Spin plays a pivotal role in ball-based sports. Estimating spin becomes a key skill due to its
impact on the ball's trajectory and bouncing behavior. Spin cannot be observed directly …

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 …

In highly dynamic tasks that involve moving targets, planning is necessary to figure out
when, where and how to intercept the target. In robotic table tennis in particular, motion …

Sports robots have become a popular research topic in recent years. For table-tennis robots,
ball tracking and trajectory prediction are the most important technologies. Several methods …

In recent years robotic table tennis has become a popular research challenge for image
processing and robot control. Here we present a novel table tennis robot system with high …

In this paper, we present a method for table tennis ball trajectory filtering and prediction. Our
gray-box approach builds on a physical model. At the same time, we use data to learn …

Ball spin estimation in sports is important for analyzing the game. Since spin is generally too
fast to be captured by a conventional camera a high-speed camera is often used to capture …

Spin plays a considerable role in table tennis, making a shot's trajectory harder to read and
predict. However, the spin is challenging to measure because of the ball's high velocity and …

Professional long drivers can hit golf balls to a speed of up to 350 km/h. Extremely short
exposure time is required to capture the objects moving that fast without blur. The very high …

In table tennis, the rotation (spin) of the ball plays a crucial role. A table tennis match will
feature a variety of strokes. Each generates different amounts and types of spin. To develop …
