Nowadays, Robot is used in the factories across the world because the robots become more efficient and precise than the humans. Advantages of Robots such as: Robots can work many time without any salary and food, do not require to sleep or take breaks, can not tremble or shake as the human hands do and can do the jobs that the people are unwilling to do. Disadvantage of Robots include: Robot needs a supply of power, can take the place of many humans in the factories, can store large amounts of data but the storage, access, and retrieval is not as effective as the human brain. This limits how the robots can help and interact with people.
