Researchers from MIT have developed a new way to keep shared spaces free of the coronavirus and other pathogens: a UVC light-equipped robot. UVC light is capable of disinfecting surfaces and neutralizing aerosolized virus particles, but it's dangerous for humans to be exposed. With this in mind, MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) teamed up with Ava Robotics to develop a robot that can travel through and disinfect spaces autonomously. The partners added a custom UVC light fixture designed by CSAIL to Ava Robotics' mobile robot base. They deployed the prototype at the Greater Boston Food Bank (GBFB).
A new robot developed by MIT in the US is being used to kill coronavirus in a 4,000-square-foot warehouse using ultraviolet light (UV) light. The autonomous machine uses a specific type of short-wavelength UV, known as UVC, to kill microorganisms and disrupt their DNA in a process known as'ultraviolet germicidal irradiation'. UVC is emitted from the bot's four vertical beams as it nips around warehouse aisles, killing 90 per cent of coronavirus particles in 30 minutes. Because UVC light is harmful to humans, the robot has to do its work alone and is sent to do its sanitising shift when human workers have clocked off. The robot can map an entire industrial facility – in this case the Great Boston Food Bank (GBFB), a US non-profit that provides hunger relief.
A robot being developed by Blue Ocean Robotics uses ultraviolet light to disinfect rooms. The Danish company is targeting the product first at hospitals, where there's a high danger of patients contracting infections. In a 2011 study, the U.S. Centers for Disease Control said patients acquired 722,000 infections during treatment at health-care facilities in the U.S. that year and 75,000 of those patients died in the hospital. It's a problem that Blue Ocean hopes to resolve with its UV disinfection robot. The robot uses large ultraviolet lamps to kill bacteria.
"We've set it to alert us if someone has a fever over 100.5 degrees Fahrenheit," Brett Smith, chief information officer of the airport's operator, Propeller Airports, said about the repurposed device. The camera screens passengers as they line up for standard security checks by the Transportation Security Administration. Passengers with high fevers are screened a second time, and ultimately the airline determines if they pose a danger to others on board, Mr. Smith said. The airport began operations in March 2019 and serves as a northwestern hub for Alaska Airlines and United Airlines. Developed in 2018, in the wake of a mass shooting in Las Vegas, Athena's gun-detecting camera operates by combining object detection, computer vision and machine-learning to identify weapons and automatically alert on-site workers and police.
