Mechanical and Entire Setup

The step by step procedures

The motors were set through the cycle wheels

A box was set to hold the necessary accessories

Mechanical and Entire Setup (cont.)

The step by step procedures A relay was connected to maintain the voltage

variation

The carrier parts were attached to hold two LCDdisplays and IR sensor

The step by step procedures Finally it was colored The individual circuits

were implemented and placed

Results (cont.)

Difficulties Faced through the work

It was difficult to find higher rpm motor

Relay was used instead of motor driver

Speed was comparatively higher The placement of the sensors

Limitation

It is not capable with reverse movement Voice command procedure takes time to

apply IR sensor is placed with a little bit height

from the ground IR sensor is not so much sensitive

Floor-mapping technology (GPS) Strong communication system (GSM) Easier movement using Tongue Motion Driver Improve the directory options by eye movement Using caterpillar tracks for more safety Providing heart beat sensor, automatic insulin

injection system for handicapped diabetic patient Power the entire system by solar charge

Future Application

Summary

Floor-mapping technology

Future Work

This technology can move the user to a desired direction within the limit of Wifi network. This can also be modified by GPS system by which the path will be sensed with the command. [9]

Strong communication system

Future Work (Cont.)

This technology one can be enjoy the opportunity to share the message with the user from a long distance.This process is not cost effective as the GSM based technology consume cost to send the message via mobile network. [10]

Easier movement using Tongue Motion Driver

Future Work (Cont.)

The entirely paralyzed handicapped people can motivate his/her movement by this technology.The permanent magnet is responsible to sense the movement of the tongue and the signal is transmitted to the control unit via hall sensor. [11]

Improve the command system by eye movement mechanism

Future Work (Cont.)

The fundamental procedure will follow the position of eye over this technology. The completely paralyzed handicapped people can use this for better and easier movement.[12]

Using caterpillar track for more safety purpose

Future Work (Cont.)

The Caterpillar Track will be too helpful for the journey towards the stairs and hard surfaces. The normal wheel is used instead of the traditional normal wheel for only safety purpose. [13]

Providing heart beat sensor, automatic insulin injection system for handicapped diabetic patient

Future Work (Cont.)

The heart beat sensor and artificial pancreas can be set up with the wheelchair for the diabetic handicapped patient for best observation of health issue. The offered LCD display will be responsible to inform the update and other belongings.

Power the entire system by solar charge

Future Work (Cont.)

This technology enhance the case of renewing the energy power by which one can consume the overall cost of electricity. The moderate efficiency will be enough on the behalf of the movement of handicapped persons through this wheelchair. [14]

Provide in prompt to voice command for movement

Make the entire system using wire instead of Bluetooth system to reduce cost

Place IR and Sonar in ideal position with large amount to ensure better movement

Manufacture by shaft with mechanical methodology to reduce the several amount of collision

Possible Improvement of Our Project

Summary

Conclusion

The bright and innovative design will help the handicapped person adapting with sophisticated lifestyle. We hope our project will be helpful for the users. For the revolution obviously this chair has to be further developed and manufactured. The world appreciates the continuous invention of engineers with pioneering excellences. We strongly believe that “ Intelligent wheelchair for Handicapped Persons” will be one of them.
