Smart Walking Stick

Abstract

The main aim is to make a smart stick to avoid leg weakness, balance loss and improper navigation of indoors and outdoors. These are the reason for fall accidents occur which might be dangerous and harmful. A suitable device is needed to help the blind and elderly people to walk outside or inside with full confident and independently. The project aims at designing robot cane which will monitor normally the events that will occur and also to improvised navigation of outdoors and indoor by detecting obstacle at different heights on flat road. The cane is also modeled to consider real-time movements of person walking or their different style of walking by counting the each step they are heading to and how much they travelled. A threshold level is set for acceleration value when person walks. Combination of ultrasonic sensor and force sensor placed in the tip of shoe which will help to measure the distance between stick and leg. If a person tend to fall his hand's pressure will be more than usual one and pressure sensor will sense that pressure and force will be exerted to the shoe. When output will be more than threshold value then alarm is activated.
