Robots get schooled by teenage girl

At a conference for the International Society for Optical Engineers in San Diego on Monday, three different robotic arms lost an arm wrestling contest to a 17 old high school girl. While two of the arms only lasted about 4 seconds with the student, a third arm made by Environmental Robots Inc. lasted 26 seconds in the match before being defeated. All the arms used special artifical muscles made from electroactive polymers, which change shape from either electrical or chemical stimulus. Read more about here.
