A Study on an Intelligent Drug Delivery Robot Based on ROS

When public health emergency like epidemic breaks out, there is always shortage of medical staff in isolation wards and the risk of infection is high. As for the laborious drug delivery task and the working environment where cross-infection happens easily, a solution is proposed — an intelligent robot car. This paper presents the overall plan and mechanical structure design of the robot: The hardware system is composed of STM32 as the main controller, Raspberry Pi, Iidar, camera and other devices; the robot operating software system is built based on ROS and Raspberry Pi Ubuntu environment; functions include indoor map construction, autonomous path planning, obstacle avoidance and navigation, drug delivery are implemented. The robot runs smoothly and has various and flexible functions, which can provide reference for the development of medical service robots.
