“…Self-driving vehicles have also proven to be crucial in the fight against the global pandemic, reducing the burden of COVID by delivering medical supplies and food to healthcare providers and patients in infected areas and sanitising buildings and common areas to prevent the spread of the disease [19], [20]. The building blocks of medical treatment are essential in the fight against pandemics.…”

Every country in the globe has been profoundly affected by the coronavirus epidemic, and these countries are struggling with how to clean the affected areas quickly and effectively. This project aims to contribute to the fight against the spread of the coronavirus by quickly, safely, and effectively cleaning medical clinics. Regular cleaning and disinfection might reassure people and increase their confidence in the lessened risk of the spread of communicable diseases. Robots that use ultraviolet C (UVC) sanitizers can quickly and effectively clean the clinic rooms. In addition to cleaning patient seating areas, clinical equipment, restrooms, and above controls. The use of UVC technology effectively eliminates airborne germs in medical clinics. The results of UVC disinfection performance indicated a 92% reduction in the total bacterial count (TBC) at 0.5 metres from the robot after 8 minutes of UVC irradiation.

“…Examples of both types of platforms include the following: The I-Robot UVC (Moez, 2020), which is equipped with two UVC lamps on the top and eight lamps around the central column, and whose disinfection effect was evaluated by remotely detecting the disinfection time. The mobile UVC lamps in Time Medical System (2020) presented a superior software system, including environment mapping and semi-autonomous navigation. The research in Conroy et al (2021) offered an effective equipment support system for indoor operation, such as a long-term power supply system and high payload performance, with an optimized path-planning algorithm. Manufactured by Xenex (a Texas-based company), the “Little Moe” UVC-lamp disinfection robot (CBS News, 2021) has been clinically used in local hospitals and has a short disinfection process. The robot in Pacharawan et al (2019) comprises three 19.3-W UV lamps, placed 35 cm away from the robot, configured in an all-round radiation design. With an embedded Raspberry Pi system to achieve navigation and collision detection, it has a disinfection efficiency of under 8 s. The robot in Vyshnavi et al (2020) is equipped with three 20-W UV lamps, an embedded Arduino system and PIR sensors, and has the ability to generate a pre-defined path and detect its surroundings. To protect people’s health, it is also necessary to keep them far away from the robot disinfection process because of the strong UV radiation. Khabibullo et al (2020) consider confidence, security, novelty, multi-functionality and cost in regards to their proposed disinfection robot. The Phollower mobile robot (Ján et al , 2020) is equipped with advanced components and sensors, and uses embedded navigation and localization software to construct its maps. Developed by UVER, their UV LED sterilization robot (Korea Association of Robot Industry, 2020) is an air sterilization device that uses collision detection and obstacle avoidance, and is equipped with a multi-wavelength UV LED and one robotic arm which can drive eight axes in 360 degrees. …”

Purpose The disinfection robot developed by the authors and team focuses on achieving fast and precise disinfection under a given or specific disinfection zone. This looks to solve problems with traditional robots that pay less attention to the level, efficiency and zones of disinfection. To effectively support and guarantee normal running for the whole system, a digital twin system is applied to the disinfection robot. This study aims to achieve fast, precise and thorough disinfection via the developed mobile robot. Design/methodology/approach The designed robot is composed primarily of the following three parts: a mobile platform, a six-axis robotic arm and a ultraviolet-C (UVC) LED array. The UVC LED array is installed on the end-effector to achieve large-scale, precise manipulation. The adoption of all types of advanced sensors and the development of an intuitive and user-friendly client interface are helpful in achieving remote control, path planning, data monitoring and custom disinfection functions. Findings Disinfection of three different locations in the laboratory was performed; the dosage distribution of the surface as radiated by the UVC robot was detected; and feasibility of development was validated. Originality/value The developed disinfection robot achieved fast, precise and thorough disinfection for a given or specific disinfection zone.

“…Recently, many UV-C-based devices and autonomous robots are developed for disinfection purposes in hospitals and/or medical centers [10][11][12][13]. To optimise their design, factors directly affecting the germ-killing efficiency, e.g., UV dose and intensity, should be taken into account.…”

Disinfection performance of an ultraviolet lamp: a CFD investigation

Ultraviolet (UV)-based devices have shown their effectiveness on various germicidal purposes. To serve their design optimisation, the disinfection effectiveness of a vertically cylindrical UV lamp, whose wattage ranges from P = 30 − 100 W, is numerically investigated in this work. The UV radiation is solved by the Finite Volume Method together with the Discrete Ordinates model. Various results for the UV intensity and its bactericidal effects against several popular virus types, i.e., Corona-SARS, Herpes (type 2), and HIV, are reported and analysed in detail. Results show that the UV irradiance is greatly dependent on the lamp power. Additionally, it is indicated that the higher the lamp wattage employed, the larger the bactericidal rate is observed, resulting in the greater effectiveness of the UV disinfection process. Nevertheless, the wattage of P ≤ 100W is determined to be insufficient for an effective disinfection performance in a whole room; higher values of power must hence be considered in case intensive sterilization is required. Furthermore, the germicidal effect gets reduced with the viruses less sensitive to UV rays, e.g, the bactericidal rate against the HIV virus is only ∼8.98% at the surrounding walls.
