The Controllable Ball Joint Mechanism
JSME International Journal Series C, 2006 A controllable ball joint mechanism with three rotational degrees of freedom is proposed in this paper. The mechanism is composed of three bevel gears, one of which rotates with respect to a fixed frame and the others rotate with respect to individual floating frames.

Optimizing simulation for lower limb motion during throwing in water polo
Mechanical Engineering Journal, 2015 The objective of this study was to clarify the optimized lower limb motion during throwing in water polo by the simulation. The flexion/extension angles of the hip joint around the ball release were optimized in order to maximize the ball velocity, which
