Researchers show off laser-guided robot

The El-E robot looks like something you'd see in a Hollywood sci-fi flick: It's got two lenses spaced together just like eyes and a slender 5 1/2-foot-tall body. It spurts out wacky catch phrases when it accomplishes its goals. But unlike android movie stars, the El-E isn't designed to behave like a human. Rather, its focus is interacting with us. It simply grabs stuff you point at with a laser.
