A robot is a mechanical device that is designed to perform a variety of tasks automatically or with minimal human intervention. Robots can be programmed to perform a wide range of activities, from manufacturing and assembly line work to exploration of hazardous environments or space missions. They are typically composed of a body, sensors, actuators, and a control system, which allows them to interact with their environment and perform their tasks. Robots can be designed to perform tasks that are dangerous or difficult for humans to perform, as well as to increase efficiency and productivity in a variety of industries.
