Because they are more accurate, more reliable and faster than when people run an assembly line.
They can control robotic arms but also maintain full machines.

computers are used in economics for calculating specific formulas through programs created to meet the needs of economists. They probably are also used to track industries and markets over seas.
many industries are being created mainly in the web design industries
The answer is industries that function as repairing the computers accesories.
I worked for in Robotics for three years. The robotic arms were used in many industries including automobile manufacture. Ie welding of sub frames and paint spraying.
Robotic ants, about the size of a sugar cube are used by scientists in studies of social and swarm behavior.
The reason is because computers these days are getting smarter and smarter, they do a lot of the jobs which ordinary people used to do. this is why there are less industries around now.
That is not a simple question to answer. A robotic device can be controlled by many different types of computers, anything from a small imbedded processor to a large mainframe computer. Knowing how to program the robotic device requires that you know how to cause the computer to set the appropriate output that is connected to the individual circuits of the robot. Many computers can be programmed using what is referred to as a "higher level language", and some robotic devices even have programs running that allow you to make simple robotic commands to cause the computer to set the appropriate outputs. There is no simple way to tell you how to program a robotic device, since they are all different.

A robotic device can do whatever it's designed to do. There are robotic devices that are designed to paint vehicles in an automobile manufacturing facility, and those robotic devices simply paint vehicles. There are robotic devices that are used to cut metal shapes and others that are designed to cut wooden shapes. There are robotic devices that are used to laser etch, and others that are designed to carve shapes. So far, there are no true "general purpose" robotic devices.
Crucial US industries need to be protected from competition because they contribute heavily to the country's GDP. Computers and steel industries also employ many people in the USA.
