| Research Abstract |
In order to develop snowboarding robots that can model, how a snowboarder on a snowboard perform turns, it is necessary to understand the basic mechanisms of snowboarding. Moreover, successful development of such models can have applications in the teaching and learning of snowboarding. Yet it must be noted that the motions of a snowboarder are complex, thus requiring effective modeling so as to get to the principles. Despite this problematic complexity, I have been able to develop snowboarding robots that now are at least capable to perform turns by means of simple and clear motions.
The snowboarding robots are of the following types : (1) a model with outriggers for repeated and automatic carving turns ; (2) a model with outriggers for repeated and automatic skidding turns ; (3) a proto-type model ; (4) a model with flexion (dorsi-flexion) and extension (plantar-flexion) of the ankles ; (5) a model with flexion and extension of the knees ; and (6) a model with flexion and extension of

the hips.
The proto-type model of a snowboarding system leans forward (to the front-side) or backward (to the back-side). The proto-type model performs a front-side turn, when the model leans to the front-side, and the model performs a back-side turn, when the model leans to the back-side. To perform a front-side turn, the model flexes the ankle (dorsi-flexion) and to perform a back-side turn, it extends the ankle (plantar-flexion). To perform a front-side turn, it extends the knee, and to perform a back-side turn, it flexes the knee. To perform a front-side turn, it flexes the hip and to perform a back-side turn, it extends the hip.
By means of construction, observation and analysis of such models, I can conclude some important aspects to snowboard motion. For example, the edging and displacement of the snowboarder's center of gravity to the inside of a turn are the important motions for achieving turns at snowboarding. Especially through displacement of the snowboarder's center of gravity to the front side of a snowboard, a snowboarder's ability to make a skidding turn is facilitated. Less
