3. Today’s engineer has no need for the skill of precise manual calculation of complex structures, but he
should know the principal laws of construction mechanics, sense the ‘play’ of forces in a structure, have
knowledge of the principles governing the operation of various types of constructional system, and be able to
evaluate the results of calculation.

A MACHINE SHOULD WORK, A MAN THINK
1. The robots of our time resemble humans very little. According to specialists, the main thing for them is
not to look like people, but to do their work for them. Factories which are equipped with automatic machine
tools, transfer lines and management information systems place a lot of hope in them. Automation sought out
areas where a robot can operate as well as a person but where people don’t like to work. In other words, man
has created the robot so as not to become a robot himself.
2. The first generation of robots appeared in the 60s and they were complex and capricious in maintenance.
They could perform operations of the type "take off – put on" or "pick up – bring". They could pick up items
only from definite positions determined by a rigid programme. Today, to avoid errors, robots are supplied with
vision (TV camera) and hearing (microphone). They can perform more complex productions – painting, solder-
ing, welding and assembly work.
3. A more complex task lies ahead – to remove people completely from production areas where there are
harmful fumes, excessively high or low temperatures and pressure. People should not work in conditions that
are dangerous. Let the robots replace them there – and the sooner, the better. Generally speaking a single robot
