In recent years, skiing turns are researched from various viewpoints. However, mechanism of the skiing turn remains to be completely elucidated in spite of considerable research. Furthermore, mechanical models derived by using the approximate expressions do not match to an alpine skiing turn and results are not concretely reflected. Therefore, to facilitate theoretical consideration, the passive type skiing robot was developed. Some influences on the skiing turn such as the position of center of gravity and the ski shape are examined easily by using this robot. In this paper, we examined the dynamics of skiing turn to help skiers improve their abilities as athletes.
