PID line follower with 5" robot chassis

Posted by Claire on 18 April 2014

This PID line follower, originally featured in this Let’s Make Robots post by user Enigmerald, uses our 5" Robot Chassis along with 30:1 MP micro metal gearmotors, extended brackets, and our 42×19 mm wheels. Our QTR-8RC Reflectance Sensor Array is used to sense the line and our TB6612FNG carrier, along with an Arduino-compatible controller, is used to control the motors. A diagram of how everything is connected and the code for the robot are available in Enigmerald’s post. The post also has a link to a basic tutorial on PID tuning using the QTR array.


I would like to know how did you implement PID Algorithm? If possible send the arduino code you use
Hello, vinay.

The maker of that robot, Enigmerald, links to a tutorial about PID for line following that they wrote.
