In the evolving situation of highly infectious coronavirus,the number of confirmed cases in India has largely increased,which has resulted in a shortage of health care resources.Thus,the Ministry of Health and Family Welfare-Government of India issued guidelines for the‘Home isolation of COVID-19 positive patients’methodology for asymptomatic patients or with mild symptoms.During home isolation,the patients are required to monitor and record the pulse rate,body temperature,and oxygen saturation three times a day.This paper proposes a system that can request data from the required sensor to measure the pulse rate,body temperature,or oxygen saturation.The requested data is sensed by the respective sensor placed near the patients’body and sent to the CAN data logger over the CAN bus.The CAN data logger live streams the sensor values and stores the same to an excel sheet along with details like the patient’s name,patient’s age,and date.The physicians can then access this information. 展开更多

The prime reason for proposing the work is designing and developing a low-cost guided wireless Unmanned Ground Vehicle(UGV)for use in hospitals for assistance in contactless drug delivery in COVID-19 wards.The Robot is designed as per the requirements and technical specifications required for the healthcare facility.After a detailed survey and tests of various mechanisms for steering and structure of UGV,the best mechanism preferred for steering articulated and for body structure is hexagonal as this approach provides decent performance and stability required to achieve the objective.The UGV has multiple sensors onboard,such as a Camera,GPS module,Hydrogen,and Carbon Gas sensor,Raindrop sensor,and an ultrasonic range finder on UGV for the end-user to understand the circumferential environment and status of UGV.The data and control options are displayed on any phone or computer present in the Wi-Fi zones only if the user login is validated.ESP-32 microcontroller is the prime component utilized to establish reliable wireless communication between the user and UGV.These days,the demand for robot vehicles in hospitals has increased rapidly due to pandemic outbreaks as using this makes a contactless delivery of the medicinal drug.These systems are designed specifically to assist humans in the current situation where life can be at risk for healthcare facilities.In addition,the robot vehicle is suitable for many other applications like supervision,sanitization,carrying medicines and medical equipment for delivery,delivery of food and used dishes,laundry,garbage,laboratory samples,and additional supply. 展开更多
