This document describes a prototype for a joystick-controlled wheelchair using a myRIO device and LabVIEW. The wheelchair is designed to help people with disabilities by allowing them to travel independently using a joystick. It uses a myRIO, which has inputs/outputs, an FPGA, and an ARM processor. The wheelchair is controlled via a joystick connected to the myRIO. LabVIEW software processes the joystick signals and sends commands to motors via a control circuit. The prototype aims to give more freedom and reduce caregiver burden. It has features like automatic caregiver following and computer interfacing.

2. PROTOTYPE OF WHEELCHAIR
USING MYRIO AND NI LABVIEW
NAME- PULKIT GOEL
BRANCH- ECE
GUIDED BY- MRS.SUVARNA MUJUMDAR

3. WHAT IS NI LABVIEW?
LabVIEW is a graphical programming environment
engineers use to develop automated research,
validation, and production test systems.

4. What is MYRIO?
The myRIO Student Embedded Device features I/O on both sides of the
device in the form of MXP and MSP connectors.
It includes analog inputs, analog outputs, digital I/O lines, LEDs, a push
button, an onboard accelerometer, a Xilinx FPGA, and a dual‐core ARM
Cortex‐A9 processor.
Some models also include Wi-Fi support. You can program the myRIO
Student Embedded Device with LabVIEW.
With its onboard devices, seamless software experience, and library of
courseware and tutorials, the myRIO Student Embedded Device provides
an affordable tool for students and educators.

12. As there are many people around the Globe suffering from partial
or total disabilities and it become challenging for them to
perform their daily task like walking so to tackle such problem we
made a wheelchair that could help them to travel to small places
and that to at a cheaper cost.
The prototype of the project is already working.
PROJECT- JOYSTICK CONTROLLED WHEELCHAIR
USING MYRIO

13. FEATURES
➧ Joystick Controlled
wheelchair
➧ Automatic Caregiver
Follower
➧ Computer Interface

14. HOW IT WORKS….???
● It makes use of the joystick to control the motion of the
wheelchair. The system consists of a Joystick, Computer,
Control Circuit and Motors
● The joystick sends signal to myRio then it has been
processed by the program developed using LabVIEW
● This program processes the command and corresponding
signals are send to Control Unit that drives wheelchair motor

15. MERITS
● It allows user to drive their chair using Joystick.
● Reduces dependencies on Caregiver.
● Reduces the efforts of Caregiver.
● Helps the physically challenged to enjoy outdoors activity like
exploring park, watching birds etc.

16. Automatic Caregiver
Follower
It could be helpful to both the
patient and the caregivers who
push the wheelchair.

17. Equipments Used
●LabVIEW software
●myRio
●Jumper wires
●2000mAh NiMh Battery
●Motor driver
●Chassis
● 2 DC Motors
●2 wheels
●One wheelchair
●Joystick

31. CONCLUSION
●This will help and differently abled people to go around
places and to explore the world.
●This solution provide freedom to them as they can travel
on their own without the care giver
