Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0026] like figure 1 , figure 2 , image 3 As shown, the airtight mechanical transmission type machine jellyfish of the present invention comprises: a cavity shell 2, a head shell 1 arranged on the cavity shell 2, an internal skeleton, a power transmission mechanism, a connecting rod actuator, The power source on the internal skeleton, the control circuit board, the power supply unit, and the elastic latex skin arranged on the connecting rod actuator. The head shell 1 is installed on the cylindrical upper section of the cavity shell 2 through an O-shaped sealing ring 22 and screws. Twelve screws were used for fastening; the elastic latex skin was used to simulate a soft cavity. The cavity shell 2 and the head shell 1...

Abstract

The invention discloses a closed mechanical transmission type machine jellyfish which comprises a cavity outer shell, a head outer shell, an internal framework, a power transmission mechanism, a connecting rod actuating mechanism, a motive power source, a control circuit board, a power source device and an elastic latex shuck, wherein the head outer shell, the internal framework, the power transmission mechanism and the connecting rod actuating mechanism are arranged on the cavity outer shell, the motive power source, the control circuit board and the power source device are arranged on the internal framework, and the elastic latex shuck is arranged on the connecting rod actuating mechanism. The contraction and the expansion of the cavity formed by the connecting rod actuating mechanism and the elastic latex shuck are achieved through the output motion of a steering engine so that a jetting pushing mode of a biological jellyfish can be simulated. The closed mechanical transmission type machine jellyfish can offer an experiment platform for researching hydrodynamics, a swimming mechanism and a control method of jellyfish motion and can be used for science popularization education and exhibition.

Description

technical field [0001] The invention relates to an airtight mechanical transmission type robotic jellyfish. Background technique [0002] The bio jellyfish has a smooth and graceful movement performance. From the perspective of engineering technology, if we can use the existing mechanical, electronic, computer, control and other means to develop a set of bionic robots that imitate the movement of jellyfish, it will be of great significance both in theory and in practice. [0003] The stability and flexibility of jellyfish swimming have brought inspiration to people for bionics. Biomimetic research based on jellyfish has gradually emerged, but currently it is mainly focused on micro-sized jellyfish-like robots based on smart materials. Bressers and others from Virginia Institute of Technology in the United States have produced an underwater autonomous robot "JetSum" based on jellyfish, which uses a shape memory alloy (SMA, Shape Memory Alloy) as a propulsion mechanism. In a...
