What are modern robots used for?, Today, robots are part of many aspects of industry, medicine, science, space exploration, construction, food packaging, and even performing surgical operations. The newest robots can move, speak, walk, run, or fly, and can work independently from humans. They possess "intelligence" that enables them to make independent decisions and interact with people. As they become more adaptable, they can be used for everything from military purposes to elderly care., What are the benefits and dangers of robots, Some people believe that robots have many advantages over humans.

They started to become smart and fast, capable of being programmed to perform a wide range of functions. The first digitally controlled and programmable robot, called Unimate, was invented in 1954. Unimate was used in the US for assembling automotive components. This was the first significant step toward the automation of automobile production..
