植物利用许多策略来有效地在土壤中移动，例如从顶端生长，向热带运动和形态变化。在本文中，我们提出了一种方法，将玉米根的形态特征转化为一种新的软机器人设计，将能够在土壤中移动。该方法利用图像处理和曲线拟合技术提取Z.玉米的主根我们在3D模型（CAD）中实现了根轮廓的解析转换，以通过3D打印技术制造根状探针。然后，我们对人工根状探针与不同尖端形状（圆柱形、圆锥形、椭圆形和抛物线形）和直径（11、9、7、5和3 mm）的探针进行了比较分析。结果表明，相对于其他形状的开发的探针的所有直径的生物启发探针的能量消耗和穿透力更好。对于100 mm的穿透深度和7 mm的探针直径，生物激发探针的能量消耗相对于圆柱形探针小89%，相对于圆锥形探针小26%。所考虑的尖端形状的侵彻性能进行了评估，也通过数值模拟，获得了良好的协议与实验结果。对植物根系形态、运动策略和材料特性的进一步研究可以开发出可在具有挑战性的环境中利用的创新生物启发解决方案。这项研究可以在不同的领域带来突破性的方案，如勘探任务，环境监测，岩土工程研究和医疗应用。
Plants use many strategies to move efficiently in soil, such as growth from the tip, tropic movements, and morphological changes. In this paper, we propose a method to translate morphological features of Zea mays roots into a new design of soft robots that will be able to move in soil. The method relies on image processing and curve fitting techniques to extract the profile of Z. mays primary root. We implemented an analytic translation of the root profile in a 3D model (CAD) to fabricate root-like probes by means of 3D printing technology. Then, we carried out a comparative analysis among the artificial root-like probe and probes with different tip shapes (cylindrical, conical, elliptical, and parabolic) and diameters (11, 9, 7, 5, and 3 mm). The results showed that the energy consumption and the penetration force of the bioinspired probe are better with respect to the other shapes for all the diameters of the developed probes. For 100 mm of penetration depth and 7 mm of probe diameter, the energy consumption of the bioinspired probe is 89% lesser with respect to the cylindrical probe and 26% lesser with respect to the conical probe. The penetration performance of the considered tip shapes was evaluated also by means of numerical simulations, obtaining a good agreement with the experimental results. Additional investigations on plant root morphology, movement strategies, and material properties can allow the development of innovative bioinspired solutions exploitable in challenging environments. This research can bring to breakthrough scenarios in different fields, such as exploration tasks, environmental monitoring, geotechnical studies, and medical applications.
