2. ABSTRACT Wheelchairs are used by the people who cannot walk due to physical illness, injury or other disability. Now-a-days development promises a wide scope in developing smart wheelchair. Wheelchair now comes in diverse selection of styles which makes it exceedingly difficult for a person to select one that properly fits their lifestyle. Our project is to implement a home navigation system, which comprises of a wheelchair which will be monitored using an android phone. Android phones being easily accessible to every household, our project will focus to operate the wheelchair that works on the inputs such as voice, touch and gesture via an android phone and navigates according to the commands provided. It is common that the elders and physically challenged people find it hard to move the wheelchair without external aid.

4. INTRODUCTION The physically handicapped person who uses traditional wheelchair is facing many problems. They need a permanent assistant while they are moving from one place to another for their day to day work. In market joystick wheelchairs exists but what if person is handicapped also with hand then what should happen!! So, we developed a voice and gesture controlled wheelchair to navigate from one place to another without any need of assistance. The old system of wheelchair is not worthy for old age people as well as handicapped people. So, voice and gesture plays a vital role regarding this problem and our system is more preferable and cost effective regarding the situation of the elderly and handicapped people.

6. Proposed solution Nowadays the handicapped people and old age people are faced a lot of problems because they are unable to move from one place to another place they are totally depended on wheel chair, and they need a permeant person to assist and control the handicapped people. So we proposed a solution to rectify this problem by designing a automatically controlled wheel chair which is controlled by his/himself only through mobile or voice.

7. COMPONENTS Hardware Node MCU ESP8266 HC-05 Bluetooth 4 Channel Relay Module DC motors Connecting wires External battery Power supply Software Arduino IDE Android Bluetooth Application

8. ESP8266 NODE MCU MODULE Node MCU is  an open source IoT platform . It includes both firmware which runs on the ESP8266 Wi-Fi SoC, and hardware which is based on the ESP-12 module. The applications in these samples that are running on Node MCU are written using Lua scripting language which is quite simple and easy to understand. Micro Controller : Ten silica 32-bit RISC CPU Xtensa LX106 Operating Voltage : 3.3V Input Voltage : 7-12V Digital I/O Pins (DIO): 16 Analog Input Pins (ADC): 1 Flash Memory: 4 MB Clock Speed: 80 MHz

9. HC-05 Bluetooth module The HC-05 is a class 2 Bluetooth module designed for transparent wireless serial communication. It is pre-configured as a slave Bluetooth device. Once it is paired to a master Bluetooth device such as PC, smart phones and tablet, its operation becomes transparent to the user. B luetooth Version: Bluetooth 2.0 + EDR Operating Voltage: 3.3V to 5V Operating Current: < 40mA (for Bluetooth communication) Operating Range: Up to 10 meters (depending on environmental factors) Default Baud Rate: 9600 bps  

10. 4 Chanel Relay Module The 4 Channel Relay Module is a convenient board which can be used to control high voltage, high current load such as motor, solenoid valves, lamps and AC load. It is designed to interface with microcontroller such as Arduino, PIC and etc. The relays terminal (COM, NO and NC) is being brought out with screw terminal. It also comes with a LED to indicate the status of relay. The 4 channel relay module can be used to control various appliances and other types of equipment with large current. The maximum output of the relay module is AC250V 10A and DC5V 10A.

11. DC MOTOR A  DC motor  is an  electrical motor  that uses direct current (DC) to produce mechanical force. The most common types rely on magnetic forces produced by currents in the coils. A DC motor is an electrical machine that converts electrical energy into mechanical energy. In a DC motor, the input electrical energy is the direct current which is transformed into the mechanical rotation. Output Voltage : 0-220VDC Max Current : 0.13A Max Output Power : 123W Max Rotation Speed : 1500rpm

12. EXTERNAL BATTERY A Rechargeable Lead Acid Batteries are used to provide the supply voltage to the Required no of motors and This type of batteries are completely rechargeable means the battery will be used until the last energy of voltage is completed. Operating Voltage : 14.4-15.0V Initial Current : 2.25A DC power : Constant Output Voltage Specific Energy : 150-190 W/kg Operating Temperature : 27 C

13. CIRCUIT BATTERY A Circuit battery is used provide the required amount of voltage to the circuit elements means it provide the less amount of voltage to the circuit elements and it is capability storage voltage is less and it is a non rechargeable battery. Operating Voltage : 4-6V Current Output : 1.0Ah Storage energy : less

14. ARDUINO IDE The Arduino Integrated Development Environment - or Arduino Software (IDE) - contains a text editor for writing code, a message area, a text console, a toolbar with buttons for common functions and a series of menus. It connects to the Arduino hardware to upload programs and communicate with them. Programs written using Arduino Software (IDE) are called  sketches . These sketches are written in the text editor and are saved with the file Extension. The editor has features for cutting/pasting and for searching/replacing text.

15. ANDROID BLUETOOTH Application The Android Bluetooth Controller is a one type of Android application which is used to connect the Bluetooth module to android mobile through Bluetooth and this application is used to control the output device automatically by connecting Bluetooth module to mobile phone. This application provides various types to control the devices like through voice commands, touch arrows and gestures.

18. advantages It is a Automatically Controlled Device. The Programming of this device is easy. Less Complexity due to reduce no of Hardware Components.   It is also provide voice commands to control the device. The device operated speed is high it will respond very less time. Implementation and Construction is Simple. It is High Reliability due to less no of Components. The system is fully automated because of the use of Arduino and motor drivers.

19. APPLICATIONS PERSONAL CONTROL HEALTH CARE FACILITY ASSISTIVE TECHNOLOGY EDUCTION AND TRAINING RESEARCH AND DEVELOPMENT VOICE RECOGNITION TV’S AND MOBILES AIR CONDITIONERS AND COOLERS

20. RESULT Voice or Mobile Controlled wheel chair using Arduino and it is controlled through voice recognition commands and touch gestures in mobile phone.

21. conclusion So we concluded that Automated wheelchair can be used to help handicapped people, especially those who are not able to move we have described a smart wheelchair equipped with sensors control that allows the rider to interact with system at various levels of abstraction. We are trying to developed a device which could make a handicap one independent and can provide extreme ease in his life. For a person no need to rely on other for his day to day work by using this project.

22. Future scope The future scope for the project "Voice-Controlled Wheelchair using Arduino" includes enhancing its functionality by integrating advanced voice recognition algorithms and machine learning models for improved accuracy and responsiveness. Additionally, exploring wireless connectivity options like Bluetooth or Wi-Fi can enable remote control and monitoring features. Further development may involve incorporating obstacle detection sensors and navigation capabilities for increased autonomy and safety. Finally, exploring accessibility features and customization options can make the wheelchair more user-friendly and adaptable to diverse needs.
