Mechatronic Systems Design of ROHNI-1: Hybrid Cyber-Human Medical Robot for COVID-19 Health Surveillance at Wholesale-Supermarket Entrances

The critical situation of COVID-19 widespread in Perú from the beginning of year 2020, has been maximized by the avoidance of social distancing reflected in crowded public places where most people go without any personal protective equipment (PPEs) leading to higher risk of virus transmission. Therefore, an innovative research has been conducted in 2020 under the supervision of the Mechatronic Engineering Laboratory at Ricardo Palma University and Bioastronautics & Space Mechatronics Research Group, resulting in the proposed project named “ROHNI-1” medical robot, as Social Humanoid Machine, that is going to be located at the entrance of a wholesale-supermarket. It is composed by 3 wheels in the chassis-base and 2 anthropomorphic arms of 4 DOF each. In order to perform an efficient human-machine interaction, it can develop 3 functions such as Detection of mask, Disinfection of hands and Monitoring of vital signs. This study presents a mechatronics conceptual design using the software SolidWorks 2020 for 3D mechanical systems development, Proteus 8 for electrical and electronics circuit technical schematics, and also, Matlab 2020a for kinematic motion testing of the robotic arms. In conclusion, favourable simulation results were achieved; the robot manufacturing is expected to be ready by 2021, and due to frugal-innovation engineering analysis, it is planned to be donated to Latin American countries working with supermarket-chains.
