Robots are being used today to do tasks that are too dirty, dangerous, difficult, repetitive or dull for humans. Most them are industrial robots used in factories. Since the late 1950s, robots have been used for the jobs in factories that involve repeating the same action over and over again. People get tired or bored in such situations, but robots do not, and it's nothing for them to do the same thing thousands of times a day.
Robots are also used in cleaning up pollution, exploring space, carrying out search and rescue operation, and getting rid of bombs. Bomb robots have an arm that lifts the bombs and puts them into a safe place. In places that have been polluted by germs, chemicals, or radioactivity, robots are extremely useful because they can where humans cannot go. In the early 21st century, domestic robots also entered our everyday life with the success of the robotic pet dog released by a well-known company.
Several manufacturers have contributed to this trend of domestic robots by producing robotic vacuum cleaners. Robots will doubtless become even more important in society as we become better at making them. It is said that they will soon become widespread in hospitals and perform delicate operations that a human cannot. Traditionally, dogs have been called "man's best friend" because of their important role in human lives. Robots may soon take the place of the dog as our closeat companions.
