Line follower robot

Abstract

This project is to create a robot that will follow a black line on white surface with microcontroller PIC16F877A to control the robot movements. This project is divided into two parts that electronic system and software. A Line Follower robot consist IR sensor that trail black line on white surface. The outputs from IR sensor become input to microcontroller for Line Follower Robot movements. Line Follower Robot can operate by using 9Volt battery for servo motor and four 1.5Volt AA batteries as input voltage for IR sensor circuit. The best IR sensor distance with reflections surface for Line Follower Robot are 1.0 centimeter because the sensitivity for IR sensor very good at this condition. Line Follower weight is 500 gram for complete system. The software that use to create the programming is MPLAB Integrated Development Environment because easier to use and its can run more then one type of programming as ASM language and C++ language.
