas de equipa através da comunicação e da partilha de informação. O comportamento de cada robô deverá ser integrado na estratégia global da equipa, resultando assim em acções cooperativas de todos os robôs. Isto é conseguido através do uso de papeis(roles) e comportamentos(behaviours) que definem a atitude de cada robô e as acções que daí resultam. Novos papeis foram desenvolvidos para complementar a estratégia de equipa, e alguns dos papeis existentes foram melhorados. Também foram efectuadas melhorias em alguns dos comportamentos existentes. É efectu- ada a descrição de cada um destes papeis e comportamentos, assim como as alterações efectuadas. O trabalho desenvolvido foi testado nas competições do Robótica 2008 (o desenvolvimento não estava ainda concluído) e por fim nas competições do RoboCup'2008. A participação da equipa no RoboCup'2008 é analisada e discutida. A equipa consagrou-se campeã mundial, vencendo a competição da Middle Size League do RoboCup'2008 em Suzhou, China. ABSTRACT: Multi-robot coordination is one crucial aspect in robotic soccer. The way each team coordinates its individual robots into cooperative global actions define the foundation of its strategy. CAMBADA is the RoboCup Middle Size League robotic soccer team of the University of Aveiro. It was created by the ATRI group, part of the IEETA research unit. This work is focused on coordination and strategy development for the CAMBADA team. It is built upon previous work and tries to improve the team performance further. In CAMBADA each robot is an independent agent, it coordinates its actions with its teammates through communication and information exchange. The resulting behaviour of the individual robot should be integrated into the global team strategy, thus resulting in cooperative actions by all the robots. This is done by the use of roles and behaviours that define each robot attitude in the field and resulting individual actions. In this work, new roles were created to add to the team strategy and some of the previous existing roles were improved. Some of the existing behaviours were also improved to better fit the desired goals. Each role and behaviour is described as well as the changes made. The resulting work was put to test in the portuguese Robotica 2008 competition (while still in progress) and finally in the RoboCup'2008 world competitions. The performance of the team in the latter is analysed and discussed. The team achieved the 1st place in the RoboCup'2008 MSL world competitions
