Abstract
This paper presents algorithmic methods to generate progressive, whip-type motions, characteristic of experienced humans in high-speed athletic activities such as throwing and striking. In deriving these methods, we deduce boundary conditions for dynamic quantities by analysing the motion of a two-link system. A control algorithm based on cascading gains is introduced and is shown to be efficient when compared to fixed-gain proportional control. Principles of energy redistribution within links are used to explain the mechanical advantage gained by a whip-type motion, and the efficiency of cascading gain control. The results can be applied in motion synthesis for animation which is demonstrated through simulation of a multi-link system. Our aim has been to obtain biomechanically plausible solutions which approximate natural motions. ©1996 by John Wiley & Sons, Ltd.
