Design and Fabrication of Head Tilt Controlled Wheelchair for Disabled

Abstract

The quantity of crippled people is expanding consistently. Versatility helps are valuable for patients for transportation and are situation for strolling particularly in indoor and outside climate. Moving the patients from wheelchair to cot or to the clinical bed is generally an issue for the chaperon or assistant. Understanding the different issues with respect to the versatility gear and presenting a superior plan will be a resource for the clinical field and assistance for impaired people. There is a requirement for a wheelchair cum cot to work with the debilitated patient\'s portability and to give an original clinical hardware to use in the Indian emergency clinics. Here we are fostering a framework which is equipped for moving different positions (Seat, Semi-Seat and Cot) physically. These positions can be accomplished by a lead screw associated with a pivot joint. Lead Screw makes an interpretation of transforming movement into direct movement. Likewise, the level of the cot can be changed utilizing a fastener system physically. It is put on a level plane which pushes against a switch which lifts the primary arm. And furthermore, there is a cover on seat which can be opened to wipe out human waste. This is an expense lessening project which assists fundamentally deadened patients with doing their everyday things.

Introduction

I. INTRODUCTION

The different sorts of wheelchairs are manual wheelchairs, electric-controlled wheelchairs and game wheelchairs. An essential standard manual wheelchair consolidates a seat and back, two little front (caster) haggles huge wheels, one on each side, and a stool. Wheelchairs are much of the time minor departure from this essential plan, yet there are many kinds of wheelchairs, and they are frequently exceptionally tweaked for the singular client's requirements. The seat size (width and profundity), seat-to floor level, ottomans/leg rests, front caster outriggers, movable backrests, controls, and numerous different elements can be modified on, or added to, numerous essential models, while certain clients, frequently those with specific requirements, may have wheelchairs exceptionally constructed. Different discretionary adornments are accessible, for example, against tip bars or wheels, seat straps, customisable backrests, slant as well as lean back highlights, additional help for appendages or neck, mounts or conveying gadgets for props, walkers or oxygen tanks, drink holders, and attire defenders. Tests have additionally been made with strange variation wheels, similar to the omni wheel or the system wheel. These permit more directional development choices. Mechanization is the most often spelled term in the field of hardware. The strive after mechanization acquired numerous transformations the current advances, which had more noteworthy turn of events, is the accelerometer sensor. These had more noteworthy significance than some other innovations because of its easy-to-understand nature. Accelerometer sensor based gadgets can be effectively battery-powered to the everyday person because of its less complex activity. This gadget is compact and client can wear it to his wrist like a watch and can work it by shifting the accelerometer sensor.

C. Benefits of Present System

The design and fabrication of a Head Tilt Controlled Wheelchair comes with several benefits. Let me share a few of them with you:

1. Accessibility: Allows individuals with limited mobility or disabilities to operate the Wheelchair using Head Tilt, promoting independence and mobility.
2. User-Friendly Interface: Head Tilt provide a natural and intuitive interface, reducing the need for               complex manual controls and making the Wheelchair easier to use
3. Hands-Free Operation: Users can control the Wheelchair without the need for manual input, allowing them to perform tasks or navigate environments while keeping their hands free.
4. Efficiency: Head Tilt Control can streamline operation, allowing users to quickly and efficiently control the wheelchair without the need to physically interact with buttons or switches.
5. Safety: Head Tilt Control minimizes the risk of accidents or errors that may occur when using manual controls, enhancing overall safety for the user.
6. Customization: Head Tilt Controlled systems can be customized to recognize individual moments, providing a personalized user experience and accommodating specific needs or preferences.

The fabrication of a Head Tilt Controlled Wheelchair offers several advantages. It not only saves time and effort but also reduces costs, all while promoting environmental sustainability. This innovative solution represents a smart and convenient approach to ensuring the effective maintenance of moving.

IV. ACKNOWLEDGEMENT

We extend our sincere gratitude to all the authors whose research papers served as invaluable sources of knowledge and inspiration during the writing of this paper. Their contributions have greatly enriched our understanding and will undoubtedly guide future research endeavours in this field.

Conclusion

With the completion of our wheelchair, we have concluded that it works well for head tilt motions and it proves to be an effective solution for quadriplegic patients with more than 45 % disability or for the patients with spinal cord injury who could not move their hands and legs for driving a manual or automatic wheelchair. This system proves better than automatic joystick powered wheelchairs in terms of ease of operation and head tilt control. Also, the project comes out to be economical as compared to other available wheelchairs in the market.
