• a physical method for example, a method in which the type specifying means is a baffle plate to be mounted by changing the position for each work assembly, or a method in which a protrusion provided at a different position of each work assembly is detected. Conceivable.
• the types of work assemblies are not limited to the above two types, and three or more types of work assemblies including the following ultraviolet irradiation assembly and radiation dose measurement assembly may be mounted on the traveling assembly.
• This work port is not limited to liquid application and suction cleaning, but it also irradiates the floor coated with UV curable resin with UV light to coat the floor surface.
• Ultraviolet irradiation assembly medical facilities and research facilities that handle radioactive materials
• Various work assemblies are exchanged and mounted, such as a radiation dose measurement assembly that measures the distribution of radiation dose on floors, and a gloss measurement assembly that measures the distribution of gloss on floors coated with PAX UV curable resin. It is possible to do.
