“…In the serving, the ball must bound in the own court, which is different from the rallying, and so it is harder to make the ball trajectory planning. In this paper, a prediction problem and a racket control problem for the serving task are formulated by three physical models: aerodynamic model with drag and Magnus terms [7], and table and racket rebound models [8]. The prediction problem is to predict a served ball's position, translational and rotational velocities in the opponent's court.…”
: This paper considers the serving task for the table tennis robot. Based on the physical models, the ball trajectory is formulated where the ball is hit by the racket and rebounds on the table in own court and in the opponent's court. Then the paper clarifies which variables among the ball's position, translational and rotational velocities can be controlled independently by the serving racket. Some numerical simulations verify the results work approximately well.

“…And three physical models have been established: the aerodynamics model (ADM) which considers both the drag and Magnus forces [6], the table rebound model (TRM) and the racket rebound model (RRM) [7]. Both rebound models characterize the variation of the ball's translational and rotational velocities before and after rebounding.…”

“…There are two physical models, the racket rebound model [7], [9] and the aerodynamic model [6]. The racket rebound model (RRM) expresses a relation between ball's velocities at the moment just before and after a racket strikes the ball.…”
: This paper mainly proposes a racket control method for returning a table tennis ball to a desired position with a desired rotational velocity. The method determines the racket's state, i.e., the racket's striking posture and translational velocity by using two physical models: the racket rebound model and the aerodynamics model. The algorithm of determining the racket's state is derived by solving nonlinear equations and solving a two-point boundary value problem of a differential equation. But this is not suitable for a real-time process because of large computing time. The paper proposed a modified algorithm which could be used for a real-time process by introducing a simple aerodynamics model. Numerical simulations and experimental results show effectiveness of the proposed methods.
