From the press release:
- Six years ago a scientist at NASA's Jet Propulsion Laboratory in Pasadena, Calif., issued a unique challenge: build a robotic arm using artificial muscles that could arm wrestle a human. The results of that challenge will be determined next week, when three such robotic arms will "step into the ring" to compete against a 17- year-old high school student. The ultimate goal is to win against the strongest human on Earth.
- Electroactive polymers are simple, lightweight strips of highly flexible plastic that bend or stretch when put into contact with chemicals or electricity. They are quiet and shatterproof and can be used to imitate human muscle movements. A small team of scientists at JPL, in cooperation with research centers worldwide, are working to turn these plastic strips into grippers and strings that can grab and lift loads. JPL engineers are also hoping to build a rover with legs fitted with artificial muscles. The robot would be able to walk instead of rolling on wheels on planetary surfaces. "My hope is to see a rover run like a horse on Mars and climb steep mountains like a monkey, allowing us to reach distances and heights that are not possible with wheeled rovers," said Bar-Cohen who has chaired the conference for the past six years.
