Estimation of aerodynamic coefficients for a ball by using characteristics of trajectory
Nihon Kikai Gakkai ronbunshu, 2014 We investigate estimation methods of aerodynamic coefficients for a ball in sports by using characteristic quantities of its trajectory. One method is based on the quantities representing the whole shape of trajectory while the other utilizes local ...

Trajectory-based Learning for Ball-in-Maze Games
CoRR, 2018 Deep Reinforcement Learning has shown tremendous success in solving several games and tasks in robotics. However, unlike humans, it generally requires a lot of training instances. Trajectories imitating to solve the task at hand can help to increase sample-efficiency of deep RL methods.

Soccer ball lift coefficients via trajectory analysis
, 2010 We performed experiments in which a soccer ball was launched from a machine while two high-speed cameras recorded portions of the trajectory. Using the trajectory data and published drag coefficients, we extracted lift coefficients for a soccer ball.

Acceptable range of timing error at bat-ball impact in baseball depends on the bat swing path
Frontiers in Sports and Active LivingIntroductionIn baseball, a common instruction emphasizes aligning the bat swing trajectory with the pitched ball trajectory near impact when viewed from the side. This alignment is believed to widen the acceptable range of timing error, thereby enhancing

Opponent Hitting Behavior Prediction and Ball Location Control for a Table Tennis Robot
Biomimetics, 2023 The hitting position and velocity control for table tennis robots have been investigated widely in the literature. However, most of the studies conducted do not consider the opponent’s hitting behaviors, which may reduce hitting accuracy.
