Synthesis Theory and Optimum Design of Four-bar Linkage with Given Angle Parameters [PDF]
Mechanical Sciences, 2019 In this paper, a synthesis method is proposed for the 5-point-contact four-bar linkage that approximates a straight line with given angle parameters. The given parameters were the angles and the location of the Ball point.

Trajectory Minimum Touching Ball
CoRRWe present algorithms to find the minimum radius sphere that intersects every trajectory in a set of $n$ trajectories composed of at most $k$ line segments each. When $k=1$, we can reduce the problem to the LP-type framework to achieve a linear time complexity.

Rating Player Actions in Soccer
Frontiers in Sports and Active Living, 2021 We present a data-driven model that rates actions of the player in soccer with respect to their contribution to ball possession phases. This study approach consists of two interconnected parts: (i) a trajectory prediction model that is learned from real ...

Ball tracking and trajectory prediction system for tennis robots
Journal of Computational Design and Engineering, 2023 Abstract Recently, as the service robot market has grown, robots have emerged in various fields such as industry, service, and sports. In the field of sports, robots that can play with humans have been developed. We proposed a novel vision system for measuring the trajectory of a tennis ball and predicting its bound position, which can ...
