I finally got a chance to record the line follower in action. I had to readjust some numbers in the code for it to be able to work. The floor here is different from where I was initially testing the line follower. So, I got different readings from the infrared detectors. But here's a quick video of the line follower. There was a part where the line follower seems to stop but it was because a piece of the tape was sticking out. So it got in the way since the robot has a low clearance to the ground.
