HANDS-ON STEAM PROJECT
Line Follower Robot
Use infrared sensors to follow a contrasting track.
Instructions and Learning Resources
Project idea
Follow a black line on a white surface using reflectance sensors and simple steering decisions.
Key parts
IR sensor pair or array, wheels, motor driver, microcontroller, chassis and battery.
Build outline
- Assemble the chassis.
- Test sensor response over the track.
- Connect a motor driver.
- Implement left/right correction.
Use safe low-voltage batteries and check motor-driver current ratings.
