Abstract: “A food and beverages serving robot using fuzzy logic technique is presented in this paper. The utilisation of fuzzy logic technique\'s objective is to improve the performances and behaviors of these service robot in performing a line following technique to go to a group of workers in a targeted cubical office. A PIC16F877A is used as a controller and RF 315MHz transmitter and receiver are used to communicate between the user and the controller. The program was created by using the MPLAB IDE software. By using an optimal setting of Pulse Width Modulation (PWM), the performances of the robot were analyzed by recording the time and speed taken by the robot to complete the task with and without the utilisation of fuzzy logic. Both of the data is compared and discussed. The results shows that the line follower robot can reach the destination with minimum of time and smoothly with the fuzzy logic approach.”
