There is an auxiliary spring. The invention is used for unmanned underwater carrying.

Description

technical field [0001] The invention relates to a robotic jellyfish, in particular to a robotic jellyfish driven by a built-in cylindrical motor. Background technique [0002] The bionic unmanned underwater carrier robot is a mechanical system developed and designed with reference to underwater bionic prototypes (such as fish, turtles, etc.). It has the characteristics of high efficiency and quietness. Therefore, it has important military and commercial value, attracting more and more researchers to work in this area. Generally speaking, the propulsion forms of underwater bionic prototypes can be roughly divided into three forms: body caudal fin propulsion (BCF), pectoral fin propulsion (MPF), and jet propulsion (JP). From the perspective of machine bionics, based on BCF and MPF The mechanical system of the propulsion prototype has the disadvantages of complex structure and difficult control. On the contrary, the system based on the jet propulsion prototype has the characte...
