Amazon Built a Roving Robot Covered in UV Light Bulbs that Could Kill the Coronavirus in Warehouses and Whole Foods Stores 122

Posted by msmash from the big-tech-getting-bigger dept.
Amazon has built robot that is designed to kill the novel coronavirus with ultraviolet light. From a report: The robot looks a little like a hotel luggage cart, with a tall metal frame attached to a rectangular wheeled bottom. One side of the frame is outfitted with at least 10 ultraviolet tube lights. In a video shared with CBS News' "60 Minutes," the robot rolls down the freezer aisle of a Whole Foods store, aiming UV light at the freezer doors. The robot could be used in warehouses and at Whole Foods stores to kill the virus on surfaces such as food, packaging, and door handles. Amazon spokeswoman Kristen Kish said the company's robotics group has been designing and testing the UV robot.

            A handle sanitizer would need one DOF, and not even that if the handles are all at the same height.

        What we should really be doing is going back to using the yellow metals (brass or bronze) for door handles and other high-touch surfaces. The copper in these alloys does a pretty good job of sanitizing the surface.

I can't imagine what else it could be), so as the robot moves down the aisle the chrome under and adjacent to the handle could reflect onto the backside, assuming chromium is reflective to UV-C.

    • There has been a significant amount of research into how much UVC over how much time is safe. Exposure is reduced by the square of distance.

      You don't want to stand 0.5 meters from the disinfecting lamp all day every day. It's okay to walk past it at a distance of 5 meters.

      • The inverse square law applies directly to point and spherical incoherent sources. For other shapes of emitters it applies to their component points, but the shape may make them combine to produce a different falloff curve.

        For instance: Light from an infinite line source falls off with the FIRST power of distance. A row of light tubes where the ends of the row is farther than the nearest point is a pretty good approximation.

        Similarly, light from an infinite plane source doesn't fall off with distance AT

Unless the light fixtures are butted up against one another, such that there is no ceiling in between fixtures, the light source isn't a plane. It's round/point/whatever sources plural.
