The Goalkeeper’s Fear of the Nets
Journal of Hand Surgery, 1994The soccer goalkeeper is particularly prone to injuries of the hands. We report three cases in which soccer goal-posts were the cause of a hitherto unrecorded type of accident, which resulted in severe ring avulsion injuries requiring surgical amputation or replantation.

Color Based Object Segmentation on Wheeled Goalkeeper Robot
Asia Pacific Symposium on Intelligent and Evolutionary Systems, 2021The ball detection system is a basic ability that must be possessed by soccer player robots, including goalkeeper robots. With the ball detection system, the robot can find out the position of the ball on the field.

Humanoid Goalkeeper: Learning from Position Conditioned Task-Motion Constraints
arXiv.orgWe present a reinforcement learning framework for autonomous goalkeeping with humanoid robots in real-world scenarios. While prior work has demonstrated similar capabilities on quadrupedal platforms, humanoid goalkeeping introduces two critical ...

Sensor-based Detection and Classification of Soccer Goalkeeper Training Exercises
ACM Trans. Internet Things, 2020Many goalkeeper trainees cannot afford a personal human coach. Hence, they could benefit from a virtual coach that provides personalized feedback about the execution of their training exercises.

The influence of goalkeeper's height on soccer performance: A gender-based analysis
International Journal of Sports Science & CoachingThe difference in height between men and women goalkeepers (GKs) may influence goalkeeper performance, particularly when considering that both genders compete using goal frames of identical dimensions. The primary objective of this study was to establish

The Human Müller-Lyer Illusion in Goalkeeping
Perception, 2008We examined whether a goalkeeper can influence a penalty-taker's actions by assuming postures that mimic Müller-Lyer configurations. The results of two studies indicate that (i) goalkeeper posture affects the perception of the goalkeeper's height in a manner consistent with the Müller-Lyer illusion; (ii) this influences penalty-taking accuracy; and ...

The goalkeeper is one of the players that integrate the defensive system against the 5x4+G attack (line-goalkeeper), a strategy commonly used by coaches in the final minutes of the match to increase the chances of scoring goals. Therefore, the objective of this study was to describe the tactical-technical performance of the elite futsal goalkeeper in ...

On the control of a wheeled mobile robot goalkeeper
IEEE Conference on Robotics, Automation and Mechatronics, 2004., 2005This paper deals with the control of a wheeled mobile robot goalkeeper, where the goalkeeper's task is to intercept the ball before it goes inside the goal. The control law is based on the use of the kinematics equations and some geometrical rules. In our control strategy, the goalkeeper moves in a predefined path which corresponds to a rendezvous ...
