Medical Robotics for Pandemic Crisis: A Rover-Inspired Solution for Contactless Healthcare Logistics

Abstract

This research presents an innovative application of rover technology, namely in the medical sector during pandemic scenarios like as COVID-19, when reducing physical contact among individuals is essential. The suggested device, a Medical Transportation Robot (MTR), employs a Rocker-Bogie mechanism to guarantee stability and provide smooth navigation across diverse terrains. The MTR is engineered to convey medical supplies, food, and necessities between patients and healthcare professionals, therefore decreasing the possibility of viral transmission.

The MTR boasts a six-wheeled rover design with advanced attributes, including spider-leg wheels for improved mobility. The system functions via a line-following mechanism and may be remotely operated by a smartphone application utilizing Bluetooth technology, therefore obviating the necessity for direct human participation. A collection of sensors, comprising ultrasonic and infrared types, facilitates obstacle identification and secure navigation, guaranteeing dependable operation in semi-autonomous mode. The rover's control system is constructed using Arduino and Raspberry Pi platforms, interacting with motor drivers and microcontrollers for accurate functionality.

This study delineates the concept and development of the MTR, emphasizing its practical implications in alleviating the burden of frontline healthcare professionals and enhancing safety in medical settings. The design is economical, user-friendly, and can accommodate a weight of up to 5.2 kg, rendering it a practical choice for medical transportation within hospitals. The report also examines current rover technology and explores prospective advancements in medical robots.
