Essential Robot Components
Every robot is built from fundamental components. Let's explore each one!
1. Microcontrollers (The Brain)
The microcontroller is the robot's brain. Popular options:
- Arduino: Beginner-friendly, C++ programming
- Raspberry Pi: More powerful, runs Linux, Python
- ESP32: WiFi/Bluetooth capable, IoT projects
2. Sensors (The Senses)
| Sensor Type | Purpose | Example Use |
|---|---|---|
| Ultrasonic | Distance measurement | Obstacle avoidance |
| IR Sensor | Line detection, proximity | Line-following robots |
| Camera | Vision, image recognition | Object detection |
| IMU (Accelerometer + Gyro) | Motion, orientation | Balance, navigation |
| Temperature | Heat detection | Fire detection robots |
3. Actuators (The Muscles)
- DC Motors: Continuous rotation, wheels
- Servo Motors: Precise angle control, robotic arms
- Stepper Motors: Accurate positioning, 3D printers
4. Power Supply
Robots need power! Common options:
- AA/AAA batteries (6V-9V)
- LiPo batteries (7.4V, 11.1V)
- USB power banks (5V)
💡 Tip: Always use a motor driver (like L298N) between microcontroller and motors to prevent damage!
