1. Read and translate the text.
When engineers devised a steam engine in the 18th century, some people said that they had already invented everything possible. However, our mankind has produced a great number of other inventions since that time. Robots are one of them.
Nowadays people use 90% of robots for heavy, repetitive manufacturing work. These robots handle tasks that are difficult, dangerous or boring to human beings.
The most common manufacturing robot is the robotic arm. It typically consists of seven metal segments. Tiny motors or actuators put them into opera¬tion when a special computer gives them certain instructions.
An industrial robotic arm with six joints closely resembles a human arm - it has the equivalent of a shoulder, an elbow and a wrist. This type of robot has six degrees of freedom, i.e. it can turn in six different ways. A human arm, by comparison, has seven degrees of freedom. Your arm moves your hand from place to place. Similarly, the robotic arm moves an end effector from place to place. You can supply robotic arms with all sorts of end effectors, which will perform a certain task, for example it will grasp and carry different objects. Robotic hands often have built-in pressure sensors that tell the computer how hard the robot is gripping a particular object. That's why the robot doesn't drop or break whatever it's carrying. Robots do their work more efficiently than human beings because they are so precise. They always drill in the exactly the same place, and they always tighten bolts with the same amount of force, no mat¬ter how many hours they've been in operation.
Перевод
Когда инженеры изобрели паровой двигатель в 18-м веке, некоторые люди говорили, что все возможное уже изобретено. Тем не менее, наше человечество произвело большое количество других изобретений с того времени. Роботы являются одним из них.
В настоящее время люди используют 90% роботов для тяжелых, механических работ. Эти роботы выполняют задания, которые трудны, опасны или скучны для человека.
Наиболее распространенным является производство роботизированных манипуляторов. Они, как правило, состоят из семи металлических сегментов. Крошечные двигатели или приводы приводят их в действие, когда специальный компьютер дает им определенные
