Hand Gesture based Wheel Chair Control System for Handicapped People

Why is project needed?

This project is developed for the physically handicapped people, in the market, there are many products but they do not have safety features like seat belt locking, GPS navigation, multi-control system, Hand gesture & joystick movement system.

This project gyro sensor for gesture movement which is very unique.

We have low battery indication led.

Block Diagram

Working operation

Gesture control wheelchair has two modes of operations (gyro/joystick) these sensors will give data to Atmega-328 microcontroller.

the seat belt is locked automatically once the user has seated in place.

The motor driver is interfaced for driving the motors logically as per user directions, its has GSP /GSM for getting the location information.

Gyro  Sensor

  • The gyro sensor is used to for getting the information of how much we have tilted.
  • The gyro sensor is interfaced with ATmega328 microcontroller with SPI pins.

Joystick

  • The joystick is used for manual hand operated movements.
  • Joystick gives x-axis and y-axis values to Atmega328 microcontroller for motor movements

Battery

  • In this project, we are using 12V / 2A Lead acid battery.
  • Lead acid battery is easy to charge.
  • Low maintenance
  • Low cost / easily available.

GPS / GSM

  • We are using a SIM808 module which has built-in GSM/ GPS for location identification and alerting the parents.
  • It works with low voltage 5V.
  • We are using this module for information to our parents with help of GPS and GSM.

DC motors

  • DC Motors are used for wheelchair movement.
  • 100RPM
  • 1Kgcm torque.

Applications

This project can be integrated into below areas.

  • Physically handicapped people.
  • Aged people.

Advantages

  • This is easy to install.
  • This project has safety locking system for a seat.
  • Easily / local available spare parts are used in this project when anything not functional we can replace it easily spares are available.
  • It has two modes of operations (Hand gesture and joystick).
  • It has GPS /GSM for getting location via SMS.

Disadvantages

This wheelchair cannot navigate in footsteps.

Conclusion

  • This project is very useful for physically handicapped people which helps them to navigate from place to another place without taking any other human help.

Classroom Automation using Android App Project Synopsis

Abstract

The aim of this project is to automate sound system in classrooms by which small notice announcements, emergency intimation to student or faculty of the classroom can be communicated from the control room.

In this Classroom Automation project, we are using an android app by which the user can select the classroom or group multiple classrooms to announce script, with this system human effort and time is reduced.

Announcement from control room is captured with mic and feeded into the amplified box, from that amplifier box sound signal is sent into relay switching box, from relay switching box sound is switched into the respective classroom based on user inputs from android app.

Technical Requirements:

  • ANDROID APP
  • RELAY SWITCHING SECTION
  • AMPLIFIER
  • MIC
  • CLASSROOM 1

Vehicle wrong routing detection on highways Project

Vehicle wrong routing detection on highways

Abstract

In present days many accidents are happening because of wrong route driving on highways, even after advertisements on roadside barrier gates and postures but people are not getting it used it and not following that traffic rules, to avoid these accidents we have come up with a product which will detect the vehicle in wrong route driving.

We are using a pocket-size computer called raspberry pi which will have camera attached to it on vehicle front portion to detect the wrong route indication sign boards, this raspberry pi has small speaker attached to it which will alert the driving with voice announcement not to drive in the wrong route and vehicle speed will be reduced to 30Km/hr and parking lights will on for vehicle safety.

Hardware Requirements:

  • Battery
  • Speaker
  • Parking lights
  • Power regulator unit
  • Raspberry Pi
  • Camera
  • Motor Driver

Abstract

Designing and developing an automation process for testing capacitive touch screen of mobile, there will be android app installed in mobile which displays few color blocks on lcd screen when capacitive touch pen touches the particular color blocks on lcd screen with help of automation process with X,Y and Z-axis movement by holding capacitive touch pen on Z-axis, when capacitive touch pen touches color blocks on lcd screen in this process color block on lcd screen will change if its touch sensitivity is good else the block color will remain same and feedback from android mobile is taken for evaluating performance of touch screen and feedback is displayed on LCD screen.
