Problems solved by technology

[0002] At present, the research on robotic fish at home and abroad is mainly focused on the bionic realization of caudal fin and long dorsal fin. The wave-generating mechanism of robotic fish body and fins is formed by multiple swing mechanisms, and each point of robotic fish motion waveform is composed of this series. These mechanisms are more complicated, or the mechanism control is more troublesome, and the flexibility of maneuvering is not enough, and the turning performance is not enough

Embodiment Construction

[0009] Further illustrate the present invention below in conjunction with accompanying drawing.

[0010] Refer to attached figure 1 with figure 2 , the undulating bionic robotic fish includes a robotic fish body consisting of a cylindrical shell 7, a rear sealing cover 5 and a front sealing cover 4, and hoops 8 are respectively fixed at both ends of the shell. In the illustration, the hoop 8 consists of two halves The circular ring is formed; the circumferential direction of the front and rear sealing covers is respectively provided with an O-shaped sealing ring 13, which is used for the sealing of the inner cavity of the robotic fish body. Two steering gears 3, a circuit board 1 and a power supply battery pack 11 are fixed in the housing 7, and the front sealing cover 4 has two axial stepped holes, and the two rotating shafts 2 pass through the two stepped holes respectively, and are placed in the stepped holes. The inner ring of the bearing 6 in the large hole is fastened...

Abstract

The invention discloses a fluctuated bionic robot fish, which comprises a main body formed by a cylinder frame, two sealing covers, and a robot fin fixing element, wherein the frame of main body contains two helms, control circuit board and battery used to power the machine; two sides of main body via fin fixing element, are connected to two fluctuated fins made from flexible material; the front sealing cover has two rods connected to the driving helm, via the vibration of helm, to make two rods as the vibration source of fluctuated fin; the vibration source, via flexible fluctuated fin, is transmitted backwards to form the traveling wave to push the robot fish. The invention has simple structure and lower noise.

Description

technical field [0001] The invention relates to a fluctuating bionic robot fish, in particular to a biomimetic squid, stingray and other fluctuating robotic fish without spines and side fins. Background technique [0002] At present, the research on robotic fish at home and abroad is mainly focused on the bionic realization of caudal fin and long dorsal fin. The wave-generating mechanism of robotic fish body and fins is formed by multiple swing mechanisms, and each point of robotic fish motion waveform is composed of this series. These mechanisms are relatively complicated, or the mechanism control is relatively troublesome, and the flexibility of maneuvering is not enough, and the turning performance is not enough. Contents of the invention [0003] The object of the present invention is to provide a wave bionic robot fish with simple, portable, maneuverable and flexible structure. [0004] The undulating bionic robotic fish of the present invention comprises a robotic f...
