CHAPTER I INTRODUCTION

1.1 Project Overview

Nowadays wireless technology is so important in our daily life to make human life better and simpler. Bluetooth PAN Technology is the one of them where, the usage of this technology become popular and useful to many application such as Bluetooth headset where we remove the wire of headset and transfer the audio in wireless. Almost every cell phone that we use nowadays is equipped with Bluetooth device and every day we not miss to bring this phone in the pocket because it was become a part of our daily life. In order to make our life is simpler; we need something that can do more in just one device. Due to this idea, this project will use Personal Digital Assistance, PDA as an input to control the wheelchair and other home appliances. Operation and the movement of this robot will be controlled by using PDA and it also can be controlled by using computer. Visual Basic.NET, VB.NET software is used in this project as an interface in PDAPC. Then the user input from this interface will be transmitted in wireless using Bluetooth and the wheelchair will be act as a receiver. PIC microcontroller is used in this project as a brain of the wheelchair. It will control the motor operation and other devices such as horn and etc. IP camera also it equipped on this wheelchair. With this camera, this wheelchair can be monitor trough the PDAPC directly. Figure 1.1: HTC P3600i with Samsung 500MHz Processor and Windows Mobile 6.0

1.2 Project Objectives

The main objectives of conducting this project included: i. To design a user friendly controller system via PDASmartphone for the maneuver robot‟s platform. ii. To design a robot platform that can be used for many purposes. iii. Help human life be more convenient. iv. To use Bluetooth PAN Technology as a wireless connection medium.

1.3 Problem Statement

Disabled people especially paralyzed on their leg, as we know they have a difficulty on their movement. For example, they have a difficulty when they want to walk, move to other place, stand and any task that they need to use their leg. Because of these issues, wheelchair has been invented in order to facilitate this people. On available market, there are two type of wheelchair that commonly we will get. First, normal wheelchair that use human power for the movement and second is motorized wheelchair. The conventional motorized wheelchair used electrical power to power up the motor for the wheelchair movement and it used joystick that placed on a wheelchair as a input to control the direction of the wheelchair movement. Figure 1.2: A, Normal Wheelchair and B, Motorized Wheelchair This wheelchair already helps a lot of disable people in terms of facilitate for their movement. However, this wheelchair has some limitations. The issues are:  Conventional motorized wheelchair cannot be control remotely.  This people still needs others people help. Example: o To keep the wheelchair when not in use because it cannot be remotely control. o To control another home electrical appliance, lamp, fan and etc. using switch on the wheelchair.  High cost for only one function where only can control the wheelchair‟s movements. By investing this project, it will cost a benefit to this group such as:  It can be control remotely either using PDAPC.  Will help this group to having a less banking on support-from other people with the PDA that can control the wheelchair and others electrical appliance.  Cost effectively for two function where can control the movement of wheelchair and other electrical appliance using PDAPC.
