George Devol who came from the USA designed the first programmable robot in 1969. It
meant that the robot age had started from then on.However, in about 989 BC,during westernZhou Dynasty, a Chinese man whose name was Yan Shi made a wood robot. It looked like areal man and it was able to do many actions. It was good at dancing and it has a heart, astomach and other things in its body. It also had teeth and hair. It could express its feelings byusing its eyes. Its eyes could move and could show love to women,but it couldn’t laugh. It wasprobably the earliest robot in the world.
Not all robots always look like humans.They have various shapes.They are clever andthey can do all kinds of jobs, especially difficult and dangerous jobs.They are widely used infactories,banks, hospitals and other places. In the future, robots will make fewer mistakes,even can correct themselves and they will be smarter. It’s possible that we will have a robot inour own home.They will do more things for us.We will have more free time to have a rest, torelax ourselves with the help of robots.
