As the saying goes, the sky is wider than the ocean. But compared to the drones in the sky, the unmanned ships in the ocean may have a broader application prospect.
Speaking from the recent $14 million financing
Saildrone, based in Alameda, Calif., recently received $14 million in Series A financing, a company founded in 2012 that uses an automated unmanned fleet to provide real-time ocean data collection. This round of investment is dominated by Social Capital, Capricorn Investment Group and Lux ​​Capital. This is also the first time the company has accepted external venture capital.
Wind powered unmanned vessels developed by Saildrone are able to collect global ocean data. This technology has a wide range of applications, such as the patrol coast border, tracking global warming marker reference - ocean acidification, early detection of oil spills, following marine life. Compared to traditional vessel schemes, unmanned vessels can automatically collect data in wide seas at low cost and around the clock. Saildrone uses only wind energy to sail at sea speeds of 3-5 knots.
Each unmanned boat can provide a fixed or parade mode according to the research task. The ship has customized sensor satellites to transmit the detected data to the land. Through API distribution, the company is constantly striving to integrate new detection capabilities into the Unmanned boat. Customers can use their computers and phones/tablets to manipulate or visualize real-time data through a corporate client, allowing the Saildrone to reset tasks and measure them in real time with higher resolution. Basically, it controls all the actual operations, starting from the dock, returning to the air, and navigating autonomously on busy waterways.
In addition to marine information collection research, the Saildrone unmanned ship has potential application prospects in terms of material placement, personnel search and rescue, patrol monitoring, and communication.
Richard Jenkins, founder and CEO of Saildrone, said: "We are working hard with like-minded investors, mission-oriented and professionally experienced people to collaborate on innovative hardware and big data processing."
Saildrone CEO Richard Jenkins: Obsessed with nautical technology since childhood
Richard Jenkins was a nautical fan since childhood. He sailed on the south coast of England from an early age and wanted to design some fantastic installations. He spent ten years researching carbon fiber wind turbines, breaking the speed record of wind turbines at a speed of 126.1 miles per hour on the dry river bed of Ivanpah Lake in Nevada in 2009. Immediately, British engineers used the technology on the Saildrone unmanned boat, and its special tail-controlled free-rotating wing allowed it to travel long distances, built and designed in such a way that the worst weather conditions would not cause a shipwreck.
Before the measurement device was put on board, in 2013, the unmanned ship began a “proof of concept verification†from San Francisco to Hawaii. According to the company, the ship has sailed 60,000 nautical miles in the Pacific Ocean, the Atlantic Ocean, the Bering Sea and the Gulf of Mexico.
Jenkins said: "The data collected by Saildrone not only provides a better understanding of the ocean, but also an in-depth study of the processes that affect the entire human race, such as weather, fish resources, ocean acidification and climate change. Understanding the speed of these processes and their changes, for us The economy is related to survival."
The application of marine unmanned vessels is promising, and the broader than the ocean is the wisdom of human beings and the exploration of the world, making the world a better decision.
So how to realize the unmanned ship
Unmanned ship technology involves many aspects such as hydrodynamics, autonomous decision-making, automatic control, signal processing, network communication, and sensor technology, and has high technical difficulty. Unmanned ships want to have stable navigation capabilities and the ability to cope with unexpected situations in complex and dangerous sea areas. It is necessary to monitor their equipment's operating conditions, sense external information, make correct decisions and strictly enforce them. These operations rely on sensor systems that interact with the outside world, high-level autonomous navigation systems, precise automatic control programs, and stable and fast network communication technologies.
The sensor system, like the eyes and ears of the unmanned ship, transmits the processed and heard external information processing to the brain of the unmanned ship - the autonomous navigation system, the autonomous navigation system based on the dynamic chart and weather forecast, combined with the sensor The feedback real-time information gives decision-making instructions such as route and speed, and transmits the decision-making command to the automatic control program. The automatic control program adjusts the appropriate thrust of the rudder propeller in strict accordance with the decision-making command to complete the autonomous navigation. At the same time, the unmanned ship also needs to have the mode switching function independently selected, which can be autonomously switched in autonomous navigation, remote control, failure protection and other modes to ensure the safety of the unmanned ship.
Unmanned ship R&D is popular and controversial
The British Rolls-Royce company recently announced its "Advanced Unmanned Ship Application Development Program" (AAWA) project. Mikael Makinen, president of the company's ship business, said: "The unmanned ship is the future of the shipbuilding industry. Smart ships are as disruptive as smart phones and will revolutionize the design and operation of ships."
International Ship Network reported that Jouni Saarni, development manager of the Collaborative Research Center of the School of Economics at the University of Turku, said: "Remote and unmanned vessels may redefine the role of the ship industry and industry players, for shipping companies, shipbuilders and ship systems. Suppliers, as well as other areas, especially technology companies in the automotive industry, have an impact."
Jonne Poikonen, Senior Research Fellow at the Technical Research Center of the University of Turku, and Dr. Mika Hyvnen, Senior Research Fellow at the Tampere University of Technology, are co-leaders of the technical research of the project. JonnePoikonen said: “The technology needed to implement remote and unmanned ships is there – the sensor technology required is well-established and commercially available; the algorithm required for a strong decision support system – the ship’s “virtual captain†"- Not too far away. The challenge is how to best integrate these technologies into the ship's environment cost-effectively."
Recently, South Korea has new trends in unmanned ships. According to the China Ship Report, relevant Korean authorities have announced that they will focus on promoting the development of driverless driving and developing a “general joint platform†technology project, which is crucial for the development of drones, driverless cars and unmanned vehicles. common technology. It is reported that in the past four years, the Korean government has invested 284 billion won (about 241 million US dollars) in the driverless related field. In the future, South Korea will also promote the independent development of land, air and sea autonomous technologies.
Although the unmanned ship technology is improving day by day, its ultimate realization still cannot circumvent the increasingly prominent ethical issues. As a series of questions raised when people face unmanned vehicle technology – do driverless cars choose to save five or one person in the face of “tram problem� Should priority be given to protecting passengers in the car or pedestrians and vehicles in the accident? Who should be legally responsible for the upcoming driverless car accident, is it the owner, the manufacturer or the programmer? Under what circumstances does a driverless car be allowed to violate traffic regulations? At the same time, in the past two months, three serious car accidents in driverless cars have undoubtedly poured cold water on the unmanned technology that is rushing in the capital market.
Surface unmanned vessels also need to face similar problems. In addition to meeting the Convention on Maritime Collision Avoidance, operator training and the division of responsibilities after an accident are still a problem that plagues researchers and regulators. I believe that in the near future, unmanned ships will carry human wisdom and hope to the distance.
According to the China Ship Report, some unmanned ship technologies are mature and practical applications, such as environmental sensing technology, communication and navigation technology, condition monitoring and fault diagnosis technology, but some technologies lack verification in real environments. Such as energy efficiency control technology, route planning technology, safety early warning technology, autonomous navigation technology. Therefore, it can be said that the unmanned ship is still in a rapid development stage and is not yet fully mature. The development of intelligent technology in the next 10-20 years will determine the face of unmanned ships. Industry experts said that in addition to the above key technologies, automatic berthing, offshore, independent maintenance, automatic cleaning, automatic replacement of equipment components, self-protection and other aspects also need intelligent development.
Beyond technology, the commercialization of unmanned ships is also economically and safely confusing. Although some developers have strongly claimed that the construction cost, labor cost and fuel cost of unmanned ships will be greatly reduced compared with conventional ships, some shipping companies believe that unmanned ships will add many remote control systems and require new automation. Equipment, also need to establish a new shore-based remote control center, redesign the operation plan, train the staff, and the added cost will exceed the cost that the unmanned ship may reduce.
The developers of unmanned ships also said that most of the current maritime accidents are caused by human factors such as crew negligence and improper operation. In theory, the application of driverless technology will reduce such accidents by two-thirds. Currently, they are working on practical examples of driverless technology in various fields and ensuring that unmanned ships are at least as safe as current ships. (Comprehensive finishing)
