Walking Assistance Exoskeleton

Project Title

Walking Assistance Exoskeleton

Project Area of Specialization Biomedical EngineeringProject Summary

Introduction:

In this project, we designed an FSR (Force Sensing Resistor) based knee assistive exoskeleton using FSR sensors, wearable brace support suit, stepper motor, DC source supply, and a UNO Arduino which will help people suffering from knee joint movement to walk properly

Objective:

Our main objective is to give relief for people suffering from Osteoarthritis called degenerative arthritis, So that they could walk properly and it will be helpful to restore their lost freedom 

•These Exoskeletons will help elderly people who face difficulties in walking.

•The bilateral motion of the exoskeleton will help people having lower limbs dysfunction and those who suffer from gait impairments.

•Moreover, this walking assistance exoskeleton can be used in the military where soldiers have to walk all day long on different un-even surfaces. It will reduce the metabolic cost and they can use that energy for other work.

Project Objectives

Objective:

Our main objective is to give relief to people suffering from Osteoarthritis called degenerative arthritis So that they could walk properly and it will be helpful to restore their lost freedom 

Applications:

•These Exoskeletons will help elderly people who face difficulties in walking.

 

Project Implementation Method

We tested our exoskeleton on a patient who was suffering from one knee flexion and extension, after wearing our model he became able to walk properly and without any aid support. It was a great achievement of our goal.

Since our main goal was to make a person able to walk who faces difficulty in knee flexion and extension during the walk and to give them relief from a wheelchair and to give the individual complete independence.
 

Benefits of the Project

•These Exoskeletons will help elderly people who face difficulties in walking.

•

•The bilateral motion of the exoskeleton will help people having lower limbs dysfunction and those who suffer from gait impairments.

•

•Moreover, this walking assistance exoskeleton can be used in the military where soldiers have to walk all day long on different un-even surfaces. It will reduce the metabolic cost and they can use that energy for other work.

 

Technical Details of Final Deliverable

FSR (Force Sensing Resistor) based knee assistive exoskeleton using FSR sensors, wearable brace support suit, stepper motor, DC source supply, and a UNO Arduino which will help people suffering from knee joint movement to walk properly without any aid of a wheelchair or any support.

Basically, we are using two approaches to do the whole working of the movement 

1_Force prediction approach

2_Movement of the knee through linear actuation

Methodology:

Two FSR sensors which are to be connected below the toe decide the movement of the stepper motor and as the stepper motor is directly connected to the knee movement through a linear actuator. Whenever a person moves his toe forward the FSR sensor presses and gives a respective response to the microcontroller and the microcontroller gives a signal to the motor in this way motor moves the shank and gives a proper walk.
