Abstract
Description
Technical Field
[0001] This application relates to the field of robotics, and more specifically, to a stealth flying robot. Background Technology
[0002] Bionic miniature flapping-wing flying robots are a new type of flying robot designed and manufactured based on bionic principles, mimicking the flight of birds and insects. Compared with fixed-wing and rotary-wing flying robots, bionic flapping-wing flying robots have unique advantages: they possess excellent flight flexibility and high lift, as well as flight stability and anti-interference capabilities. They can fly for extended periods with relatively little energy. The soft materials used to construct their wings ensure they will not harm people, making them safer and more suitable for human living environments. Furthermore, similar to seagulls and large birds, they are virtually silent during flight, providing better stealth.
[0003] Due to these outstanding advantages, biomimetic flapping-wing flying robots have broad application prospects in the civilian and defense fields. Currently, a variety of biomimetic micro flapping-wing flying robots have emerged, such as the B2 biomimetic bat robot, the large flying fox BionicFlyingFox developed by Festo, and the silver gull. However, although current biomimetic flapping-wing flying robots are silent when flying, there is currently no stealth biomimetic flapping-wing flying robot, and it is impossible to provide a stealth biomimetic flapping-wing flying robot.
[0004] Therefore, existing technologies still need improvement. Summary of the Invention
[0005] The purpose of this application is to provide a stealth flying robot to solve the problem that there is currently no stealth bionic flapping-wing flying robot.
[0006] To achieve the above objectives, the technical solution adopted in the embodiments of this application is as follows:
[0007] A stealth flying robot, comprising:
[0008] The flying robot itself;
[0009] A biconvex lens array film is disposed on the outer surface of the flying robot body. The biconvex lens array film has a biconvex lens array. The biconvex lens array film guides the light entering from the front to be emitted from the side through the biconvex lens array to achieve stealth.
[0010] According to the stealth flying robot described above, the biconvex lens array film is set as a PDMS film.
[0011] According to the stealth flying robot described above, the biconvex lens array includes multiple biconvex lenses, and multiple biconvex lens arrays are arranged.
[0012] According to the stealth flying robot described above, the spacing between adjacent biconvex lenses is set to 10-15 μm.
[0013] According to the stealth flying robot described above, the radius of curvature of the biconvex lens is set to 15-20 μm.
[0014] Based on the above-described stealth flying robot, the flying robot is configured as a flapping-wing flying robot, and the shape of the flying robot body is designed to resemble a biomimetic seagull.
[0015] According to the stealth flying robot described above, the stealth flying robot also includes:
[0016] Multiple sensors are installed inside the flying robot.
[0017] According to the stealth flying robot described above, the stealth flying robot also includes:
[0018] A control module is located inside the flying robot, and the output of the control module is connected to the input of the multiple sensors.
[0019] According to the stealth flying robot described above, the stealth flying robot also includes:
[0020] A power module is located inside the flying robot. The output terminal of the power module is connected to the input terminal of the control module to supply power to the control module.
[0021] According to the stealth flying robot described above, the power module includes a battery.
[0022] The beneficial effects of the stealth flying robot provided in this application are at least as follows:
[0023] This application achieves optical steerability for a flying robot by setting a thin film with a biconvex lens array on the outer surface of the robot body. When light enters this thin film, the arrangement of the biconvex lens array can cause the light to be refracted in a predetermined manner. This refraction can cause the light to bend when passing through the thin film (e.g., guiding light entering from the front to be emitted from the side) or be focused in a specific direction. By accurately designing the radius of curvature and arrangement of the biconvex lenses in the array, the path of the light can be controlled, making the object less obvious or completely disappearing into the background when viewed from a specific angle, thus achieving optical steerability for the flying robot. By applying the flying robot of this application, it is possible to approach targets more effectively and perform reconnaissance missions. Attached Figure Description

[0032] Bionic miniature flapping-wing flying robots are a new type of flying robot designed and manufactured based on bionic principles, mimicking the flight of birds and insects. Compared with fixed-wing and rotary-wing flying robots, bionic flapping-wing flying robots have unique advantages: they possess excellent flight flexibility and high lift, as well as flight stability and anti-interference capabilities. They can fly for extended periods with relatively little energy. The soft materials used to construct their wings ensure they will not harm people, making them safer and more suitable for human living environments. Furthermore, similar to seagulls and large birds, they are virtually silent during flight, providing better stealth.
[0033] Due to these outstanding advantages, biomimetic flapping-wing flying robots have broad application prospects in the civilian and defense fields. Currently, a variety of biomimetic micro flapping-wing flying robots have emerged, such as the B2 biomimetic bat robot, the large flying fox BionicFlyingFox developed by Festo, and the silver gull. However, although current biomimetic flapping-wing flying robots are silent when flying, there is currently no stealth biomimetic flapping-wing flying robot, and it is impossible to provide a stealth biomimetic flapping-wing flying robot.
[0034] For this purpose, please refer to Figure 1 , Figure 2 and Figure 3 This application provides a stealth flying robot, including a flying robot body 1 and a biconvex lens array film (not shown in the figure). The biconvex lens array film is disposed on the outer surface of the flying robot body 1. The biconvex lens array film has a biconvex lens array. The biconvex lens array film guides the light entering from the front to be emitted from the side through the biconvex lens array.
[0035] The biconvex lens array is an optical structure typically used to adjust and control the direction of light propagation. The biconvex lens array film is a thin film with a biconvex lens array, which also has the function of adjusting and controlling the direction of light propagation.
[0036] This embodiment uses a biconvex lens array film with a biconvex lens array on the outer surface of the flying robot body 1. When light enters this biconvex lens array film, the arrangement of the biconvex lens array can cause the light on the biconvex lens array film to undergo predetermined refraction. This refraction can cause the light to bend when passing through the biconvex lens array film (for example, guiding the light entering from the front to be emitted from the side) or be focused in a specific direction. By accurately designing the radius of curvature and arrangement of the biconvex lenses in the biconvex lens array, the path of the light can be controlled, so that when viewed from a specific angle, the object appears less obvious or completely disappears into the background, thereby achieving optical cloaking of the flying robot. By applying the flying robot of this embodiment, it is possible to approach the target better and carry out reconnaissance missions.
[0037] In addition, the special design of the biconvex lens array can enhance the optical effect, such as preventing the light from being reflected or scattered within certain wavelength ranges, thereby visually reducing the visibility of the object. This technology is particularly suitable for adjusting light of specific wavelengths to achieve a more precise invisibility effect.
[0038] Optionally, in one embodiment, the biconvex lens array includes a plurality of biconvex lenses, the plurality of biconvex lens arrays being arranged such that each biconvex lens has two opposing convex surfaces protruding from the surface of the biconvex lens array film.
[0039] Optionally, in one embodiment, the spacing between adjacent biconvex lenses is set to 10-15 μm. In this embodiment, by setting the spacing between biconvex lenses to 10-15 μm, the biconvex lens array is closely arranged in the biconvex lens array film. This close arrangement helps to minimize the possibility of light being reflected from the surface of the biconvex lens array film, and the invisibility effect is achieved by controlling the refraction direction of the light.
[0040] Optionally, in one embodiment, the radius of curvature of the biconvex lens is set to 15-20 μm.
[0041] Optionally, in one embodiment, the biconvex lens array film can be set as a PDMS (polydimethylsiloxane) film. Optical stealth is not only achieved by controlling light refraction, but also requires consideration of surface reflection management. PDMS material itself has a low refractive index and less optical reflection, which helps to reduce the light reflected from the surface of the biconvex lens array film, thereby reducing the possibility of the object being detected, so as to further improve the stealth effect.
[0042] It is worth noting that achieving optical invisibility with PDMS films usually requires precise design and experimental verification. Researchers use optical equipment in the laboratory to test the effect of the film, such as observing the visibility of objects at different angles and under different lighting conditions using lasers or white light sources, in order to verify and optimize the design of the biconvex lens array.
[0043] The fabrication steps of the biconvex lens array film are as follows: First, prepare a mold with a biconvex lens array. The mold can be prepared by photolithography or manufactured by 3D printing. Then, mix the PDMS prepolymer and crosslinking agent in a specific ratio, stir and degas under vacuum conditions, and pour the mixture into the mold. Next, place the mold containing the PDMS prepolymer and crosslinking agent into an oven or at room temperature for curing. Finally, peel the PDMS film formed by curing the PDMS prepolymer and crosslinking agent from the mold to obtain the biconvex lens array film.
[0044] Optional, see below Figure 1 and Figure 2 In one embodiment, the flying robot is configured as a flapping-wing flying robot. Based on the above-mentioned stealth capability achieved by the shape of the flying robot, this embodiment further enhances the stealth capability by configuring the flying robot as a flapping-wing flying robot. Since flapping-wing flying robots are silent when flying, they can achieve better stealth capabilities, thereby enabling better concealment and approach to the target area.
[0045] Optional, see below Figure 1 and Figure 2 In one embodiment, the shape of the flying robot body 1 can be set as a biomimetic seagull shape.
[0046] Optionally, in one embodiment, the stealth flying robot further includes multiple sensors (not shown in the figure), all of which are disposed within the flying robot body 1.
[0047] Optionally, in one embodiment, the stealth flying robot further includes a control module (not shown in the figure), which is disposed inside the flying robot body 1, and the output terminal of the control module is connected to the input terminals of the plurality of sensors respectively.
[0048] Optionally, in one embodiment, the stealth flying robot further includes a power module (not shown in the figure), which is disposed inside the flying robot body 1. The output terminal of the power module is connected to the input terminal of the control module to supply power to the control module.
[0049] Optionally, in one embodiment, the power module may include a battery.
[0050] In summary, this application provides a stealth flying robot, comprising a flying robot body 1 and a biconvex lens array film. The biconvex lens array film is disposed on the outer surface of the flying robot body 1. The biconvex lens array film has a biconvex lens array, which guides light incident from the front to be emitted from the side. By disposing of a biconvex lens array film with a biconvex lens array on the outer surface of the flying robot body, when light enters this biconvex lens array film, the arrangement of the biconvex lens array can cause the light on the biconvex lens array film to undergo predetermined refraction. This refraction can cause the light to bend when passing through the biconvex lens array film (e.g., guiding light incident from the front to be emitted from the side) or be focused in a specific direction. By accurately designing the radius of curvature and arrangement of the biconvex lenses in the biconvex lens array, the path of the light can be controlled, so that when viewed from a specific angle, the object appears less obvious or completely disappears into the background, thereby achieving optical stealth of the flying robot. By applying the flying robot of this application, it is possible to approach targets more effectively and conduct reconnaissance missions. In addition, the special design of the biconvex lens array can enhance the optical effect, such as preventing the light from being reflected or scattered within certain wavelength ranges, thereby visually reducing the visibility of the object. This technology is particularly suitable for adjusting light of specific wavelengths to achieve a more precise invisibility effect.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
