Abstract

Human-robot interaction (HRI) is the field investigating on how humans interact with robots. The main purpose of this project is to develop a simple robot with HRI features to solve the waiting problem of hospital patients and visitors to get attention from nurses. Interactive feature of the robot for HRI purpose is a touchscreen mounted on a line following mobile platform and the robot is called using a wireless remote call button. This project consists of planning, design, product development and analysis stage. Planning stage covers literature review and methodology. Design stage include using mechanical design software; SolidWorks 2013 to design the outlook of the HRI robot, electrical design software; Proteus to design and simulation to check hardware connections and current flow on circuit, for interface designing; Nextion Editor software was used to design and create application for interaction purpose. Two different conceptual designs were produced and finalized to select the best one. The selected design was fabricated. The product then was mounted with Arduino Mega microcontroller. The microcontroller goes through programming phase, where a series of simple reliability tests was conducted; line following test, wireless remote call button test and touchscreen test. For the analysis stage, a usability test was conducted at Pusat Kesihatan UTeM to carry out observations and distribute survey questions to patient volunteers. Results were analysed and documented. From observations, the tested patients could communicate with the robot and request for services provided by the robot. This shows that this simple robot with HRI features was able to interact with patients in hospital environment.
