Resumen:
Una universidad coreana ha desarrollado el prototipo de un robot para eliminar medusas. Este robot navega y elimina las medusas automáticamente gracias a un sistema de localización que combina un GPS (sistema de posicionamiento global), una IMU (unidad de medición inercial) y una cámara para detectar las medusas. El robot de superficie no tripulado con cinta transportadora es impulsado por dos estructuras cilíndricas que utilizan motores de propulsión para moverse hacia adelante y hacia atrás y hacer giros de 360º. La universidad busca un socio para transferir la tecnología y continuar con la investigación y desarrollo para aplicar el robot en la industria.



Details

Tittle:
A Korean university is offering a technology of multi-agent autonomous surface robots for harmful jellyfish removal
Summary:
To solve serious problems caused by "jellyfish blooms", a university located in South Korea has developed a prototype of jellyfish removal robot system. The robot can autonomously navigate and remove jellyfish based on the localization system, which is the combination of a GPS (Global Positioning System), an IMU (Inertial Measurement unit) and a camera that can detect jellyfish. The university is seeking a partner for technology transfer or for further R-Y-D to apply it to industry.
Description:
Recent drastically overpopulated jellyfish due to environmental pollution, climate change and increased number of marine structures has caused enormous damage to fisheries industries, power plants, and ocean tourism.

The damage is estimated to be over 300M USD per year in South Korea. This problem has been reported in more than 14 countries and an effective solution is required.

For this reason, an R-Y-D team in the department of civil -Y- environmental engineering in a university located in South Korea has developed a jellyfish removal robot system. An unmanned surface robot with a mountable grinding part or a conveyor belt is buoyed by two cylindrical bodies that utilizes propulsion motors to move forward and reverse, as well as rotate 360 degrees. Furthermore, GIS (geographic information system)-based map data is used to specify the region for jellyfish extermination, which automatically calculates the path for the task. It then navigates autonomously using a GPS (Global Positioning System) receiver and an INS (inertial navigation system).

The robot system was extended to a multi-agent robot system composed of three prototypes to enhance the efficiency of jellyfish removal, and the leader-follower scheme is employed to control formation of the multiple robots. The multiple robots maintain a set formation pattern, while calculating its course to perform jellyfish extermination.

Before the removal work, a drone equipped with a camera flies to recognize jellyfish distribution over the ocean. The feasibility of the formation control and the performance of jellyfish removal were demonstrated through field tests performed in the southern coast of South Korea. The field test results show that three assembly robots operating at 4 knots (7.2km/h) disposes jellyfish at the rate of about 900kg/h.

The university wants to transfer its technology to an industry or cooperate with an industry that needs this technology. A partner who is willing to do further R-Y-D for commercialization is also welcomed because the university is open for international R-Y-D as well.
Advantages and Innovations:
- It is the country first development that includes prototypes of the robot, algorithms for autonomous navigation, vision-based jellyfish detection, and formation control.
- Using various sensors and control algorithms, it can be utilized for monitoring of ocean environment, preventing algae-proliferation, reconnaissance of coastal area, etc.
- There is no need for individual control of the robots. Only the leader robot requires the calculated path, and the other robots can simply follow in a formation by exchanging their location information via wireless communication. (ZigBee method)
- With the support of Korean government, the technology has been transferred to a company, who had a pilot service in Masan Bay located in the southern coast of Korea.
- The formation control technologies were used in the oil spill protection robot project in cooperation with Korea Coast Guard.

Partner sought

Type and Role of Partner Sought:
- Type of partner sought: company
- Specific area of activity of the partner: in the field of maritime, power plants or fishing industry
- Task to be performed: with its requirements, the partner company should be able to apply the transferred technology to its business. Also, if the partner company would like to do further R-Y-D with the university, it should be aware of international R-Y-D projects as well as its roles in the project.
