Week 3 - DRAW THE BLOCK DIAGRAM

This week, to allow you to understand how we will function electronic wheelchair, we have created a block diagram ,

Week 2 - PIC MICROCONTROLLER

PIC microcontrollers ( Programmable Interface Controllers), are electronic circuits that can be programmed to carry out a vast range of tasks. They can be programmed to be timers or to control a production line and much more. They are found in most electronic devices such as alarm systems, computer control systems, phones, in fact almost any electronic device.PIC Microcontrollers are relatively cheap and can be bought as pre-built circuits or as kits that can be assembled by the user

You will need a computer to run software, such as MPLAB, allowing you to program a PIC microcontroller circuit. A fairly cheap, low specification computer should run the software with ease. The computer will need a serial port or a USB port. This is used to connect the computer to the microcontroller circuit.

                                                                                                                                  

Software such as, MPLAB can be downloaded for free. It can be used to program microcontroller circuits. It allows the programmer to simulate the program, before downloading it to a PIC microcontroller IC (Integrated Circuit). Simulating the program on screen, allows the programmer to correct faults and to change the program. This means that a program can be written quite quickly, with fewer mistakes.

                                   

A USB lead connects the computer to the programmable circuit, allowing the transfer of the program to the PIC microcontroller IC.

               

 When the program has been simulated and works, it is downloaded to the PIC microcontroller circuit. The USB lead can be disconnected and the microcontroller circuit can be used independently.

Week 1 - FYP Briefing

First week of new semester. FYP briefing for Diploma  is held in TTL2.
For the first week, I attended a talk located at TTL about the final year project that was conducted by Mr. Zubir bin Suboh and Mr. Samsol. 

The talk is about the requirements and guidelines of the final year project which the students must provide a blog of the their projects' progression and for the lecturers' evaluation. 

Besides, the lecturer also stated that the students must provide a report regarding their final project as one of their assessments for the final year project. Candidates also must provide a presentation at the end of the progression about their project details. 

OBJECTIVE

Everything we do should have an objective that would benefit either to themselves or society. For us, the goal is to modernize usage of wheechair parallel to the modern world. Other than that, we also want to create a tool to help people who cannot walk, electronic wheelchair also can help those who have no strength either in the upper body and lower body. And most importantly, we want to build a tool that not only helps people but the price is affordable for all segments of society.

• To modernize the use of a wheelchair by using PIC microcontroller
• Give mobility to people who cannot walk
• Provide facilities for people who have no either upper body strength or lower body strength

PROBLEM STATEMENT

The problem for wheelchair users is that they have to push the wheel manually using their hands to move and this will pose a problem for the elderly or those who are paralyzed in the upper body. The problems faced by wheelchair users is when to travel long distances, they will feel tired and fatigued to push their wheelchairs during the journey. Furthermore manual wheelchair difficult to move and its users will experience difficulties in moving.

• Manual wheelchair is difficult to control the movement.
• Normal wheelchair need to use human energy to move it and it will give trouble to the user that have no strength.

INTRODUCTION

According to Wheelchairs, Wheelchairs give mobility to people who cannot walk. Knowing basic information about the types, accessibility, leans and safe use of wheelchairs is important . Many prototypes of wheelchairs were developed in the research laboratories. Thus, EPW make up a significant portion of the mobility assistive devices in use today for the motor disabled and patients in recovery. While standard wheelchairs are mainly used by those who have the necessary upper-body strength to propel and manoeuvre it,EPW are destined for those who cannot: people with excessivebody weight, poor health, weak upper limbs, and those longtime living with the disability.And our main goal is to build affordable electronic wheelchair to everyone.
