Sorry, science fiction fans, but the "replicants" of the Blade Runner saga or the "terminators" of the eponymous action movie franchise are not on the horizon. "Don't imagine human-like, humanoid robots when you think of the future of robots," said Kim Sang-bae, the world-renowned robot scientist who developed a four-legged walking robot called "Cheetah," which has gained widespread media exposure. Not only is it impossible to develop human-like robots now, it may remain impossible in the future, according to Kim, a mechanical engineering professor at the Massachusetts Institute of Technology. While the ultimate stage of robotics may, indeed, be creating machines that can think and work on their own, there is a yawning gap between where robot technologies stand now and that final-stage development. In an interview with Asia Times, Kim predicted that the robot industry would continue to expand by creating robots which can do very specific things better than humans.
