Description

Our primary aim is to focus on those elderly people who suffer from osteoarthritis, myasthenia gravis, etc. We provide them medicine on time by means of automated Medbot. We enable Bluetooth module to track their movements and also to monitor them even with smart phones. In our prototype we have provided necessary space to place medicine and also provide water. We had installed necessary sensors which can detect the surrounding and can move around without having any trouble. Extra provision is available for keeping other things like shoes ,spectacles,etc..

ASSEMBLING PROCESS:

First we have connect arduino with l293d motor shield driver.
Then we connnect four BO gear motor (M1,M2,M3,M4) to l293d motor shield driver.
After we connect bluetooth module (hc-05) to shield.
Then connect arduino uno to laptop/pc by USB cable and upload code given in codes part.
All the components are connected with help of jumper wires.

We install bluetooth connect car from playstore.
We give power supply by using 18650 3.7 Li-on battery to shield.
Next we take arduino nano connect with servo and ultrasonic sensor as per given circuit diagram.
Then connect arduino nano to laptop/pc by USB cable and upload code given in codes part.
After give 9v volt power supply to arduino nano by using jumper wires.
