But unlike Sci-Fi robot movie stars, the El-E isn't designed to act human. It simply gets things you point at with a laser.
"The entire world becomes a point-and-click interface. Objects become buttons. And if you point at one, the El-E robot comes to get it for you," said Charlie Kemp, the director of Georgia Tech's Center for Healthcare Robotics and the robot's designer. "To command the El-E, the user points a laser at something for a few seconds. The robot responds with a beep and then zeros in on the target. Once there, it lifts a mechanical arm and grabs the object. It begins the return trip when the laser is pointed at the user's feet, and it looks for a human face before handing over what it picked up.
El-E works by using dozens of sensors, lasers and cameras that help it find its target item and judge the grip needed to retrieve it. A mechanized crane that can grab items from the floor or shelves is the mass of its slender body. It rolls around on three wheels, and it's all powered by a lone Mac mini, which sits in its base.
Researchers hope the laser-directed robot could someday open doors, switch light panels and guide patients, but it still has a way to go.
The robot's arm can only carry objects up to 1.2 pounds, and it has yet to be tested with sick patients. I know quite a few people can use this now such as a stroke victom thats only 26 years old and on his own.
