A robot is machine designed to work like a living person. The word robot was actually invented in 1920 by Karel Capek, a Czechoslovakian writer. But although the word is quite new, the idea of machines acting like people is very old. In the second century BC, Philon of Byzantium designed statues that performed clever tricks. Today throughout the world thousands of real robots do many important tasks that help people. Robots can do many of the things that people do, as well as some things people can't do. Many of the tasks that robots perform are boring or actually unhealthy for people. Some robots are built to explore places too dangerous for people to visit. They can take pictures and send back useful information without putting people at risk. One of the areas where robots explorers are used extensively is in space. Astronauts need special equipment to survive in space. Robots do not need air, water or food. They can work on distant planets keeping in touch with Earth by radio signals. NASA's Sojourner Rover was the very first robot to travel across part of another planet. In 1997, the six-wheeled rover explored part of the surface of Mars. The test robot Afghan Explorer may one day visit war zones. Working as a war reporter, it could send pictures and interviews back to a TV station in a safer place. The Dante 2 is similar to the Afghan Explorer. This eight-legged robot can climb into the crater of a red-hot volcano to collect gas samples(样本) and take photos with its eight cameras. Nomad Rover, another robot explorer, is the size of a small car. It has trekked through hot deserts and icy lands on it own, collecting information for scientists at home. Many robots work underwater. They map the ocean floor, monitor sea life or find sunken wrecks(残骸). These robots can travel deep underwater far more easily than people. Robots can stay underwater for many days at a time and travel hundreds of kilometres exploring the oceans. Underwater robots, such as Deep Drone, can travel to the ocean floor and help recover crashed aircraft or sunken ships. Deep Drone can travel around 40 times deeper than unprotected human divers. Some robots are rescue robots: they can save lives. They do this by fighting fires, searching for survivors after disaster, or handling dangerous objects such as unexploded bombs. Bomb disposal robots can look at suspect packages with their cameras. They relay the information to someone at a safe distance. As robot technology advances, our robots are becoming smarter and are able to help us with more and more aspects of our lives. Robots have enhanced our work efficiency greatly. Robots won't always be machines hidden away in dangerous factories. Work is already being done to develop robots which will help us in our kitchens or on our farms.
