*1 The R&D theme "Project to develop systems to handle the social challenges of infrastructure maintenance management and renewal / Infrastructure maintenance management robot technology and non-destructive inspection equipment development / R&D of exploration robots for inflammable gas atmospheres" is a 4-year plan, of which FY2014 to FY2015 was an outsourced project and FY2016 to FY207 is a support project.
*2 Second of three hazardous area classifications: A place in which a hazardous atmosphere is likely to occur in normal operation. Applies to almost all hazardous places other than inside oil tanks (zone 0).
*3 The PTZ camera that can handle Pan (horizontal motion), Tilt (vertical motion), and Zoom (wide to zoom) was successfully incorporated through cooperation with MIYAKI ELECTRIC MFG. Co., Ltd. (Headquarters: Kameoka, Kyoto, President: Koji Kawara).
