Completion of initial prototype “One-Mile Mobility” in a business partnershipwith Aisan Technology Co., Ltd. and Tier IV, Inc.
Okaya & Co., Ltd. has agreed to form a business partnership with Aisan Technology Co., Ltd. andTier IV, Inc. towards business commercialization of the “One-Mile Mobility”. Of the current
autonomous driving technologies, the “One-Mile Mobility” on public roads that Okaya & Co., Ltd.
focuses on is one step ahead, and the formation of a new, future market is expected. We arepleased to announce that we have completed the Initial prototype unit (popularly known as: Milee).
[Initial Prototype]
Milee is a fully automatic operation EV for the “last one mile”, requiring no handle, accelerator, orbrake. Tier IV, Inc. has developed this initial prototype unit through the “One-Mile Mobility” Project inwhich Okaya & Co., Ltd. and Aisan Technology Co., Ltd. have been making collaborative progress.
[Picture: Above diagram is the image design,and the diagram below is a picture of an actual vehicle.][Reference Specs]- Vehicle: Motor-driven golf cart (Yamaha Motor Co., Ltd.)- Vehicle Body: 3D Printer Resin Material (Kabuku Inc.)- ECU: DRIVE PX Platform (NVIDIA Corporation)- Size: 3,209 mm long, 1,488 mm wide, and 1,944 mm high- Weight: approx. 700kg

Milee uses automatic operation software “Autoware” under development by Tier IV. In addition, themaps and devices such as “High Precision 3-Dimensional Mapping” and Laser Scanner provided by
Aisan Technology have been built in. This enabled us to realize the major functions needed forcomplete automatic operation, such as object detection of the surroundings, estimation of thevehicle’s position, formulating travel routes, and the operation judgment.
[Future Development]
Okaya & Co., Ltd. will carry out verification tests from Spring 2018 onward using this initial prototype
unit. We will make a separate public announcement later regarding the specific testing sites. We
hypothesize that Millee will be mainly used as a mobility method near urban cities and areas
between plains and mountains; with concern over future driver shortages, we intend to aim
development at passenger services/logistics services. Our company has a partnership with Aisan
Technology and Tier IV, and while we steadily proceed with the verification tests we will aim atcommercialization of the “One-Mile Mobility” in the year 2019.
Furthermore, we are scheduled to showcase this initial prototype unit at “GTC Japan 2017 (HiltonTokyo Odaiba)” from December 12 through December 13, 2017, and at “Autonomous Driving
Technology Expo (Tokyo Big Site)” from January 17 through January 19, 2018. We at Okaya & Co.,
Ltd. sincerely await your visit.
* “One-Mile Mobility” is an approach for solving social problems that more particularly refers to the“Next Generation Terminal Traffic System”, where a low-speed autonomous driving technology
utilizes small mobility in limited regions. Low-speed autonomous driving assumes speeds of roughly
30 km/hour or slower, which the competent authority in the USA and the Japan’s Cabinet Office
define as “Level 4” (Complete Autonomous Driving).
