This task is accomplished using the virtual potential field, which direct the skier toward the next gate.
In this case, the model of the skier can be represented as a double inverted pendulum.
We proposed hierarchial control law, where the skier stability is of primary importance.
The most stable position of the skier is when the forces are equally distributed on both skis.
It was demonstrated, that with this modification we obtain similar path as an experienced human skier would do.
This membrane can be thought of as a snowboard and the red cell itself as an extraordinarily efficient skier.
Epidemiological investigations were performed on cohorts of schoolchildren, permanent residents and skiers visiting the area.
Expert skiers achieve velocities in excess of ten times their body height per second due to gravitational forcing.
