What is Robotics - Complete Guide

What is Robotics?

Robotics is the interdisciplinary field of designing, building, and programming robots — machines that sense their environment, make decisions, and perform physical tasks. It combines mechanical engineering, electronics, and computer science.

The Main Components of a Robot

Component	Role
Sensors	Perceive environment (camera, lidar)
Actuators	Create movement (motors)
Controller	The "brain" (microcontroller/computer)
Power supply	Battery/energy

Types of Robots

• Industrial — assembly line arms.
• Service — vacuum cleaners, delivery robots.
• Humanoid — human-like robots.
• Autonomous — self-driving cars, drones.

How Robots Work

Sense (sensors) → Think (controller/AI) → Act (actuators)
// This loop repeats continuously

Robotics + AI

Modern robots use AI and machine learning for vision, navigation, and decision-making.

FAQs
