A mobile robot has always uncertainty about the world model. Reducing this uncertainty is very hard because there is a huge amount of information and the robot must focus on the most relevant one. The selection of the most relevant information must be based on the task the robot is executing, but there could be several sources of information where the robot would like to focus on. This is also ...

The difficulties associated with developing a competitive FIRA team using undergraduate students, spread across multiple sites are discussed. System modularisation and common interface standards are shown to be key elements for success. Details are provided of the approach used for each module with particular emphasis given to the vision system and time delays. A new prototype robot body design...

Since it’s beginning, Robot Soccer has been a platform for research and development of independent mobile robots and multi-agent systems, involving the most diverse areas of engineering and computer science. There are some problems to be solved in this domain, such as mechanical construction, electronics and control of mobile robots. But the main challenge is found in the areas related to Artif...

In this article we proposed an improved SIFT-based object recognition methodology for robot applications. This methodology is employed for implementing a robot-head detection system, which is the main component of a robot gaze direction determination system. Gaze direction determination of robots is an important ability to be developed. It can be used for enhancing cooperative and competitive s...

Position and angle errors are an obstacle to accurate, high-speed control of micro-robots in a robot soccer system. Systematic errors resulting from constraints on the global imaging system are identified, and their magnitude estimated. A full calibration procedure is proposed to minimise these errors that only uses information available from the soccer field. This calibration method has a resi...

In this paper the mathematical background of the developed robot soccer simulator is presented. It involves robot and ball dynamic behaviour and focuses mainly on their collisions study. Vital parts of the simulator are explained and modelled in more detail, beginning with the simple model of ball and robot motion and continuing with a more complex approximate collisions models, where the real ...

While embodied robotic applications have been a strong influence on moving artificial intelligence toward focussing on broad, robust solutions that operate in the real world, evaluating such systems remains difficult. Competition-based evaluation, using common challenge problems, is one of the major methods for comparing AI systems employing robotic embodiment. Competitions unfortunately tend t...
