Project Summary

A regular person will never truly comprehend what it is like to live with any form of impairment. Those who have never spent a day in a wheelchair, or tried to eat their lunch without using their hands will never understand how important it is to be able to walk, see, and use their hands spontaneously and independently. They do not even need to have a long-term crippling ailment or sickness; just a few months with a shattered, leg or arm is enough to show how executing ordinary tasks that were formerly considered normal and automatic become tough and hard.

People with a variety of physically disabling conditions, such as cerebral palsy, quadriplegia, hemiplegia, muscular dystrophy, or high spinal cord lesions, use electric powered wheelchairs. Estimates of the number of people living with disabilities in Pakistan range from 3.3 million to 27 million. Physically challenged persons have been seen using assistance devices such as crutches, artificial limbs, and manual wheelchairs for their day-to-day movements in the past.

Because most manual wheelchairs have the difficulty that the rider must use physical force to spin the wheels in the direction he or she wants to go. It can induce muscular and joint pain, degeneration, repetitive stress injury, and carpal tunnel syndrome, all of which can lead to secondary damage or impairment. We met Muhammad Tayyab Saqi, a student who was dealing with difficulties and hardships in his daily life. He began to have trouble walking after contracting typhoid as a teenager. He was in his second year when he was involved in an accident. The sink in the washroom toppled on his foot, damaging his thumb tendon. His wounded limb was getting impacted day by day as a result of his saphenous vein not functioning properly. The problem worsened, and he was forced to use a wheelchair. He could not even walk without assistance. We decided to work for disabled persons so that they could move about independently because of him. As a result, the proposed prototype will give "differently-abled" people (handicapped, quadriplegic, hemiplegic, paralyzed, and spinal cord injury) the freedom to move around and perform things just like anybody else. Our prototype will enable the user to recline in space (rotational backrest), elevate (Up/down of seat), and stand (whole structure is in standing position).

Project Objectives

• To provide people with disabilities and older adults enhanced assistance in mobility.
•  To equip them with functional mobility for instance; doing house chores etc. 
• To provide convenience and comfort for them in their daily life.
• To help them in maintaining their balance and posture.
• To increase their participation in social life.
• To improve their quality and increase in productivity.

Project Implementation Method

1. All technical requirements will be evaluated in the concept paper at first. Providing an electric wheelchair with a set of general rules and estimates.
2. Conduct a literature review to obtain a better understanding of the area.
3. In order to have a realistic and adequate design, software/hardware compatibility to provide control to the wheelchair will also be considered at the outset.
4. In a simulation environment, 3D models of the electric wheelchair will be developed and evaluated.
5. The basic structure will be changed to accommodate the DC motor and batteries, as per the design specifications.
6. The wheelchair's functionality will be assessed at this point in order to proceed.
7. Software implementations will be built once a functioning prototype multi-degree of freedom electric wheelchair is achieved.
8. This will entail the employment of microcontrollers and software to give the wheelchair a brain.
9. Inventing and constructing electric wheelchair implements.
10. Make sure everything is in place and working together.

Benefits of the Project

• The user will be able to relax in a way that is not possible with traditional seats.
• Assisting a patient with their body waste is significantly easier when they are seated in a reclined or tilted position.
• Users would be able to easily raise their seat height rather than straining to reach the top cabins or open a refrigerator easily.
• An elevation mechanism makes it considerably easier to transfer from a wheelchair to other surfaces, such as beds and chairs.
• Another benefit is being able to raise a wheelchair to other people's eye level in a social context can boost a wheelchair user's self-confidence and social skills significantly.
• The spine is stabilized in a standing position, and pressure on the system is lessened, allowing oxygen and blood to move more freely. Breathing becomes less taxing when overall respiratory function improves.
• Overall posture is improved.
• Little to no pressure sores which are still a great problem in manual and electric wheelchair till to date.

Technical Details of Final Deliverable

1- A working prototype which will fully demonstrate the true purpose and need of multi degree of freedom in an electric wheelchair.

2- Market research and advanced Analytics.

3- 3D Cad designs and analysis.

4- Efficient electrical system to drive the wheelchair for constantly six hours on a single full battery charge.

5- The wheelchair will control its reclining, elevating and standing motion, with the help of actuators realized by motors powered by batteries.
