In alpine skiing an athlete's performance or injury mechanisms are strongly influenced by ski
vibrations. Ski vibrations are mainly caused by irregularities of the ski-snow interaction (eg …

Dynamic analysis and trajectory optimization are of great significance for an understanding
of the alpine skiing mechanism as well as the improvement of skiers' performance. In this …

In this paper, we analyse the model of pure carving turns in alpine skiing and snowboarding
based on the usual assumption of approximate balance between forces and torques acting …

We studied perfect carving turns of alpine skiing using the simple model of an inverted
pendulum which is subject to the gravity force and the force mimicking the centrifugal force …

In this paper we propose a general control framework for ensuring stability of humanoid
robots, determined through a normalized zero-moment-point (ZMP). The proposed method …

In this paper, we present an advanced model of centrifugal pendulum where its length is
allowed to vary during swinging. This modification accounts for flexion and extension of …

Skiing is a popular recreational sport, and competitive skiing has been events at the Winter
Olympic Games. Due to its wide moving range in the outdoor environment, motion capture of …

Alpine skiing, especially alpine downhill, is one of the most extreme winter sports in terms of
high-speed and narrow winning margin, and its tracks are always located in mountainous …

In this paper we present a simple mathematical theory of carving turns in alpine skiing and
snowboarding. The theory captures the basic dynamics of carving runs and thus provides a …

In this paper we propose a novel method for ensuring stability of a skiing robot on a
previously unknown ski slope. The method is based on a null-space velocity control …
