Ball Motion Control in the Table Tennis Robot System Using Time-Series Deep Reinforcement Learning
IEEE Access, 2021 One of the biggest challenges hindering a table tennis robot to play as well as a professional player is the ball’s accurate motion control, which depends on various factors such as the incoming ball’s position, linear, spin velocity and so

Investigation of the Aerodynamic Drag of Baseballs with Gyro Spin [PDF]
The 13th Conference of the International Sports Engineering Association, 2020 The following considers drag measurements of baseballs with backspin (spin axis horizontal and normal to trajectory) and gyro spin (spin axis parallel to trajectory) orientations. Balls were propelled through still air in a laboratory setting at 36 m/s and spin ranging from 1250 rpm to 1750 rpm.

Spin Rate Measurements in Cricket Bowling Using Magnetometers
Proceedings, 2020 The ability to measure and classify spin has been of great interest to cricket organizations, coaches, and athletes. While video is common, an alternative approach is to use 3D motion capture analysis with reflective spheres, which changes the ...

Aerodynamic Analysis of a Spinning Missile with Dithering Canards [PDF]
Journal of Spacecraft and Rockets, 2002 A generic spinning missile with dithering canards is used to demonstrate the utility of an overset structured grid approach for simulating the aerodynamics of rolling airframe missile systems. The approach is used to generate a modest aerodynamic database for the generic missile.
