A Computational Framework to Predict the Soccer Ball Trajectory
Journal of Applied MathematicsWe consider the problem of computing the soccer ball trajectory, that is, given the initial velocity, the initial angular velocity, the wind velocity, and the soccer ball geometry, we compute the soccer ball positions at different times during the ball ...

Spin Observation and Trajectory Prediction of a Ping-Pong Ball [PDF]
2014 IEEE International Conference on Robotics and Automation (ICRA), 2014 For ping-pong playing robots, observing a ball and predicting a ball’s trajectory accurately in real-time is essential. However, most existing vision systems can only provide ball’s position observation, and do not take into consideration the spin of the ball, which is very important in competitions.

Dynamic Nonprehensile Manipulation of a Moving Object Using a Batting Primitive
Applied Sciences, 2021 To achieve human-level object manipulation capability, a robot must be able to handle objects not only with prehensile manipulation, such as pick-and-place, but also with nonprehensile manipulation. To study nonprehensile manipulation, we studied robotic
