Details of Arm wrestling robots

Six years ago, one scientist of the Jet Propulsion Laboratory of NASA indì an only competition: to construct a constructed robotico arm from muscles crafts them in a position to striking to trial of strength a human contender. Today finally the challenge has been concluded. After that three robotici arms have been moderate against one student of 17 years. The last challenge is to construct an artificial trial of strength in a position to more strongly defeating the man of the world.

To the time in which it the idea launch this competition, the Dr. Yoseph Bar-Cohen, physicist of the JPL, had in mind of giving a decisive impulse to the searches on polymers elettroatti to you (EAP), known also as flashed with lightning "muscles craft them", a particular type of plastic that it can change activated shape electrochemically. Of sure, Bar-Cohen did not expect a fast epilogue therefore. "Given the technology that we had in 1999, I thought would be intentional at least 20 years", has declared Bar-Cohen, by now renamed "Artificial Muscle Man".

The 3 arms craft them have been realize to you from investigators of the New Mexico and Switzerland in plastic and polymers, while a group of students of the Virginia Tech University di Blacksburg, in Virginia, has used fibers electrochemical gels and cells. The competition has been carried out in occasion of the 3 days of conferences on "Electroactive Polymer and Devices" that has had place from the 7 to 10 March slid to the Town and Country Resort & Convention Center di San Diego. All, part of the symposium "Smart Structures and sponsored Materials" from the International Society for Optical Engineering.

Meat and boneses of the human oppositore, Felsen Cream, student of the Coast Canyon High School di San Diego, to the end have had the better one on its adversaries elettroatti to you, struck in little second ones. The muscles theirs craft have shown them all put into effect them limits which had in part to the electric motors, still too much weak people, in part to one hydraulic and one pnemautica too much heavy, of difficult use in applications roboticses or prostetiche. A lot in the future developments of the EAP, much lighter and more similar to biological muscles is hoped.
