VARIANT 3.
1. Read and translate the text.
Although the development of robots seems a very mode
idea, the principles behind this new technology were known thousands of years ago. Even ancient Greeks and Romans used mechanical cogs and gears which are now an essential part of robot technology. In the Middle Ages there was a real breakthrough in the development of robot engineering. At that time many types of mechanical devices appeared. At the end of the 17th century engineers already knew about most of the mechanical components that make up a mode
robot.
Throughout history inventors have produced a variety of seemingly magical mechanical devices capable of quite life-like actions. These devices were not programmable, they were simply per¬forming a set of operations. Different scientists and engineers have applied many advances in this field since that time.
Today’s robot is a very complex structure. A metal or plastic frame serves for a skeleton, and a variety of actuators provide muscle power. But the new humanoids are not just bodies, they are also sophisticated sensing machines with cameras, microphones, even specific sensors that imitate the sense of touch. And then there are the brains. Nowadays scientists haven’t yet created such a robot that can think. But who knows, maybe in the future it will not only resemble a human being in appearance but will also have the capaci¬ty to think and feel.
