Raspberry Pi based Multi-optional Wireless Wheelchair Control and Gesture Recognized Home Assist System

Abstract

Smart Wheelchair is a controlled device designed with the help of the user command to have self-mobility. It reduces the human effort of the user and encourages wheelchair riding. In fact, it also provides an opportunity for physically impaired people to move from one location to another. The main work of this paper is to gain more information, to construct a wheelchair using Raspberry Pi and RF controller to solve the difficulties faced by the physically challenged person. The device is fitted with the RF module, GSM and GPS module, servo motor, wheelchair and the whole module is controlled by wheelchair. To achieve a desire movement, the user will provide input commands to control the wheelchair and it is interfaced by RF communication and voice command. Depending upon the user convenience either RF communication or voice command can be used. Solution has also been proposed during an emergency by using an alert system. The movements received and the hand gesture shown by the visually impaired are recognizedandcontrastedwiththemodelsstoredonthereceiver.Ifthetemplates suit the templates stored then the home appliances are managedaccordingly.

Smart Wheelchair with Advanced Assistance and Governing System for Disabled

“…A Raspberry PI zero is permitted to approach the system without showing units. TFT display is used to operate the smart wheelchair.When the touch control is given input according to different modes in it the signals are transmitted to raspberry pi zero and then the RF module which operates at 433Mhz transmit wireless signal to the receiver at the other end that operates motors connected to wheelchair.This project needs a wireless communication that is fulfilled using a rf wireless module that operates at 433Mhz and takes input four data points and outputs the signal fed to those inputs and the receiver has four data output points that fed to a micro-controller and further the controller is connected to servo motors and has a motor driver points that fed to a micro-controller and further the controller is connected to servo motors and has a motor driver connected to it to operate.the motors connected to wheels to move forward ,backward,left or right [3,5] The operation of whole circuit is done using Raspberry pi Zero 2w which has a1Ghz quad-core and 64-bit processor (Arm Cortex-A53) and stores data up-to 512MB SDRAM and this is powered using a micro USB pin. This also has and SD slot that enables to extend memory and helps connect to the virtual monitor in VNC viewer.…”

Enhanced safety and automated wheelchair for patients with mobility disability: a case study of mount Meru referral hospital, Arusha, Tnzania

“…The RF module, GSM and GPS module, servo motor, wheelchair, and device are all included. The wheelchair controls the entire module (Renuka et al, 2021). The user will offer input commands to control the desired movement.…”
