In February this year, news showed that in response to the epidemic, Chinese medical equipment supplier Sunay Healthcare Suppl purchased a self-driving disinfection robot with UVC lights from the Danish company UVD Robots for hospital sterilization and disinfection.
It is reported that the UVD Robots robot won the 2019 Oscar Award-IERA Award for the robot industry. At present, UVD Robots has been sold in more than 40 countries. In addition to the medical markets in Europe and the United States, the company has provided self-driving disinfection robots to hospitals in other parts of Asia.
After UVD Robots, a company in Singapore has also launched an automatic ultraviolet disinfection robot that may kill coronavirus.
According to foreign media reports, Singapore-listed company Digital Safety (DiSa for short) just launched the first automatic ultraviolet disinfection robot in Singapore in March. This robot was "born" at the time of the outbreak of a new coronavirus. According to reports, it took DiSa only two months to develop this automatic UV disinfection robot.
From a technical point of view, this robot has not achieved a major breakthrough. DiSa also fixes some ultraviolet emission tubes on an automatic robot, automatic navigation robot or ground robot. The sterilization and disinfection method is to use a short-wave UVC light source with sufficient disinfection effect to irradiate bacteria, viruses and other microorganisms to cause death.
While the UVC lamp tube kills nearby microorganisms, the robot can reach all parts of the room autonomously. The robot is also equipped with a laser sensor, which can draw the layout of the room, and then automatically disinfect each area.
At the same time, the automatic disinfection robot can also detect obstacles and avoid them automatically without manual assistance. However, because UV-C radiation is harmful to humans, the robot needs to be disinfected under unmanned conditions. DiSa estimates that it takes 15 minutes for an automated robot to disinfect a room, but the size of the room is unspecified.
It is worth noting that despite its comparative advantages, automatic UV disinfection robots are unlikely to provide comprehensive protection against new coronaviruses. If the UVC light wave is blocked by an object, it is impossible to disinfect those places that cannot receive light.
In any case, DiSa will soon promote its automatic UV disinfection robots to major retail stores and commercial establishments. At the same time, the company also plans to produce smaller home versions, which are expected to be launched in the second half of this year.
