The principle of an alpine skiing robot was applied to a teaching method of skiing. First, a skiing posture is changed from straight down-hill running to snow plow only by internally rotating bilateral hip joints. The posture is also changed from straight down-hill running to traverse by internally rotating the left hip joint and externally rotating the right hip joint or by internally rotating the right hip joint and externally rotating the left hip joint. A straight down-hill running posture, a snow plow posture and a traverse posture considered to be basic skiing postures are clarified to be the same postures by applying the improved skiing robot from a viewpoint of rotating hip joints.
　Also that approximately 45 degrees of the angle between the ski and the thigh are the most suitable for edging and rotating the ski and that only by rotating hip joints the skiing robot is able to show alpine skiing techniques such as snow plow, stem turn and parallel turn are clarified. In this study the skiing robot was improved to be a large size.
