ABSTRACT
Living conditions for the elderly have become alarmingly unsatisfactory. Nearly nine percent of persons aging seventy years and over are unable to perform one or more activities of daily living such as bathing, dressing, drinking water, using the toilet, getting in and out of bed or chairs and drinking medicines
Asilo de Molo is a home for the elderly in Iloilo City. However, the institution is currently having a shortage in their nursing staff. There is only one nurse for every twenty-four patients.
The study aimed to design an eight-inch wide and four-inch tall prototype robot that helps the bedridden and or the incapable elderly by delivering water on a regular round basis The design made use of the PIC16184 microcontroller, light sensor, assembly language program and stepper motors.
The researchers made use of the Line-Follower Method Lines where drawn on the floor to indicate the path that the robot should follow and the robot was programmed using the MPLAB which is the Assembly Language program used programming the PIC 16184 microcontroller.
The researchers built a testing area where the robot is to be tested. The results showed that the prototype was 80 accurate based on the success of four out of five trials. An error occurred due to the inconsistency of the power supply that can cause the slowing down of the stepper motors which defines the movement of the prototype.
