Line Following

  • Single Sensor (odp / pdf)
    • 2-States, 3-States, and 5-States algorithm
    • Proportional controls
  • Double Sensors (odp / pdf)
    • Use the difference method to line follow with two sensors
  • Obstacles Avoidance (odp / pdf)
    • Obstacles along the line can come in different shapes, sizes, and position. Learn how to navigate around them safely.

Wall Following

Wall following uses the same control techniques as line following, but instead of reflected light intensity, you’ll use the side facing ultrasonic sensor distance as input. In order to be stable, the sensor needs to be in front of the wheels.
