- 8. Why PID over ‘if-else’ coding? The Idea was to create a robot which could figure out which path he should go himself regardless of the lighting conditions. Since the average “if-else” coded robots face critical situations when there is a change of ligh.The use of PID not only prevents that , but also makes the robot much more stable and reliable .The concept of PID is pretty straight forward , Instead of depending on the threshold value*,PID line follower robot creates the value himself on the go. So regardless of the situation the robot can run anywhere any time , without calibrating it again and again .That’s the beauty of PID. *A threshold value is a value , defined by users by calculating the value given by the IR sensors.
- 9. Performance The performance of the robot was truly amazing as this was the first time doing such work. It was an amazing experience and truly it was fun to work. Link: Line follower Robot Using PID
- 10. Conclusion • PID helps bot to be stable. • PID helps bot to turn smoothly. • PID code is smaller and efficient. • Even if it looses track , it can revert back to track. • PID is far better than if else coding. • PID uses integration , proportion, differentiation.
