Automatic throat swab robots have been launched in China to collect samples in COVID-19 testing, with reasonable sampling accuracy and efficiency. The developers said that they have gotten inquiries from several Chinese cities such as Omicron-hit Shanghai, and the robots could replace humans in this process in the future.
Jointly developed by the Advanced Mechanism and Roboticized Equipment Lab at Tsinghua University and engineers from Tsingke+ Research Institute, the robots were designed to ease the burden of medical workers in mass COVID-19 nucleic acid testing.
Developers said they are improving the throat swab robots based on feedback from the experiment and testing phases and will hand them over to the local authority in charge of pandemic control in Yantai Economic & Technological Development Area in East China's Shandong Province by the end of this weekend.
According to the researchers at Tsinghua University, it currently takes the robot 42 seconds to finish the sampling process for one person.
"Early experiments on volunteers proved the accuracy of the mechanical arm's automatic sampling, which showed no significant difference compared with manual sampling," said the researchers.
Developers said they will continue to speed up the robots' sampling efficiency, add testing and analyzing functions, and lower the costs, in order to prepare for the possible replacement of human operators in nucleic acid testing at sites including hospitals, communities, schools and traffic hubs including airports, harbors and train stations.
