An industrial robot can often do this repetitive work more efficiently than human beings because they are so precise. A robot always drills in the exactly the same place, and always tightens bolts with the same amount of force, no matter how many hours it’s been working. Many industrial robots work in auto assembly lines, putting cars together. An industrial robot is very strong, lifting large car pieces easily, and never get tired. Even though an industrial robot is capable of great strength, it is also capable of performing very delicate operations as well. This makes them very useful in the computer industry which requires an incredibly precise hand to put together a tiny microchip.
