Nowadays there is lots of technology based on robotic which has been invented by human intelligence. Therefore, it is not possible for robot to be controlled by sensor technology. This dissertation project objective is to create an autonomous luggage robot model system that can operate with wheelchair model using optical sensor. Autonomous luggage robot is followed a black line tracking path that was designed at the back of the wheelchair model. The product design method has been used to accomplish this project where it focused on hardware devices and assembly language programming. The most important devices used in hardware devices are consist of AT89S52 microcontroller, H-bridge motor driver and Optical Photomicrosensor. This AT89S52 microcontroller is required to control the input from Optical Photomicrosensor and perform the output to H-bridge motor driver for robot movement operation. The robot operation algorithm was designed by the aid of the 8051 microcontroller assembly language programming, in which, the robot machine and the assembly language source codes have been programmed into the AT89S52 microcontroller chips. The objectives result has been archived which the robot can follow the wheelchair model for turn left, turn right and stop operations.
