To reduce the risk of infection among\nfrontline workers, Prof Xu Qingsong and his team in the Faculty of Science and\nTechnology (FST) of the University of Macau (UM) have developed Smart Cleaner, a\nlow-cost intelligent disinfection robot, which can substitute for disinfection\nstaff to disinfect air and surfaces in areas with serious outbreaks. The robot\nhas been put into use in the outpatient building of Kiang Wu Hospital, some\ngovernment offices, and the UM library. The response from the users has been\nvery positive and they expressed intention to place custom orders.<\/p>
Prof Xu and his team began to develop\nthe robot in April 2020. Because the development of the components, programmes,\nmodules, appearance design and assembly were all performed in-house, they were\nable to keep the cost low, which is beneficial for the popularisation of the\nrobot. According to Prof Xu, each robot costs around MOP25,000 to MOP35,000,\nbut robots with similar functions currently sell for about MOP370,000 on the\nmarket.<\/p>
Prof Xu explains that the robot mainly\nuses 6% hydrogen peroxide disinfectant with silver ion for atomisation\ndisinfection. In previous lab tests, the disinfectant sprayed by the robot\nreached a concentration of 600-800ppm (mg\/L) in ten minutes and disinfected a\nspace of 100 square metres within 15 minutes, with 99% disinfection and\nsterilisation. Prof Xu says that the robot uses a dry atomised disinfectant\nsolution, so the chemical will dissipate quickly under ventilation instead of\nremaining in the disinfection area, which will reduce the damage to skin and\nthe respiratory tract.<\/p>

As long as the information about the\ndisinfection site is pre-set in the system, the robot can scan the site with\nits radar and automatically create a map, plan its own trajectory and\nnavigation, and avoid obstacles by scanning with the radar to disinfect as it\ngoes. Users can choose to use the handle to direct the robot according to their\nneeds or plan the disinfection route for the robot via the computer in advance.\nIn environments with poor signal reception, such as warehouses or ICU units,\nusers can use the camera and handle on the robot to view its surroundings and\ndirect it, respectively.<\/p>
