We've seen robots destroy and conquer in movies, but we never thought that would come close to happening in the real world. After all, we've mostly seen them being built for such humanly tasks as painting and, well, vomiting.
But researchers at the University of California at Berkeley have developed a micro-size robotic muscle that is 1,000 times stronger than a human muscle.
They used a material called vanadium dioxide to produce the robot muscle. When heated to 152.6 degrees Fahrenheit, the compound changes from an insulator to a conductive metal, giving it a huge amount of strength during the transition.
This lets the robot muscle throw objects 50 times heavier than itself over a distance five times its length, all within 60 milliseconds -- faster than the blink of an eye. … Read more
