Description

technical field

[0001] The invention relates to the field of bionic robots, in particular to a golden jellyfish imitation robot based on a six-bar mechanism. Background technique

[0002] The golden jellyfish moves in the water with the help of water flow. Through the method of water jet propulsion, some special muscles expand and then quickly retract to expel the water in the body. Driven by the reaction of the water flow, it achieves forward swimming, turning and other propulsion behaviors. .

[0003] Chinese patent 201410403982.9 discloses a robotic jellyfish driven by a built-in cylindrical servo motor. The jellyfish can achieve bionic propulsion in water through the hem and lift of the multi-joint arm, but the structure is complex, the stability is not high and it is difficult to control; Chinese patent 201510519863.4 discloses a jellyfish-type bionic robot. The robot adjusts the amount of water in and out through the water tank to achieve the purpose of floating and d...
