Description

Technical Field

[0001] The present invention relates to the field of robot technology, in particular to a humanoid robot simulated skin and a temperature control system. Background Art

[0002] With the development of robotics, humanoid robots have made significant progress in anthropomorphic appearance and movements, but technical bottlenecks remain in the areas of touch and temperature perception. Existing humanoid robots generally use rigid shells or a single flexible material, lacking the ability to simulate temperature. This results in a "cold" feeling when humans interact with the robots, making it difficult to meet the demand for a natural interactive experience in scenarios such as medical care and childcare. For example, in medical rehabilitation scenarios, robots that can simulate human body temperature can enhance patient psychological acceptance and improve the effectiveness of rehabilitation training. In education, robots with body temperature feedback can more realistically simulate the touch of human teachers, enhancing the immersiveness of interactive teaching.

[0003] Some robots currently attempt to achieve temperature regulation through external heating devices, but these devices suffer from issues such as uneven temperature distribution, delayed response, and high energy consumption. Traditional heating methods with electric heating wires are prone to localized overheating, while liquid circulation systems suffer from complex piping layouts, low thermal efficiency, and a lack of adaptive capabilities to dynamically adjust to the environment. Therefore, developing an artificial skin system that combines a soft touch, precise temperature control, and environmental adaptability has become a key technical direction for improving the interactive performance of humanoid robots. Summary of the Invention

[0004] To solve the above-mentioned problems, the present invention proposes a humanoid robot simulated skin and temperature control system that uses a composite structure and intelligent temperature control technology to simulate human body temperature, solve the problem of lack of temperature feedback in existing robots, and improve the naturalness and functionality of human-computer interaction.

[0020] Preferably, when the skin surface temperature exceeds a preset threshold, the control module automatically cuts off the power supply of the heating module and starts a rapid heat dissipation mode of the heat exchange system.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] In medical care applications, the artificial skin features a soft, skin-friendly outer layer of silicone material, simulating the delicate touch of human skin. The inner layer integrates temperature control through a multi-layer composite structure. The internal temperature control layer 2 is embedded in a dense circulation pipe 6, surrounded by a phase change material 7 to create a temperature buffer zone. Temperature sensors 3 are evenly distributed in easily accessible areas to sense surface temperature changes in real time. The heating module 4, a flexible heating element, fits beneath the circulation pipe 6, ensuring even heat transfer to the outer layer. The overall structure balances flexibility and thermal efficiency.

[0032] The temperature control system coordinates the operation of various components through an intelligent control module. When temperature sensor 3 detects that the skin surface temperature is below the normal human body range, the control module automatically activates the heating element and adjusts the flow rate of the heat-conducting liquid 5 in the circulation pipe 6, rapidly raising the temperature through a dual heating mechanism. If the temperature exceeds a preset threshold, the system prioritizes heat dissipation through liquid circulation and activates the cooling module to assist in cooling when necessary. The control logic dynamically adjusts parameters based on environmental data to achieve precise temperature maintenance and smooth temperature transitions.

[0033] This embodiment was tested in a medical rehabilitation setting. When the robot is in contact with a patient, its skin surface temperature remains stable near human body temperature, creating a natural, gentle touch that effectively alleviates patients' resistance to cold equipment. The system is highly responsive, automatically adjusting to contact pressure and ambient temperature. Overheating was avoided during extended use, ensuring safety and comfort that meet medical care requirements, enhancing the user-friendly and professional nature of human-machine interaction.

[0034] Example 2

[0035] Designed specifically for child care scenarios, the simulated skin features a food-grade outer layer made of elastic and safe silicone, with a biomimetic texture treatment for enhanced realism. The internal temperature control layer 2 utilizes a lightweight design, with optimized spacing between the circulation pipes 6 to minimize material redundancy while ensuring uniform heat conduction. The phase change material 7 is a type that matches human body temperature, absorbing and releasing heat through a physical phase change process during temperature fluctuations, helping to maintain temperature stability. The heating module 4 utilizes low-power components to avoid excessive energy consumption during extended operation.

[0036] The temperature control system integrates an adaptive adjustment algorithm. The control module automatically learns and optimizes temperature regulation strategies based on children's contact habits and ambient temperature fluctuations. For example, in low-temperature environments, the system preemptively increases heating power to reserve heat. When frequent contact is detected, the system automatically reduces heating intensity to prevent local overheating. The overheat protection mechanism is combined with a voice reminder function. When the temperature approaches the upper limit, the robot will proactively prompt children to maintain an appropriate contact distance to ensure their safety.

[0037] In practical applications, the simulated skin demonstrates excellent temperature adaptability in child-friendly environments, quickly adjusting to a comfortable temperature range, whether in roomy indoor environments or low winter temperatures. The soft touch and stable temperature feedback are highly appreciated by children. The system operates stably during extended periods of care, without overheating or energy depletion issues. This effectively enhances the robot's companionship experience and safety, making it a reliable partner for children throughout their growth.

[0038] Example 3

[0039] The simulated skin used in education focuses on authentic interactive experiences and system stability. Its outer layer utilizes a highly elastic composite material to withstand frequent contact and slight compression. The internal temperature control layer 2 features a modular design for ease of maintenance and functional expansion. The circulation pipe 6 and heating module 4 are integrated through an integrated molding process to reduce contact thermal resistance and improve thermal conductivity. Seven layers of phase change material are evenly distributed throughout the temperature control layer, forming a three-dimensional temperature regulation network to ensure uniform surface temperature.

[0040] The temperature control system utilizes advanced closed-loop control technology. Temperature sensors collect real-time data and feed it back to the control module. A precise algorithm dynamically adjusts heating power and liquid circulation speed, achieving rapid response and maintaining stable temperature. To address the multi-person interaction in educational settings, the system can control the temperature of different areas. For example, independent temperature control units are installed in high-touch areas such as hands, ensuring precise local temperature control while minimizing overall energy consumption.

[0041] In teaching demonstrations and interactive experiments, the simulated skin demonstrated excellent performance. The skin's surface temperature can simulate different states, such as "warm" and "cool," depending on teaching needs, to aid students in understanding physical concepts. When multiple people touch the skin simultaneously, each zone's temperature control unit operates independently, maintaining stable temperatures in its own area without interfering with each other. The system maintains temperature accuracy and energy consumption within reasonable limits even after running for several hours, providing reliable temperature interaction support for educational robots and enhancing the liveliness and engagement of the teaching process.

[0042] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
