robot arm 3d model

This is an industrial robot, not a humanoid character; only base + torso + two arms. Generate a high-fidelity 3D model of the ABB YuMi dual-arm collaborative robot (IRB 14000) as an industrial product-grade asset suitable for scientific visualization. The robot must consist of a compact base plate, a central torso column, and two symmetric articulated arms mounted at the upper torso (left and right). Enforce strict bilateral symmetry and correct kinematic structure (dual-arm manipulator; no humanoid anatomy). Design language: smooth, rounded housings with a lightweight magnesium internal skeleton covered by a protective plastic sheath and soft external padding on the arms; avoid any pinch-point-like gaps in the joint covers. Include distinct joint modules (shoulder, elbow, wrist) with clean part segmentation and continuous CAD-like surfaces. Materials and appearance: matte off-white body shells and torso housing, dark gray joint covers and forearm segments, subtle seams between components; minimal specular hi
