at Johns Hopkins University's Applied Physics Laboratory in Laurel, Maryland, have a new humanoid or human-like robot. Its name is Robo Sally. machine can be controlled from a distance and can be used do work that is dangerous for human beings. Robo Sally has long arms with human-like hands. She can use her fingers to up small objects, examine them in detail and do most things human hands can do. Each finger contains a tiny motor capable squeezing 20 pounds of pinch force, enough to defuse a bomb the direction of an operator. Robo Sally sits on a metal with wheels that let the robot move around, turn in tight and climb over small objects. Mike McLaughlin is the main investigator the Applied Physics Laboratory's Prosthetics Program. It was a difficult job. . McLaughlin says the robot hand had to have many small motors have the ability to do what a human hand does. It needed to have human-like strength. For search and rescue duties, Robo will be operated by a person using a wireless machine that far from the robot. The operator will also wear special glasses. glasses will permit the operator to see the robot's hands. Mr. says this kind of robot could be used in what he "dull, dirty or dangerous" situations where fine human finger movements are . Mr. McLaughlin says the technology is not fully ready yet. He that within five years, there will be some very big improvements. VOA Learning English, I'm Alex Villarreal.
