Sensors for robots
Let robots perceive the world.
📖 Key ideas
- Distance: ultrasonic, IR, LiDAR, time-of-flight.
- Orientation and motion: IMU (accelerometer + gyroscope).
- Line following: IR reflectance sensors.
- Vision: cameras with computer vision.
- Wheel encoders measure distance travelled.
💡 Real-life example: Sensors are a robot's eyes, ears and inner ear for balance.
