In Japan(日本), people made a very special robot. People use it to help fix railways(铁路). It is very large and heavy. It can lift things up to 40 kilograms. It can reach as high as ten meters. The robot is on a crane(起重机). It has two hands. A person controls(控制) the robot with a remote control(遥控器) and a VR headset(虚拟现实头盔).
The special robot does difficult or dangerous work for people. In the past, workers sometimes fell from high places when they fixed railways. There was also another danger: some people were electrocuted(触电致死). The robot helps solve these problems. It can also save manpower(人力).
Now, the robot helps workers only in a few places in Japan. In the near future, it will help people in many places. It will help workers in other countries, too.
