Document Type and Number:
WIPO Patent Application WO/2023/097770
Kind Code:
A1
Abstract:
The present application provides a bionic fishtail and a bionic robot fish. The bionic robot fish comprises a head, a fish body and a bionic fishtail, wherein the head is arranged at a head end of the fish body; the bionic fishtail is arranged at a tail end of the fish body; and the head is provided with a waterproof steering engine for driving the fish body and the bionic fishtail to swing periodically. The bionic fishtail comprises: a driving mechanism which is arranged at a tail end of a fish body and electrically connected to a waterproof steering engine; and a caudal fin, wherein the driving mechanism is connected to the caudal fin, and is used for driving the caudal fin to open so as to increase the stress area of the caudal fin in water, or for driving the caudal fin to close so as to reduce the stress area of the caudal fin in water. In the bionic fishtail of the present application, the shape of the caudal fin can be actively adjusted in one swing period of the bionic fishtail, such that the caudal fin has a large-angle opening and closing function in a swimming process, thereby improving the overall swimming speed of a bionic robot fish.
