     Guide dogs are good friends and helpers for blind people. Now, a new kind of robot can also do the

same job.

     NSK, a Japanese robotics company, is hard at work on a robot guide dog. The robot makes good

use of wheels on its four legs to roll (滚动) around on the floor. It can also lift its legs to climb up and

down stairs.

     Blind people can give orders to the robot by touching handgrips(手柄). The robot also talks in a

woman's voice to let its human owner know what's going on. Such robots will probably never take the

place of real dogs, but they have their own advantages. They can use GPS and street maps to lead their

owners to the places they want to go.
