Robots come in many forms and serve various purposes. Some robots travel through dangerous places like space, the bottom of the ocean, or inside volcanoes to do work that is impossible or unsafe for humans. Other robots work in factories performing repetitive tasks that are dull, dirty, or dangerous for people. Many industrial robots are used for assembly line work in automotive plants. Robots can operate 24/7 without breaks and perform tasks quickly, consistently, and accurately. While robots have advantages, they also present challenges as they may replace human jobs and require maintenance and energy to function.
