[0052] Example 2

[0053] See also Figure 4 Embodiment 2 of the present invention provides a method for constructing a muscle-driven micro underwater robot, comprising the following steps:

[0054] S1. Obtain bullfrog hind limb muscle tissue by dissecting bullfrog hind limbs;

[0055] S2. Designing a high-elasticity driving fin structure according to the bullfrog hind limb muscle tissue; obtaining a first composite material by 3D printing according to the high-elasticity driving fin structure; and wrapping a second composite material on the surface of the first composite material to obtain a high-elasticity driving fin;

[0056] S3, placing the microcontroller at the tail of the robot;

[0057] S4, applying the bullfrog hind limb muscle tissue to the surface of the high elastic driving fin by setting a connection strategy; inserting a plurality of silver needles into the set excitation positions of the bullfrog hind limb muscle tissue; connecting the silver needles to the microcontroller through wires;

[0058] S5, setting a circuit board packaging film outside the microcontroller, and packaging the microcontroller by setting a packaging strategy;

[0059] S6. Encapsulate the microcontroller and the highly elastic driving fins through a highly elastic shell membrane; and inject Ren's solution into the interior of the highly elastic shell membrane through the injection hole.

[0060] In this embodiment, in step S1, the bullfrog hind limb muscle tissue is obtained by dissecting the bullfrog hind limb;

[0061] Specifically, fresh bullfrog hind limbs are dissected to obtain the required bullfrog hind limb muscle tissue.

[0062] In this embodiment, in step S2, a high elastic driving fin structure is designed according to the bullfrog hind limb muscle tissue; a first composite material is obtained by 3D printing according to the high elastic driving fin structure; a second composite material is wrapped on the surface of the first composite material to obtain a high elastic driving fin;

[0063] Specifically, the double-layer high-elasticity driving fin structure is designed according to the muscle shape. The inner layer is made of a material with good elasticity and a certain rigidity for 3D printing. The outer layer is made of a suitable high-elasticity material, and a layer of high-elasticity material is coated on the surface of the driving fin through surface functionalization methods such as coating and synchronous light curing to form a composite high-elasticity driving fin.

[0064] In this embodiment, in step S3, the microcontroller is placed at the tail of the robot;

[0065] Specifically, a micro integrated controller is integrated into the tail of the micro robot. The micro controller includes: a micro battery pack, a micro Bluetooth device, a micro control chip, a peripheral film and several components (such as a temperature sensor). The Bluetooth module is used for remote control of the robot, and the micro battery pack is used to power the control chip and the Bluetooth module and generate an excitation signal for muscle control.

[0066] In this embodiment, in step S4, the bullfrog hind limb muscle tissue is attached to the surface of the high elastic driving fin by setting a connection strategy; a plurality of silver needles are inserted into the set excitation positions of the bullfrog hind limb muscle tissue; the silver needles are connected to the microcontroller through wires;

[0067] Specifically, the muscle tissue is glued to the front end of the highly elastic driving fin with bio-affinity glue, and the surface of the driving fin is stretched to generate a large elastic deformation to store energy, and the energy is released to generate a driving force. Silver needles are placed at different parts of the muscle tissue according to needs, and the silver needles are connected to the microcontroller through wires to transmit excitation signals.

[0068] In this embodiment, in step S5, a circuit board packaging film is provided outside the microcontroller, and the microcontroller is packaged by setting a packaging strategy;

[0069] Specifically, the microcontroller is packaged by a circuit board packaging film to avoid short circuit caused by contact with external liquid or internal Ringer's fluid in an underwater environment.

[0070] In this embodiment, in step S6, the microcontroller and the highly elastic driving fin are packaged by a highly elastic shell film; and Ren's solution is injected into the interior of the highly elastic shell film through the injection hole.

[0071] Specifically, the controller and the highly elastic driving fins are encapsulated with waterproof glue through a flexible shell film, and Ren's solution is injected into the robot film through the injection hole.

[0072] In this embodiment, Figure 5 As shown in the figure, under the stimulation of various electrical signals (including auxiliary signals, pulse signals and duty cycle control), the robot can accurately apply electrical excitation to multiple muscle tissues, and these muscle tissues show diverse contraction patterns due to stimulation of different positions and intensities. This patterned muscle activity enables the robot to perform multi-posture, large-scale displacement movements, thereby achieving rapid forward propulsion, flexible left and right turns, and precise sinking and floating control. For example, when only one side of the driving fin is electrically stimulated in the vertical direction, the robot can successfully complete the turning action; if the fins on both sides are stimulated in the inclined direction at the same time, it can be precisely controlled to achieve sinking and floating movements.

[0073] The pH sensor can be used to monitor the pH changes of the nutrient solution during the operation of the robot. Through feedback control, the pH of the Ren's solution is maintained between 7.2-7.4, so that the muscle cells maintain the best working environment; the temperature sensor is used to monitor the operating temperature of the robot, and the control panel is used to maintain the appropriate temperature to maximize the life of the muscle tissue. When the muscle tissue loses its activity, the outer film glue can be dissolved by a sol, and new muscle tissue can be quickly dissected for replacement, and then glued with glue. The drive source has strong replaceability.

[0074] In this embodiment, researchers can arbitrarily replace muscle tissue, flexible leg structure and position distribution, electrical signal excitation position distribution, etc. according to actual needs to regulate the overall motion performance of the robot.

[0075] In a possible embodiment, a specific construction example is provided as follows:

[0076] T1, dissect the bullfrog hind limbs and obtain the gracilis major muscle;

[0077] T2, designing a highly elastic drive fin structure based on muscle tissue, using F127DA material to implement integrated light-curing 3D printing technology to complete the manufacturing process. Subsequently, Ecoflex material is used and evenly coated on the surface of the structure to form a gel state, and finally a highly elastic drive fin is constructed.

[0078] When the robot moves, the controller first stimulates the muscles to contract slowly, driving the highly elastic drive fins to produce elastic deformation and store energy. After the energy is stored, the stimulation stops and the rapid release generates a strong driving force. This high elasticity is crucial to extending the service life of the robot when it is subjected to cyclic loads. At the same time, it also enables the robot to withstand large strains, thereby effectively improving its motion performance.

[0079] T3, a single microcontroller with Bluetooth, battery and sensor is installed at the tail of the robot to avoid damage to the controller when the muscle contraction enables the robot to swim;

[0080] T4. Glue the muscle tissue to the front end of the high-elastic driving fin with bio-affinity glue, place silver needles at different parts of the muscle tissue as needed, and connect the silver needles to the controller through wires.

[0081] T5. Use film and glue to encapsulate the controller to avoid short circuit when it comes into contact with Ren's solution;

[0082] T6. Encapsulate the controller and the highly elastic driving fins with waterproof glue through a flexible shell film, and inject Ren's solution into the robot film through the injection hole.

[0083] In summary, the present invention obtains bullfrog hind limb muscle tissue by dissecting the bullfrog hind limb; designs a high-elasticity driving fin structure according to the bullfrog hind limb muscle tissue; obtains a first composite material by 3D printing according to the high-elasticity driving fin structure; wraps a second composite material on the surface of the first composite material to obtain a high-elasticity driving fin; places a microcontroller on the tail of the robot; applies the bullfrog hind limb muscle tissue on the surface of the high-elasticity driving fin by setting a connection strategy; inserts a plurality of silver needles into the set excitation positions of the bullfrog hind limb muscle tissue; connects the silver needles to the microcontroller through wires; sets a circuit board packaging film outside the microcontroller, and packages the microcontroller by setting a packaging strategy; packages the microcontroller and the high-elasticity driving fin through a high-elasticity shell film; and injects Ren's solution into the high-elasticity shell film through an injection hole. The micro underwater robot constructed by the present invention innovatively uses bullfrog hind limb muscles as the driving source, and uses a composite double-layer flexible material for the robot driving fin and shell film, so that each part of the robot can be subjected to large displacement passive telescopic deformation, which greatly avoids the occurrence of structural failure due to collision. At the same time, it also has the advantages of life-like characteristics, low noise, high structural reliability, high energy density, etc., which are not available in existing rigid drives (such as electromagnetic drives, memory metal drives, etc.) and rigid structure robots. In addition, the driver uses the bullfrog muscles obtained by dissection as the driving source, which is simple to replace and has high sensitivity. The activity of the isolated muscle can be maintained by Ren's solution, and the raw materials are easy to obtain without special energy supply equipment, which greatly reduces the size of the robot, making the robot have the characteristics of high energy density and low cost.

The method of the present embodiment can also be applied in a distributed scenario and completed by multiple devices cooperating with each other.
