Kazakh engineering students developed a transparent plastic jacket of a bionic jellyfish robot, which can visualize the internal structure and tail propellers like jellyfish tentacles. This special-looking robot is called "bionic jellyfish underwater robot." This year's "Intellectual Property Cup" won the first prize in the invention innovation competition. The robot adopts bionic technology, and the appearance of bionic jellyfish reduces the disturbance to marine life. It can complete the close-range monitoring of fish schools and the monitoring of complex or sensitive waters. At present, many underwater unmanned robots have some shortcomings, such as weak battery life, high demand for energy, unable to achieve long-term fixed-point control of fixed areas, robots relying on propeller propulsion are noisy, and are easily disturbing fish Exposure targets, poor concealment, etc. The bionic jellyfish robot developed by 3 junior students of the School of Marine Engineering, Harbin Engineering University based on bionics effectively made up for the above shortcomings. The robot consists of three tank sections, and the first ballast water tank is used to control the floating state of the robot. The camera in the middle is an important part of the robot, and it is the eyes of the robot underwater. The power propulsion system at the rear is equipped with a controller, a steering gear, a battery, and a high-torque, low-speed motor. The controller is the brain of the "jellyfish", and all systems are controlled by the controller. The battery provides power for the complete system, and the motor connects the four "tentacles" of the "jellyfish" through the transmission device to provide power to the robot.
