Demonstration test of the unmanned security and disinfection robot "PATORO ™" at the first underground shopping mall Shinjuku Subnade

NIKKEN SEKKEI CIVIL ENGINEERING LTD in Chuo-ku, Osaka, (President & Representative Director, Kyoji Okada) and ZMP Inc. in Bunkyo-ku, Tokyo, (CEO, Hisashi Taniguchi) with the cooperation of Shinjuku Subnade Co., Ltd. in Shinjuku-ku, Tokyo, (President and CEO, Yoshihiko Futami) will conduct an unmanned disinfectant spraying demonstration test on November 19 with the unmanned security and disinfection robot "PATORO ™" (hereinafter "PATORO").

Shinjuku Subnade is an underground shopping center directly connected to Shinjuku Station (JR, Tokyo Metro, Seibu Railway), and is a commercial facility that plays a central role in Japan's most popular city. The shortening business hours requested by the Tokyo Metropolitan Government in the 23 wards as a countermeasure against the new coronavirus has been lifted. In order for customers visiting Shinjuku to use the underground shopping center with peace of mind, we have decided to conduct a demonstration test of unmanned disinfection in the underground shopping center passage as part of future measures against corona infection.

In this demonstration experiment, we used the unmanned security and disinfection robot "PATORO" and the test has carried out in a part of the passage in the underground mall. Moving autonomously in a preset course, PATORO sprays disinfectant on the knobs of the fireproof doors where each store staff goes in and out, and the floor of the passage where an unspecified number of people come and go. We will also introduce "ROBO-HI®", a cloud system for remote monitoring and control that allows you to check the state of the camera mounted on the robot via the Internet by installing a monitor in a remote location.

The state of this demonstration test will be released to the media as follows.
If you are interested in media coverage, please contact Nikken Sekkei Civil and ZMP.

・ Date and time: November 19, 2020 (Thursday) from 14:30 to 16:30
・ Location: Part of the Shinjuku Subnade underground shopping center (passage)

■ About the unmanned security and disinfection robot "PATORO"

"PATORO" is one of the "low-speed Autonomous Driving three brothers robots" that runs at walking speed, and has the same rich expression as the Unmanned delivery robot "DeliRo™" and the Single-seater robot "RakuRo™". It is a robot developed with the aim of coexisting with people through voice communication. Using multiple cameras and laser sensors to detect passersby in the surroundings, it has functions to automatically avoid and stop safely in front of obstacles, as well as to announce by voice and ask you to give way. It is a robot that allows people around you to live comfortably and safely. PATORO is equipped with an optional disinfectant spraying function. In order to realize a safe and secure world in the future, we meet the needs for preventing the spread of infection in places where many people live, come and go such as airports, stations, office buildings, commercial facilities, hospitals and welfare facilities.
