 Poster: A snowHead
|
Japanese researchers have designed a robot that could help to establish how our joints work during ski turns. The researchers, from Kanazawa University, have taken the first steps towards developing a robot experimental system that could ultimately serve as a model to help skiers improve their own skiing technique. ...Their research is published in a recent issue of Sports Engineering.

Obviously A snowHead isn't a real person

Well, the person's real but it's just a made up name, see?

| (PhysOrg.com) -- Watching an Olympic skier perform a downhill slalom, turning smoothly around the flags, makes the sport seem just as much an art as a science. Although advanced skiers know how to turn effectively, the exact physical mechanisms involved remain elusive, as there is no complete set of objective criteria to define joint motions, posture, and all the other motions that go into making the turn. To try to gain a better understanding of the kinematics of optimized skiing, researchers have recently built a ski robot that can simulate the movements of professional skiers, allowing for direct measurements of the variables involved. |
Utter tosh . . . this is a barely a step up from V8's Boy's Own Mechano kit and it certainly does nor cannot reproduce the complex mechanical relationships in the foot, leg and pelvic joints and obviously not the huge counterbalance we all have above the waist.
If they can get money for this crappy level of research it's time I applied for a grant

Or even that no two humans are the same structuraly and are asymetric even on their own.

Some more than others

Anyway, snowHeads is much more fun if you do.

Awesome, hahahahahahahaha, can't wait for the BZK Crew to get their toothless grins into this one.

I think you're being hard on the researchers, Masque. Although it is obviously difficult to model all the subtleties and variation of the human anatomy, you have to start somewhere; that's the point about modelling, it's an approximation. Whether the physical robot is a better approach than simulation may be a moot point. But I would hope some interesting results come from the project.

A robot will however provide constants that we are unable to get from human subjects.

espri, SMALLZOOKEEPER, Constants are the one situation that doesn't exist in skiing . . . except the constant existence of a feedback loop between the snow surface and the skier's brain . . . which itself is anything BUT in a constant condition. As far as the article goes, this research will provide nothing more than relatively simple physics and geometry can provide. . . and that's certainly not the definition of the 'Art of Skiing'
SMALLZOOKEEPER, you should know better given your background and experience.

Masque, The main non constant in skiing is the human factor (fatigue-condition etc), so in this instance, the principal non constant is to be replaced. Other non constants such as snow pack and line shouldn't be too difficult to factor into the results.
Masque, You should know better, given my background than to point out that i should know better, blah, blah, blah.

...acceleration due to gravity? A varying g would be a fresh challenge to everyone.

And love to help out and answer questions and of course, read each other's snow reports.

Masque, I don't expect the robot can telemark!

Did it say Robot or Robert.
The latter we have and Rob@rar seems to be leading the field at the moment
