We propose to produce a helping hand in the area of Rehabilitation to aid differently abled and paralyzed people in mobility by providing them with a STANDING WHEELCHAIR WITH VOICE RECOGNITION MODULE. This wheelchair promises to fulfill the need of independency of the patient as it allows them to command and control it with their voice. This is a powered wheelchair with speech recognition system. Speech recognition enables communication with machines and tools in this modern era. The module consists of a motor merged with the wheels. The commands are programmed and stored in the microcontroller which reads the given command and moves the wheelchair in the desired direction and also changes the position of the chair. It has two positions namely the sitting and standing position which is achieved by means of mechanical support systems.As a base of this project we have to design a model of the wheelchair which consists of the electronic and mechanical part. The electronic part consists of the voice recognition system (BLUETOOTH & AWR MOBILE APP) the motor and the mechanical part is the one which aids the chair to change into different positions. The mechanical part of the wheelchair consists mostly of rods and Programmable logic circuit which are needed to bring the chair to a standing position. The Bluetooth and AWR mobile app which takes voice as input for further voice recognition process. The voice recognition system has been completed. Recognize the voice pattern and store it for future purposes. The wheelchair overcomes the people who all are not able to get to a hospital quickly, Increase self-esteem, Increase social-interaction, overall quality of life (QoL).The objective of this Project is to design an automatic standing wheelchair. This wheelchair helps those who are elder, weak or patients in rehabilitation. Decrease possibility of secondary diseases. Main scope of this Project is to design a wheelchair that can reform automatically and support the costumer standing up. This kind of wheelchair will use less electrical power. Compared to traditional electrical wheelchair, it can save energy and work stable as well.We realize that few people have the means to pay for an expensive electrical model that can climb curbs and steps, while others may find those models too bulky or cumbersome for the home or workplace. By adding some new components to the standard wheelchair, we aim to provide an inexpensive alternative that increases mobility without sacrificing maneuverability. The final goal of this project is to help those who have to rely on a wheelchair to get around. Our design will provide more freedom, more independence, and more mobility at a cheaper cost than anything on the market today. We hope to give the disabled more options for their transportation needs.

Key words: Arduino Uno, Bluetooth, Driver Circuit and Voice Recognition
