Abstract

This project is to develop a Simultaneous Localization And Mapping (SLAM) for

mobile robot car controlled by using a "tiny computer" called Raspberry Pi as the main

control board. The purpose of this project is to resolve the old line-following method for

automatic guided vehicle or mobile robot car that utilized by factory for transportation

purpose. Since old line-following method has been encountered some issues that caused

the mobile robot car unsuccessful to deliver materials from starting point to destination.

The major issue is line such as physical white line along predefined path on floor

eliminating gradually due to problem of tear and wear. Thus, mobile robot car unable to

detect the line on floor to travel. Therefore, by using new technique called Quick Response

code (QR code) able to resolve the problem of line-following method. It is to replace the

line along the path on floor with QR code. QR code is the trademark of a type of matrix

barcode or two-dimensional barcode that able to store the data and fast readability. The

mobile robot car compatible with the Raspberry Pi Camera can captures the image

containing QR code and decodes it quickly in order to retrieve the data within it. The data

stored within QR code is location point in coordinate form (x, y). Each QR code stored one

location point. QR code symbols is placed on floor with same distance with each other. So

that mobile robot car has to travel a certain distance to capture QR code and decode, then

continue to move until it reach at destination. While decoding it, monitoring system on web

also keep track of position by showing the location of mobile robot car. The monitoring

system can let user clearly to determine position of mobile robot car either on track or stuck

at any point along the pathway. Lastly, the QR code places on the floor not only reduces

the problem of tear and wear as compared to line, but also the fast readability of QR code

that made it became more reliable. Thus, QR code is a great solution to replace the old line-

following method and suitable to implement it on this project.
