摘要

在本文中,我们介绍了一种创新方法,用于生成具有与人类相似热特征的机器人脸部,并为假肢或机器人手部配备逼真的温度分布。这种方法增强了通过红外摄像机对机器人的探测,促进了人类与机器人之间更自然的互动。这种方法将温度调节系统集成到人造皮肤中,从人体通过血液流动进行自然温度控制中汲取灵感。这项技术的核心是在人造皮肤内模拟血管的纤维网络。水在特定的温度和流动条件下流经这些纤维,形成一个受控的热释放系统。通过改变这些纤维的扩张程度,主要是通过调节循环频率,可以调节热量的释放。我们的研究结果表明,这种方法可以复制不同人脸和手部区域的不同热特性。因此,机器人脸部在红外图像中看起来更像人类,有助于红外相机对其进行识别。与此同时,假手的温度也更加自然,减少了与人造肢体直接接触时通常会产生的不适感。这项研究的目的是解决假手使用者面临的挑战。这项研究的结果表明,仿人机器人技术的发展方向大有可为,它可以改善触觉互动,重新定义人与机器人的关系。这种创新技术有助于进一步发展,模糊人工辅助工具与自然生物系统之间的界限。

Thermoregulatory integration in hand prostheses and humanoid robots through blood vessel simulation

In this paper, we introduce an innovative approach for generating robotic faces with a thermal signature similar to that of humans and equipping prosthetic or robotic hands with a lifelike temperature distribution. This approach enhances their detection via infrared cameras and promotes more natural interactions between humans and robots. This method integrates a temperature regulation system into artificial skin, drawing inspiration from the human body’s natural temperature control via blood flow. Central to this technique is a fiber network simulating blood vessels within the artificial skin. Water flows through these fibers under specific temperature and flow conditions, forming a controlled heat release system. The heat emission can be adjusted by changing the dilation of these fibers, primarily by modulating the frequency of circulation. Our findings indicate that this approach can replicate the varied thermal characteristics of different human faces and hand areas. Consequently, the robotic faces appear more human-like in infrared images, aiding their identification by infrared cameras. At the same time, the prosthetic hands achieve a more natural temperature, reducing the discomfort typically felt in direct contact with synthetic limbs. The aim of this study was to address the challenges faced by the users of prosthetic hands. The results from this study show a promising direction in humanoid robotics, fostering improved tactile interactions and redefining human–robot relationships. This innovative technique facilitates further advancements, blurring the lines between artificial aids and natural biological systems.
