This work aims to identify the effects that a series of environmental factors, specific to the industrial conditions, have on the materials in the structure of soft robots and, therefore, on soft robotics systems. The purpose is to understand the changes in the mechanical characteristics of silicone materials, with the aim of transferring soft robotics applications from the sphere of services in the industrial field. Distilled water, hydraulic oil, cooling oil, and UV rays are the environmental factors considered in which the specimens were immersed/exposed for 24 h according to ISO-62/2008. The analysis was carried out on two of the most widely used materials in the field, belonging to the category of silicone rubber, which were subjected to uniaxial tensile tests on the strength testing machine Titan 2 Universal. The results show that the greatest impact on the characteristics of the two materials was when exposed to UV rays, while the other media tested had relatively little impact on the mechanical and elastic properties (tensile strength, elongation at break, and tensile modulus) of these materials.
这项工作旨在确定一系列特定于工业条件的环境因素对软机器人结构中的材料以及由此对软机器人系统产生的影响。目的是了解硅酮材料机械特性的变化，以便将软机器人应用从工业领域的服务范畴进行转移。蒸馏水、液压油、冷却油和紫外线是所考虑的环境因素，根据ISO - 62/2008标准，将试样在其中浸泡/暴露24小时。分析是针对该领域中使用最广泛的两种材料进行的，它们属于硅橡胶类别，在Titan 2通用强度试验机上进行了单轴拉伸试验。结果表明，对这两种材料特性影响最大的是暴露于紫外线时，而其他测试介质对这些材料的机械和弹性性能（拉伸强度、断裂伸长率和拉伸模量）影响相对较小。
