| Outline of Final Research Achievements |
We have developed; 1) A passive skidding-turn model of abduction and adduction of the hip joints, with inner rotation of the hip joints, 2) A passive skidding-turn model with inner rotation of the hip joints around the femur axes, 3) A passive skidding-turn model of inward lean with inner rotation of the hip Jointss. In terms of the performance of the passive skidding-turn models, keeping the bilateral hip joints of the skidding-turn model (which are rotated slightly inside with a double-lever mechanism of the four links of a quadric crank-chain), a sequential skidding-turn could be achieved with energy-less skiing. For the passive skidding-turn models, even if the rudder angle was applied to the top-lifted side, a turn could be achieved. Moreover, the direction of the turns of the skidding-turn model of inward lean with inner rotation of the hip joints corresponded overall to the direction of the steering of a ship.
