A golden jellyfish imitation mechanism based on crank slider

Abstract

A golden jellyfish mechanism based on a crank slider comprises a crank slider mechanism, a frame, a leg mechanism and a collar. The crank slider mechanism comprises a crank, a connecting rod and a slider. One end of the crank is connected with one end of the connecting rod through a hinge, the other end of the crank is connected with the frame through a hinge, and the other end of the connecting rod is connected with the slider through a hinge. The machine base is a multi-sliding groove machine base, and a plurality of hinge bases are evenly distributed on the machine base, and each hinge bases is connected with a leg mechanism through a hinge; The leg mechanism comprises a first lever, a second lever, a third lever, a fourth lever, a fifth lever, a sixth lever, a seventh lever, an eighthlever and a long cylindrical pin shaft; The collar is nested in the sliding groove of the first lever and is connected to the first lever through a movable pair. The invention has the characteristicsof less required driving, light structure quality, low manufacturing cost, controllable moving speed and flexible obstacle avoidance, and is suitable for river water environment monitoring, seabed resource exploration and other fields.

Description

technical field [0001] The invention relates to the field of bionic mechanisms, in particular to an imitation golden jellyfish mechanism based on a crank slider. 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 201120541791.0 discloses a multi-functional underwater operation robot device. The robot device realizes underwater walking and ups and downs through a crawler drive device and a sink-float device. Using underwater large-scale and long-term motion; Chinese patent 201410403982.9 discloses a robotic jellyfish driven by an embedded cylindrical servo motor. Complex, unstable and difficult to control. [0004] An innovative invention design based on a crank s...
