This collaboration proves that robots are designed to enhance human capabilities, not erase them.

2. Core Components of Robotics

To understand robotics, it’s essential to look beyond the surface and explore the core building blocks that make a robot function. Every robot-whether it’s a factory arm, a self-driving car, or a space rover-is powered by a blend of hardware and software working in harmony. Think of it like this: Robotics = Hardware (Body) + Software (Brain) + Power (Energy) + Sensors (Senses).

The Fundamental Components of Robotics

1. Mechanical Structure (The Body)

Robots need a physical frame or structure-this could be wheels, legs, or arms depending on their purpose.
Built with materials like aluminum, carbon fiber, or steel for durability.
Determines the strength, speed, and flexibility of the robot.

2. Sensors (The Senses)

Sensors act as the eyes, ears, and touch of a robot.
Common sensors include:
- Cameras & Vision Sensors → for object recognition.
- Infrared & Ultrasonic Sensors → for obstacle detection.
