金吾财讯 | 机器人概念股涨幅居前，截至发稿，优必选(09880)涨4.17%，金力永磁(06680)涨3.40%，德昌电机控股(00179)涨2.43%，越疆(02432)涨1.85%，速腾聚创(02498)涨1.39%。消息面上，国泰海通发研报指，目前人形机器人旋转关节方案以谐波减速器和行星减速器为主。核心原因在于谐波减速器和行星减速器在体积重量、精度、成本和扭矩输出特性上更贴合需求：谐波减速器结构简单紧凑、传动精度高且低背隙，行星减速器多级齿轮传动，扭矩强劲，动力表现优异。二者均能在受限空间内满足机器人对精准动作、扭矩输出的要求，且成本通过技术发展和规模效应逐步优化；摆线针轮减速器承载能力较高，传动精度较高，体积小、重量轻，多齿啮合带来传动平稳的优良特性，但零件导致工艺较复杂，且精度相比谐波稍低、传动效率比行星稍低，在过去未充分适配人形机器人场景。摩根士丹利表示，人形机器人今年下半年将在中国“被广泛采用”。摩根士丹利还预测称，未来中国在人形机器人领域将愈发占据优势，与美国等其他国家的差距将逐步拉开。
