Abstract

The invention discloses a jellyfish imitation robot and a control method of the jellyfish imitation robot. The jellyfish imitation robot comprises a hemispherical soft shell, a plurality of elastic pull rods, a plurality of shape memory alloy wires and a tail fin, wherein the elastic pull rods are supported on the inner side of the hemispherical soft shell. The tail fin comprises tail fin rings and fin plates, wherein the fin plates stretch out from the tail fin rings. One ends of the shape memory alloy wires are connected with connecting parts of the elastic pull rods, and the other ends of the shape memory alloy wires are connected with the tail fin rings. Shrinkage or stretching of the shape memory alloy wires is controlled to enable the hemispherical soft shell to shrink or stretch to acquire power and steering of the jellyfish imitation robot, the jellyfish imitation effect is generated, and then the jellyfish imitation robot moves, and the shape memory alloy wires drive the tail fin to deflect to achieve steering. The jellyfish imitation robot is simple in structure and easy to control.

Description

technical field [0001] The invention relates to people in the field of machines, in particular to a bionic robot and a control method thereof. Background technique [0002] With the needs of marine protection and underwater reconnaissance, people pay more and more attention to underwater robots. These robots will show their talents in underwater reconnaissance, surveillance of ships and submarines, detection of chemical spills, and monitoring of fish migration. . Jellyfish is an ideal invertebrate, relying on muscle fibers to control the contraction and expansion of the inner cavity to inhale and eject water flow, thereby generating thrust to move the jellyfish along the axial direction of the body. At present, it has received high attention as a bionic object at home and abroad. However, the current imitation jellyfish robot has a complex structure, high cost and is difficult to control when swimming. [0003] Therefore, a new technical solution is needed to solve the ab...
