Recently, the number of alpine ski junior players in Japan has drastically decreased.\nThe causes include a decrease in ski areas and instructors, along with difficulty of early childhood\nalpine ski guidance. The alpine ski competition is not simply a glide on a slope. It requires\nunderstanding of ski deflection and skier posture mechanics. Therefore, a passive ski robot without\nan actuator was developed for junior racers of the alpine ski competition to facilitate understanding\nof the turn mechanism. Using this robot can elucidate factors affecting ski turns, such as the position\nof the center of gravity (COG) and the ski shape. Furthermore, a mechanism for changing the COG\nheight, the edge angle and the ski deflection is added to the passive turn type ski robot. The developed\nski robot can freely control the turn by changing those parameters during sliding.
