Robot revolution
The day that a robot wakes you up, cleans your room and walks your dog might still be a few decades （十年）off. But increasingly, engineers are saying that robots are going to make the leap from the factory floor to your family room.
Companies like Sony and General Electric are working on designs for small robots. Products like the Roomba, a robot that can clean floors, are flying off the shelves. On the cover of a recent issue of Scientific American magazine, Bill Gates predicted the “Dawn of the Age of Robots”.
What’s behind this new era (时代)? It’s partly a matter of technology. Devices that can recognize and respond to a human voice have been developed. There are now a few different ways for robots to move around. They can walk, crawl or ride on wheels. They are being made smaller and smaller. They are also becoming more and more energy efficient.
A bigger part of the story is on the demand side. From the day Robert Adler invented the television remote control in the 1950s, people around the world have tirelessly searched for ways to get lazier.
Also take into consideration the increasing wealth of rich people, the time appears ripe to introduce robots to ease our daily lives.
To be sure, robots that walk on two legs and talk like people are still too complex for our present engineering abilities. Today’s robot revolution is to make them for everyday use. Robots will do basic housework such as cleaning or gardening, or just help you have more fun on the basketball court.
What makes a robot different from an ordinary cleaning machine is not the presence of computer chips (芯片). Nowadays even your microwave has a computer chip. It is the ability to sense and make changes to the environment in real time.
For example, a floor-cleaning robot should be able to sense your scared cat and move out of the way. Today’s computing ability is, for the first time, able to make machines that could “think”, at least in certain limited ways.
