$RGGI has teamed up with a sensor technology firm to develop human presence sensors for its ultraviolet-C (UVC) Pull Buddy Autonomous Mobile Robot (AMR). The UVC Pull Buddy uses 245 nm UVC lights to disinfect facilities and eliminate deadly pathogens such SARS-CoV-2, which causes COVID-19. Exposure to UVC light is dangerous to humans, making the need to detect people essential for safe operation of the Pull Buddy AMR.https://finance.yahoo.com/news/resgreen-group-develop-human-presence-120000847.html
