随着工业化的发展，机器人将被更加广泛地运用于生产和生活之中。让我们通过下面的这篇短文了解一下与机器人有关的基本知识吧！ Robot Facts What are robots? The word “robot” comes from the Czech word “robota” which means “forced work or labor”. We use the word “robot” today to mean any man-made machine that can perform work or other actions normally performed by humans. What do robots do? Most robots today are used to do jobs considered too dangerous and boring for humans.They are also used in factories to build things like cars and electronics.Some robots are even designed to explore underwater and other planets. Why use robots? The reason we use robots is that it is cheaper, easier and sometimes the only way that we can get things done.Robots can explore volcanoes, Mars and other places that are too dangerous for humans to go.Robots can also do one thing over and over again without getting bored.Another reason to use robots is that they never get sick and they don’t need to take a day off. What are robots made of? Well, robots can be made from a variety of materials including metals and plastics and most robots usually have at least 3 main parts： (1)The controller, also known as the “brain”， which is run by a computer program; (2)Mechanical(机械的) parts such as motors and wheels that make the robot move; (3)Sensors(传感器)—to tell the robot about its surroundings.These parts working together control how the robot operates.Without the controller or “brain”， motors and sensors, robots would not be able to fun_ction. Robot limitations(局限性). Unlike those in the movies, robots are unable to think or make decisions; they are only tools to help us get things done.But who knows what robots may be able to do in the future. Maybe you will design the “Super Robot” of tomorrow.
