Design and Build A Logistics Delivery Drone to the Patients’ Quarantine Room Using ROS Technology Without GPS: An Initial Study

Abstract

Drones are small unmanned aircraft that usually use GPS (Global Positioning System) technology to identify areas they pass through. However, its use is limited to open areas (outdoors) where the GPS sensor can connect to satellites without obstacles that can weaken the signal. An updated idea emerged about an indoor logistics delivery drone to the patient quarantine room automatically using ROS (Robot Operating System) technology without the GPS. This drone uses the main components of a Raspberry Pi, a PX4 flight controller, and an Intel Realsense T265 camera sensor. The Intel Realsense T265 camera sensor gets the current position and the drone’s movement; then, the data is processed on the Raspberry Pi. The drone goes to the place commanded by the program on the Raspberry Pi. It automatically places the logistics according to the desired location when it reaches the specified position. Even without GPS, it is hoped that drones can make it easier for medical personnel to deliver logistics on target and minimize virus transmission because they are not close to patients. Based on three times testing, the progress obtained is quite good. The drone can fly stably. Although some accidents were in the trial, they can be handled well.
