A robot is a machine designed to perform tasks automatically, often replicating human or animal actions. Robots can be physical (like industrial arms, humanoid robots, or autonomous vehicles) or virtual (like AI chatbots and software bots). They can be controlled by a human, follow pre-programmed instructions, or operate autonomously using sensors and artificial intelligence.
Types of Robots:
- Industrial Robots – Used in manufacturing (e.g., car assembly lines).
- Service Robots – Assist humans (e.g., vacuum robots, medical robots).
- Humanoid Robots – Resemble humans in form and function (e.g., Sophia the robot).
- Autonomous Robots – Operate independently using AI (e.g., self-driving cars).
- Military & Space Robots – Used for defense, exploration, and reconnaissance (e.g., drones, Mars rovers).
