A robot is a machine designed to perform tasks automatically, often mimicking human actions. They can be programmed to carry out specific functions, such as assembling products in factories or assisting in surgeries. Robots come in various shapes and sizes, from small robotic vacuum cleaners to large industrial machines. Many robots are equipped with sensors and artificial intelligence, allowing them to interact with their environment. For example, a robotic arm can pick up and move objects, while a humanoid robot may walk and talk like a person. As technology advances, robots are becoming more common in our daily lives, enhancing efficiency and safety.
