在对制作机器人的材料选择问题上，
大型机器人模型制作厂家认为设计人员通常主要考虑3个方面:使用要求、工艺要求和经济要求。根据材料的使用要求，选择材料的一般原则有:
In terms of material selection for robot manufacturing, large robot model manufacturers believe that designers usually consider three aspects: use requirements, process requirements and economic requirements. According to the use requirements of materials, the general principles for selecting materials are:
(1)零件尺寸取决于强度，且尺寸和重量又受
(1) The size of the part depends on the strength, and the size and weight are affected by
到某些限制时，应选用强度较高的材料。在静应力下工作，应力分布均匀，如拉伸、压缩和剪切的情况下，宜选用组织均匀，屈服极限较高的材料;在变应力下工作的零件，应选用疲劳强度较高的材料。
When reaching certain limits, materials with higher strength shall be selected. When working under static stress, the stress distribution is uniform, such as in the case of tension, compression and shear, the material with uniform structure and high yield limit should be selected; Parts working under variable stress shall be made of materials with high fatigue strength.
(2)滑动摩擦力工作的零件，应选用减摩性能
(2) Friction reducing performance shall be selected for the parts working with sliding friction
好的材料;在高温下工作的零件应选用耐热材料;在腐蚀介质中工作的零件应选择耐腐蚀材料。
Good materials; Parts working under high temperature shall be made of heat-resistant materials; Corrosion resistant materials shall be selected for parts working in corrosive medium.
材料的各种性能指标中.只取其中之一(如强度极限、疲劳极限等)作为选择材料的依据是不合理的，由于减轻质量常是设计机器人的主要要求之一，故可以采用质量指标对零件进行评定，然后选择合适的材料。
It is unreasonable to take only one of the various performance indicators of materials (such as strength limit, fatigue limit, etc.) as the basis for selecting materials. Since reducing mass is often one of the main requirements for designing robots, quality indicators can be used to evaluate parts and then select appropriate materials.
选材方法：选取何种材料构成其结构本体是详细设计中必然要遇到的问题。一个结构件的设计需要从材质、剖面结构、构建组合形式等方面加以考虑，以便妥善应力、变形、质量、固有振动频率等问题。
Material selection method: it is an inevitable problem in detailed design to select which material to form its structure body. The design of a structural member needs to be considered from the aspects of material, section structure, construction and combination form, so as to properly solve the problems of stress, deformation, mass, natural vibration frequency, etc.
