Design and Implementation of Multipurpose Robot for Covid-19 Ward

A multipurpose robot is a system for the covid-19 ward to provide support for serving food, medication, perform temperature check etc., for the covid positive patients without making more efforts by the medical or frontline workers towards the care of patients. As everyone there is a high risk getting infected by the virus. So, to avoid visiting rooms by the staff, multipurpose robot can minimize the contacts of patients and frontline workers or medical staff. The robot is controlled by the user using a transmitter section / remote. The main purpose of the robot is to move around, serve the food, check patient vital parameters like temperature, heart rate, SpO2 level wirelessly without making any contact with the patient and can transmit live video of patient using an IP web camera which will be placed on the robot. It will also help to navigate the directions in the hospital so that anyone can easily handle the robot. For the movement of robot from one place to other, authors have used 4 motors with dedicated wheels attached to them, which can be controlled by microcontroller using RF wireless communication module. The robot will be robust enough that it can sustain approximately 5 to 10 kg weight on it. Also, the patients can have a discussion with their families because everyone know family member are not allowed in the covid ward to visit the patient. The transmitter section plays a role of master and the robot plays the role of slave in this system. The multipurpose robot has many advantages with it as it is a low-cost system which requires low maintenance, easy to use, easy to deploy and can-do surveillance as well.
