Abstract

In this paper, we consider “Wall-Bouncing” task in which we repeat the process of hitting the ball that rebounds from the wall and the floor as a typical example of dexterous batting tasks. Through the stability analysis of a discrete system, we reveal that required dexterity varies depending on the location of equilibrium points, that is, the shape of the ball trajectory. A feedback control scheme for the racket at the moment of impact is also proposed to continue “Wall-Bouncing” task under disturbances.
