CHAPTER I

INTRODUCTION

1.1 Introduction

Interface communication is used to communicate between Remotely Operated Vehicle (ROV) and matrix laboratory (MATLAB) computer for data transmitting and data receiving purpose. Data from ROV is transmitted to or received from MATLAB via interface communication during the operation. ROV and MATLAB response and take action after data is successful received through interface communication.

However, due to the high cost and multipurpose used of the interface above, those interfaces are not suitable for low cost interface design. Low cost interface only required transfer and receive data between ROV and MATLAB. Therefore, interface such as serial port connection, parallel port connection and Universal Serial Bus - Recommended Standard 232 (USB-RS232) converter cable are compared based on the cost, data transfer rate, size and quality of cable length. Low cost interface, faster data transfer rate, stable and less noise are suitable for low cost ROV design.

Several types of interface such as serial port connection, parallel port connection and USB-RS232 converter port are compared based on the cost, data transfer rate, size and quality of cable length. Low cost interface, faster data transfer rate, stable and less noise are suitable for low cost ROV design. The quality and performance of the USB-RS232 is tested using loopback method. Cable interruption and fast data transfer are tested and observed using Test and Measurement Tool (TMTOOL) and Hyperterminal methods. Voltage of cable is measured and compared before and after cable is disturbed and shakes, and overload data transfer during data transferring. At the initial stage, potentiometer is used to transmit data to MATLAB, which act as a sensor transmit data to MATLAB by adjusting the resistance from 0kΩ to 20kΩ via pin 25 of PIC16F877A. While receive data at pin 26 after MATLAB send data to PIC and light on the LEDs. Besides that, Graphical User Interface (GUI) provides a very convenient tool to control the ROV and to display data of an ROV. Various tasks that can be performed by the GUI include display condition of ROV such as speed of thruster, accelerometer and sonar sensor.

1.2 Objectives

The main purposed of this project are to design an interface for MATLAB and ROV System. Therefore, the objectives as below should be achieved.

i. To identify the suitable low cost interface communication between ROV and MATLAB.

1.3 Problem Statement

Generally, an autonomous underwater vehicle (ROV) is a robot which travels underwater with many types of sensors and propulsion system with unman control. ROV passed the information received from sensors and pass it on the computer to analyze this information. The communication between the ROV and computer is achieved via interface communication.

However, for existing ROV project, the cost for conventional interface communication such as interface card and communication devices are very expensive to perform underwater operations. Many small and medium type companies or researchers are not able to afford the high technology interface communication cost. Installation sensors for orientation control of ROV such as gyrosensor or inertial measurement unit (IMU) is very expensive and unsuitable for research and study purpose. Besides that, many research centers use low quality interface communication for researching and exploring, data transmission will be affected by environmental factor such as noise and obstacles influence their findings.

For this situation, USB-RS232 used as low cost interface communication between MATLAB and ROV, which able to transmit and receive data in real time orientation control. Accelerometer sensor used as stability sensor to perform the stability of ROV during real time orientation control. MATLAB GUI is designed to display and save the instant data from accelerometer to control the speed of motor.

1.4 Scope of Work

detect the balancing and stabilizing of orientation ROV. MATLAB GUI displays the current data of accelerometer and monitors speed of motors underwater.

1.5 Thesis Structure

It consists of six chapters. Following is a chapter-by-chapter description of information in this thesis.

Chapter 1 gives reader a basic introduction to how the idea of this project generated. The chapter contains introduction, objective of the project, problem statement, scopes of work, brief methodology, and report structure.

Chapter 2 is a literature review on theoretical concepts applied in this project. The chapter concludes the background study of serial, USB-RS232 converter and parallel cable. Besides that, this chapter also explains maximum cable lengths for interface, what is MATLAB, what is Test and Measurement Tool, what is Hyperterminal and application of others component such as PIC16F877A, Accelerometer and Gyrosensor. Then, why choose the specific interface, MATLAB, Hyperterminal and related components.

Chapter 3 introduces the methodology of the project. The chapter contains the flow chart which explains the overall method taken along the project carry out. Besides that, this chapter also introduces the construction of the project, which involves hardware development and software development. Basically, the hardware development for the project concludes with ROV accelerometer sensor, thruster, and block diagram design. Besides, the software development of project will discuss what graphical programming is, how to use the MATLAB and C programming, and how to implement it on this project.
