What is a robot?

Definition
A robot is a programmable mechanical device that can perform tasks and interact with its environment, without the help of human interaction. Robotics is the science and technology behind the design, manufacture, and application of robots.
Robots can be operated by remote control (known as teleoperated robots), automatically by themselves (known as autonomous robots), or a combination of teleoperated and autonomous operation (known as hybrid robots). Robots have become more popular over time because they are capable of performing very repetitive tasks or very dangerous tasks instead of humans.
What do robots do?
Most robots today are used to perform repetitive actions or jobs that are considered too dangerous for humans. A robot is ideal for getting into a building that has a possible bomb. Robots are also used in factories to build things like cars, chocolate bars, and electronics. Robots are now used in medicine, for military tactics, to find objects underwater, and to explore other planets. Robotic technology has helped people who have lost arms or legs. Robots are a great tool to help humanity.
What are robots for?
The reason robots are used is that they are often cheaper to use over humans, easier for robots to do some jobs, and sometimes the only possible way to do some tasks! Robots can explore inside gas tanks, inside volcanoes, travel across the surface of Mars, or other places too dangerous for humans to go where extreme temperatures or polluted environments exist.
Robots can also drill, they can weld, they can paint, they can handle hazardous materials, and in some situations, robots are much more precise than humans, which can reduce production costs, errors, or hazards. Robots never get sick, they don’t need sleep, they don’t need food, they don’t need to take a day off, and best of all, they never complain! There are many benefits to using robots.
