In Robocup, The most important sensor on humanoid robot soccer is a camera. The camera serves as the eyes of the robot as well as in humans. This camera is used by the robot to detect the ball. The task of Humanoid Robot Soccer as a Goalkeeper is to keep the goal and must be able to block a ball that came directly to the goal from many directions so the ball is not got into the goal. As already...

Accuracy and speed of movement is required for a goalkeeper robot in the Robocup soccer competition. Moreover, instability and robustness of goalkeeper robot is often a problem in itself that often arise especially if the robot is a humanoid robot. There are various methods on how to improve the performance of movement of humanoid robot have been actively studied. So now we propose how to optim...

We welcome and appreciate the comment by Braun and Schmidt on our recent correspondence about the gambler's fallacy in goalkeeper behaviour during penalty shoot-outs. Braun and Schmidt assert that the binomial is more appropriate for analysing the data than our resampling approach. Their analyses appear to assume that dive direction is binomially distributed with a probability of 0.5. In fact, ...

This paper discusses a potential security issue in common operating system and application environments regarding dynamically attached devices and device interfaces. A set of countermeasures for the identified threats is described along with the integration of countermeasures into a policy-based security infrastructure; finally, an implementation of the countermeasure in the form of a policy en...

This paper presents a global vision based optical sensing system for identifying and intercepting moving objects. Using a color thresh-holding identification algorithm, the system can detect the position and angle of moving objects. The vision processing is done in real-time, effectively within 16.67ms sample time of an interlaced NTSC video image. Incremental tracking is employed to save on th...

Goalkeepers have a very big role in the game of football. Attack and defense football starts from goalkeeper. The Goalkeeper just has good concentration speed to play According observations made by researchers, obstacles that exist goalkeepers are ability reaction performance during match due lack variation training method. Therefore, with goalkeeping training, it is expected be able train skil...

This project, which was written at " Instituto Superior Técnico " (ISR) in Lisbon, Portugal, addresses the improvement of a goalkeeper for the " RoboCup Middle Size League ". The goalkeeper is one of four robots in the team at ISR. Each of the robots are controlled using a set of behaviours according to the role of each robot in the team. The set of behaviours and their relations is defined in ...

Goalkeeper (GK) is an expert in soccer and goalkeeping is a complete professional job. In fact, achieving success seems impossible without a reliable GK. His effect in successes and failures is more dominant than other players. The most visible mistakes in a game are those of goalkeeper's. In this paper the expert fuzzy system is used as a suitable tool to study the quality of a goalkeeper and ...
