| Research Abstract |
The purpose of this study is to develop a model experiment system for ski motion using a robot that has similar joint mechanism and motion properties. For this purpose, a new robot which has same joint mechanism with a skier has been developed and then the relation between the turn motion and the various combinations of joint motions.
(1)A new ski robot which can make hip joint abduction and adduction, thigh rotation, knee joint flexion, lower leg twist and ankle flexion.
(2)For the automatic skiing system, speed sensor, load sensor and direction sensor have been developed. The direction sensor detects the angle between the skiing direction and earth magnetic field. Using the sensors, automatic motion start and force control have been performed.
(3)The relation between various motion pattern and turn movement. The time of the change of edging coincides with the time of turn direction change, Larger load applied on the downside leg in the later half cycle of the turn and it continues in the former half cycle.
(4)The ski motion of a top skier has been measured using shape tape, load cells. The characteristic of the top player on the combination of flexion-extension and thigh rotation has been revealed.
(5)Applying the characteristic motion of the top skier into the program of the ski robot, relatively certain turn has been performed.
