Abstract

An automated guided vehicle (AGV) is an automation system which is a driverless vehicle, mostly used in several Flexible Manufacturing Systems (FMS) installations. The main item in this study is to make an AGV with the capability of adjusting the height of a conveyor platform attached on it. Software such as SOLIDWORK will be used in this purpose basically to design several options and to choose the best by following specific criteria and specifications. This study includes the integration of electrical, mechanical, and design for build and testing of the AGV including mechanisms such as sensors, vision camera (pixycam), conveyor and electric jack lifter to make it more flexible. Microcontrollers such as Arduino Uno and Arduino Mega have been studied, programmed and installed as the controller of the AGV. It has been designed in a way that can easily be disassembled or modified to become more efficient. For this project, several testings have been conducted to test and analyse the performance of the AGV. In this experiment, green colour which have marker size of 5cm x 5cm are selected for camera detection using Pixycam camera due to the effectiveness for camera to detect and prevent from unwanted colour compared to other colours. Besides, load testing of 30 kg (maximum) have been selected and tested in this experiment to observe the performance (time taken) of height adjustable for this AGV to move upward or move downward. Finally, line following testing have been conducted at a certain speed to move straight and to align the AGV conveyor height with the receiver conveyor’s height for loading and unloading process.
