Scientists have been trying for years without much success to create "seeing" robots.
Recently, however, researchers at the University of Rochester achieved two advances. The "Rochester Robot" now can judge depth and can maintain a steady image of a moving object.While robots are commonly used to perform routine tests again and again, the Rochester team wants to create a robot that can interact with its environment, as people and animals do. Vision is a basic, necessary tool.
Eventually, the team hopes the robot will be able to respond to and manipulate objects in its environment, such as balloons and toy trains.
