仿生机械手，掌内传动的局部透视

A single original humanoid robotic hand held in a relaxed open pose, five fingers with segmented metal joints, partial translucent palm cover revealing simplified tendon cables and actuators. Fine white technical outlines overlay only the revealed structure, navy studio background, realistic brushed titanium and polymer pads, no labels, concept visualization not anatomical or manufacturing instructions. Original generic design, no real brand or fabricated specifications.

一只原创人形机器人机械手自然张开，五指带分段金属关节，掌部局部透明外壳露出简化腱索和执行器。细白技术轮廓线只覆盖透视结构，海军蓝棚景、拉丝钛色与聚合物指垫，无标签，概念展示而非制造说明。 原创通用设计，不虚构真实品牌参数。
