Two innovative high-tech application solutions, including an unmanned aerial vehicle (UAV) and an autonomous underwater vehicle (AUV) towards smart city development by the Navy Academy have won prizes at the 9th Provincial Technical Innovation Contest (2020-2021).
UAVs for search and rescue
A team of the Navy Academy and PhD. Phung Manh Duong, University of Technology Sydney have proposed the solution of UAVs for automatic monitoring, warning, search and rescue towards smart city development of convenience and security with modern technology infrastructures. The solution won the second prize at the 9th Provincial Technical Innovation Contest.

Lieutenant Colonel Hoang Van Truong, the team leader said the system contains an UAV equipped with IoT devices to add features of supervision, warning and response in emergency cases to protect residents and tourists for tourism development. The autonomous drones also employ a host of advanced technologies that allow them to carry out their missions without human intervention, such as computer vision, artificial intelligence and thermal sensors which can provide critical support to search and rescue operations, including dropping floatation devices, first aids, etc.; transmitting data and images.
The creators came up with the idea in 2018. However, they had to work on it online due to Covid-19. An UAV is considered as a vital approach to smart city development with such features as fast response, automation and telecommunication support. The solution and intensive research have been applied and implemented in Sydney (Australia), Hanoi and Khanh Hoa. The solution seeks to support the monitoring, signaling, patrol and search for hypothetical targets.
Development of autonomous underwater vehicles
An autonomous underwater vehicle (AUV) is a robot that travels underwater for civil and military applications such as search and rescue; seafloor and shipwreck exploration; archaeology, underground construction and many other applications. AUVs normally use ultrasonic waves to transmit images, but ultrasonic waves are also limited underwater, so a wire is needed to connect AUVs to the Wi-Fi system. The application of IoT technology reduces the wiring, thereby effectively promoting the control of AUVs. Therefore, Major, PhD. Pham Van Tuan (Naval Academy) proposed the solution "Application of IoT technology, Fuzzy logic and extended Kalman filter in small-sized AUV control", which has won the third prize in the recent contest.
The AUV is designed to optimize hydrodynamics, small and compact with 4 propulsion engines, fitted with scanning sonars, cameras, lights, sensors, Wi-Fi, etc. Its main mission is to explore the seabed, collect information on substrates and seafood resources for a nautical chart; combined with UAVs to patrol and monitor specified underwater areas and collect real-time data. The combination of AUVs and UAVs for underwater surveillance of the sea and bay estuaries is considered among the latest approaches in Vietnam.
According to Major Pham Van Tuan, the design and manufacturing of AUVs begun in 2008. He has produced 3 different types of AUVs. The AUV jointly created by Pham Van Tuan and his colleagues was tested and recognized abroad in 2018 and granted a patent by the Russian Federation. He is cherishing using the robot for fishing guidance and marine rescue device development in the coming time.
