Tokyo Kuei and the University of Tokyo Production Giken announced the commercialization of the twin -style unmanned boat "MMC"

　The Tokyo Kui and the University of Tokyo Production Technology Research Institute have a two -style unmanned boat "MULTI MOVER CATAMARAN" (hereinafter MMC), which has been conducting joint research and development on December 3, 2021.did.Customization is customized manufacturing according to the customer's application, and the price is 750,000 yen.It will be sold around the summer of 2022.There are three main features of the aircraft."Stability", which is suitable for shooting resistant to shaking, "maneuverability" that can not only turn back and forth but also turn around, and "portable" that can be folded and carried.

　Since MMC is a wired unmanned boat developed using the components of underwater drone Blue Rov2, there is no fear of communication lost even in an environment with shields from the pilot point, and it can be operated with confidence.The assumed application is to check the video in places where it is difficult to enter, whether it is an aerial drone or an underwater drone, such as a pier, the lower part of the bridge, or the culvert of carbert (culvert).

　On the other hand, inspection of fishery facilities such as fixed networks and cultivation networks, and inspection of renewable energy facilities such as offshore wind power and wave power generation requires a wide range of movement in the ocean.For this reason, the wireless communication model of MMC is also commercialized in parallel.

　The structure of the MMC consists of two air tube floats, the rack that connects it, and two screws.The two air tube floats can be taken off, rounded and carried, and air pumps for bicycles are also possible.The rack part is also foldable, and can be stored in a 160cm size box and delivered home delivery.

　The rack is equipped with a control unit in the box and a camera for maneuvering.In addition, a stick from a rack is suspended, and various devices can be installed according to the application, such as a camera for underwater photography and a water quality meter.The aircraft weight is 20 kg, and the installation part can be handled up to about 10 kg.

　What is unique is that the fire hose is used as an air tube float material.Since the firefighting hose equipped with the fire truck is used in turn, it is highly intensity and can be folded, and it can be wiped immediately after use on the water.

　We are particular about the details in pursuit of stability.The front of the air tube was made into a conical structure, and the structure was reduced as much as possible by preventing the bow from lifting while sailing.In addition, the structure is easy to rotate by changing the direction with only the screw, not the rudder.As a result, it can be stable while turning on the spot even in narrow places such as under the pier.

Hiratsuka City and Hiratsuka City Fisheries Cooperative cooperated

　The development of MMC has been promoted with the support of Hiratsuka City and Hiratsuka City Fisheries Cooperative.Hiratsuka City and the University of Tokyo Production Technology Research Institute have been promoting demonstration experiments at wave power plants for some time, and concluding a collaboration agreement, promoting research and development of marine utilization technology, creating new industries and developing human resources.We have contributed to.

　In 2009, Hiratsuka City Fisheries Cooperative was organized by fisheries -related companies and organizations, including the University of Tokyo Production Technology Research Institute, Hiratsuka City, Kanagawa Prefectural Fisheries Technology Center Sagami Bay Experiment, Hiratsuka Agricultural High School (now Hiratsuka Agricultural High School).It is said that the Hiratsuka Fisheries New Technology Study Group has been established to cooperate with industry -academia.

　In this development of MMC, Hiratsuka City and Hiratsuka City Fisheries Cooperative have also evaluated the results of experimental results, including coordinating the use of fishing ports and cooperating in exams in the offshore.The MMC general release on December 3, 2021 was held at the land doll -fish sales party at Hiratsuka Tama Saburo Fishing Port under such a group.On the day, the southwest wind was strong, and the swell entering the port in addition to the waves due to the headwind, but the MMC could navigate without any problems.

　Dr. Lee of the University of Tokyo Production Technology Research Institute said, "Originally developed wirelessly in anticipation of applications in the ocean, but developed to wire, knowing that this joint development is highly used in ports.It has been able to expand the range of products and have led to the development of more practical products. "

　Mr. Tsutomu Kobayashi, director of the Tokyo Kuei Business Promotion Office, said, "Initially, we had a port inspection in mind, but since the low center of gravity structure is adopted, even if it is a normal boat, it is likely to overthrow.In addition to the stability that is not a problem, there is a forward force that is as good as the wind pressure. In this case, it is possible to use it outside the port. "
