What Is a Robot?

Before learning how to build a robot, it is important to understand what a robot actually is.

A robot is a machine designed to perform tasks automatically or semi-automatically. Most robots contain three key elements:

• A structure or body
• Sensors to gather information
• A control system that makes decisions

Some robots are simple and perform one task repeatedly. Others use artificial intelligence and can learn from their environment.

Examples include:

• Robot vacuum cleaners
• Industrial robotic arms
• Delivery robots
• Drones
• Humanoid robots
• Agricultural robots
• Medical robots

A robot does not have to look like a human. Any machine that senses, processes information, and acts can be considered a robot.
