A robot is a machine designed to carry out tasks automatically, often with a level of autonomy or control that mimics human actions or intelligence. Robots can be programmed to perform a wide range of functions, from simple repetitive tasks to complex problem-solving operations. They are typically made up of mechanical components (like motors, joints, and sensors), electronic systems (such as processors and control units), and software that directs their behavior.

Robots come in many forms—some look humanoid, while others resemble arms, vehicles, or drones. They are widely used in industries like manufacturing, healthcare, space exploration, agriculture, and even in homes as personal assistants or cleaners. As technology advances, robots are becoming smarter, more adaptable, and increasingly capable of working alongside humans in everyday environments.
