Narrator: This is Science Today. A team of scientists at the University of California Berkeley wants to make science fiction a reality - and they are off to a good start. Homayoon Kazerooni, a professor at the School of Engineering has developed the first wearable robotic device to enhance human strength, an idea he says has been around for a very long time.
Kazerooni: The whole idea of an exoskeleton evolved through fiction books and movies. And a great number of scientists have actually worked on this project. The very first one started at general electric during the 50's on a project called Hardy Man.
Narrator: Kazerooni's team has been working on the exoskeleton since 1994, and says they managed to succeed where other researchers have failed because of recent advances in computer and sensor technology.
Kazerooni: For example, the Berkeley exoskeleton has more than 40 sensors and all these sensors and actuators talk to each other via a small local area network. The communication is very fast, and that technology was not available during the Fifties.
