Cutting edge technology is on display at the Winter Olympics -- virtual reality, next generation cellphone capability and lots of robots. Professor Oh Jun-Ho helped design and build "Hubo," the humanoid robot that participated in the Olympic torch relay. At the Korean Institute of Science and Technology, NBC got a glance of researchers developing new robots that could be ready to go in a matter of years. Some of those robots are designed to go into disaster zones, others to help security teams. Robots on display at the games can already pour coffee, give directions and clean floors.
Innovation helped turn South Korea's economy from one of the poorest to one of the richest.
