Embodiment
[0033] The controllable robot based on the photosensitive intelligent composite material provided by this embodiment, such as figure 1 As shown, it includes a bionic fish main body 1 and an illuminating device 2 arranged on the bionic fish main body. The main body 1 of the bionic fish adopts the bionic structure of the deep-sea short-nosed lionfish, which includes a trunk 11, a pair of main fins 12 with the same structure and a pair of auxiliary fins 13 with the same structure that are symmetrically arranged on both sides of the trunk 11 from front to back, and The caudal fin 14 that is connected with the trunk rear end. The lighting device 2 is used to provide lighting for the two main fins and the two auxiliary fins.
[0034] Such as figure 1 As shown, the section of the torso 11 along the length direction is an inverted trapezoidal structure, and a triangular fish head extends from the front end thereof. The plane shape of the tail fin 14 is similar to the trunk, and i...

The invention discloses a controllable robot based on a photosensitive intelligent composite material. The controllable robot comprises a bionic fish body and a lighting device arranged on the bionic fish body. The bionic fish body comprises a trunk, a pair of main fins of the same structure, a pair of auxiliary fins of the same structure and a tail fin connected with the rear end of the trunk, wherein the main fins and the auxiliary fins are sequentially and symmetrically arranged on the two sides of the trunk from front to back. The main fins and the auxiliary fins are of a plate-shaped structure and are in a wing shape. The lighting device is used for providing lighting for the two main fins and the two auxiliary fins; the body is made of a non-hydrophilic material; the main fins, the auxiliary fins and the tail fin are made of an asymmetric double-layer composite material composed of a hydrogel photosensitive material and a thermal expansion material, and the hydrogel photosensitive material faces a light source of the lighting device. The controllable robot based on the photosensitive intelligent composite material is high in illumination responsivity, can achieve directional driving and turning on the water surface by means of natural light or an artificial light source, can serve as a driving mechanism for underwater environment monitoring, and can be loaded with a camera and other devices to achieve underwater environment monitoring.
Description
technical field [0001] The invention belongs to the field of robots and relates to a controllable robot driven by a photosensitive intelligent material. Background technique [0002] Bionic robotic fish is a type of robot that imitates fish in structure and movement, and is mainly used to monitor the underwater environment. In recent years, the research results of new bionic robot fish have been emerging, and based on different driving methods, the tail fins are driven to swing according to predetermined rules, so as to swim in the water. These drive methods include motor drive, hydraulic or pneumatic drive, shape memory alloy (SMA) drive, dielectric elastomer (DEs) drive and ion polymer metal composite (IPMC) drive, etc. [0003] However, there are certain problems in the driving methods given above. For example, the bionic robot fish driven by the motor generally adopts a rigid structure with multi-joint transmission, which is complicated in structure, and the noise and v...
