Today robots are disposing of bombs, cleaning up nuclear waste, clearing minefields, exploring both the sea and outer space, and even doing spy missions. How far off is the perfect android? And—perhaps most important of all—could robots take over the world? In this program, robotics experts from Carnegie Mellon University’s Robotics Institute, Los Alamos National Laboratory, NASA, and MIT discuss how they design and engineer robots. Nanotechnology and self-replicating machines are also addressed.
