Cost: The most obvious advantage of robots is their cost. Robots are cheaper than most human counterparts, and their costs are still decreasing. Abilities: Robotic abilities, what robots can do, are now extremely vast and growing. Productivity: Robots do not tire and can work very long hours without service or maintenance. As a result, robots can be significantly more productive than people.
Disadvantages:
Jobs: In my opinion, the biggest issue with using robots is the huge loss of jobs for people. Basically, robots have eradicated a wide range of middle class jobs in several industries, such as car manufacturing. Limited Functionality: Robots are very good at doing perfectly defined jobs, however robots typically do not handle the unexpected as well as people do. Lack of Intelligence: Since robots are not intelligent or sentient, robots can never improve the results of their jobs outside of their predefined programming. In other words, robots do not think. At least, not yet.
