"If aliens had access to YouTube they would think the Earth was populated by robots." But as robotics expert Massimiliano Versace told a group at NASA Langley, that is not true – yet. And it is primarily because there are three barriers or "miracles that need to happen.
For robots to become as commonplace as they were in the 1960s TV show, "The Jetsons," Versace says engineers need to develop a smart mind, a powerful brain and an inexpensive body. The role model for this kind of robot in real life, as in fiction, is the human being.
