Smart Walking Stick
The Smart Walking stick consists of different parts. An RGB board that uses servos and wheels to follow lines, one line leads to a post box in which a grabber can take letters to the owner. A Zero crossing detector that picks up 3 different frequencies, smoke alarm, phone ringing and a doorbell ringing. A Real-time clock that has a LCD screen displaying time, temperature and an alarm. The purpose of this project is to create a working innovative smart walking stick that is easy to use, so it can make a disabled or elderly persons’ day to day life easier.
The device contains a few different aspects. The main part is the RGB board. The purpose of this is when a button is pressed, the device will follow colored lines throughout someone’s house, this device is aimed mainly towards a visually impaired person. One of the lines will go to the person’s letter box, where a grabber at the front of the device will grab the letters and follow the line back to the person. There will also be an alarm clock feature that sets off a buzzer, LEDs and an LCD screen that displays the alarms. A Zero Crossing detector will be implemented into the project, this means when certain noises occur LEDs will flash e.g. Red LEDs for a smoke alarm.
Most elderly people need either a walking stick or some support system. The device allows an elderly person greater independence. It allows a person to move about their home without assistance from anyone else. If a doorbell or phone is ringing or a smoke alarm is going off, it means the person will be made aware.
