Build Your Own Microcontroller Based PID Control Line Follower Robot (LFR) – Second Part

August 30, 2009 by rwb, under Robotics.

One of the interesting parts in building the Line Follower Robot is; you could start it with a very simple version by using just two transistors with the LED and LDR for sensor (Build Your Own Transistor Based Mobile Line Follower Robot - First Part) and enhance it to the programmable version that use microcontroller as the brain for controlling the robot. The reason of using the microcontroller for the Line Follower Robot is we need to make more robust, reliable and flexible robot which you could not have it from the discrete electronics component robot without changing most of the electronic circuit design.
