Project Summary

The aim of introducing Smart E-wheelchairs is to facilitate elderly and paraplegic people. Paraplegic people face problems while going from one place to another place. Wheelchair is one of the most commonly used supporting devices to uphold mobility and enhance quality of life for people who have difficulties in walking. Wheelchair provides the user the freedom to move around, allowing the user to perform day to day physical activity. If a paraplegic person uses simple wheelchair than he/she needs an attendant who helps them to perform the activity. Smart E-wheelchairs is a ride solution to solve the problem faced by disable people. It allows the user to get around and undertake daily activities without assistance. It makes paraplegic person independent. They will simply have to install an application on their cell phones and fill an application to get wheelchairs services. By using android smartphone, the user can select the specified direction displayed within the four quadrants on the screen of the android smartphone to control the wheelchair. An Arduino Mega is basically used to execute all commands. Moreover, MD30C motor driver and HC05 Bluetooth module are used in this system. This system is mainly designed to save time and energy of the user.

Project Objectives

The objective of Smart E-wheelchair System is to make physically disabled student independent.
Movement of wheelchair can be controlled by using android application. With the help of this functionality user don’t need any attendant. The electronics wheelchair presents in marketplace are too much costly. A common person cannot afford to buy that wheelchair. The electric wheelchair we are going to make is affordable by a any person. 
The following aspects were considered in the choice of a design solution:
•    Installation costs
•    Time savings
•    Reliability
•    Power consumption
•    Maintenance
•    Expandability
A critical consideration is the installation costs, since costs generally determine the feasibility and viability of a project.

Project Implementation Method

The project entitled “SMART E-Wheelchairs” is a combination of IoT and Android base logic. Our product will consist of wheelchair infrastructure and an android application that work and communicate effectively with each other. By using smartphone, the user can determine the wheelchair’s movement by selecting the desired direction on the android smartphone phone screen. The command given by the user will be forwarded to the Arduino mega via Bluetooth. The Bluetooth will convert the commands given by the user in a binary format and send them to the Arduino Mega. Arduino mega will read and execute the command and lastly send the digital values to the motor driver device. The motor driver will direct the wheelchair according to the command given. When the user selects the “Go” arrow, the wheelchair will move in a forward direction, “Back” arrow prompts the wheelchair to move backward, and “Left” arrow causes the wheelchair to turn left, and “Right” arrow makes the wheelchair turn right.  The project entitled “SMART E-WHEELCHAIR” is a combination of IOT and android base development.

1)    In IOT base development we use Motor driver (L298N), DC motor, HC-05 Bluetooth module, Arduino Mega, Power supply, capacitor, LM7809 and wheelchair. These components will combine to make electric wheelchair. We use Arduino IDE for coding in chips.

2)    In the android base development phase, we will develop an application that is used to control a wheelchair. For front end coding we use XML language. For back end coding, we use JAVA language. The developmental phase of the application consists of a graphical user interface and movement functionality of the wheelchair using mobile application. Application would provide a user-friendly display, easy to use and operate.

Benefits of the Project

The main features of Smart E-Wheelchair are following

1) Easy to use just by installing the application.
2) Less expensive electrical wheelchair and easily affordable by any person
3) Make the disable person independent
4) Helps to implement movement for disabled people and aged people who can’t move properly.
5) Reduces  dependency on other human drive
6) It provides smooth movement for physically challenged people.
7) Large battery timing
