Robotics for Kids
Learn Robotics Step by Step
1. What is a Robot?
A robot is a machine that can perform tasks with instructions from humans.
2. History of Robots
Before robots, humans did all work. Now robots help humans in factories, hospitals, and space missions.
3. Parts of a Robot
Main parts of a robot:
- Body (Frame)
- Brain (Controller)
- Sensors (Eyes/Ears)
- Motors (Hands/Legs)
- Power (Battery)
4. Sensors
Sensors help robots feel the world. Types include:
- Light sensor 💡
- Distance sensor 📏
- Touch sensor ✋
- Sound sensor 🔊
5. Actuators (Motors)
Actuators help robots move. Types: DC Motor, Servo Motor, Wheels.
6. Programming & Coding
Programming is giving instructions to a robot. Example:
2. Turn left
3. Stop
Use block coding: Scratch, Blockly, Micro:bit
7. Simple Robot Projects
Project 2: Moving Robot (Left / Right)
Project 3: Obstacle Avoid Robot (Concept)
8. Robot Safety Rules
- No water near robots
- No short circuits
- Adult supervision required
