PartNet / PartNet Mobility

PartNet and PartNet Mobility are discussed in E244｜端到端vs上下分层：机器人路径之争，正在转向？ as 3D data-set steps beyond ShapeNet. The source says they add object parts and mobility constraints, making them more relevant to robot manipulation than shape-only data.

The episode still treats them as far from enough: a few thousand articulated objects cannot cover open-world bottle caps, drawers, deformable materials, friction, elasticity, and other physical details. This limitation becomes one reason 速度科技 / Sudu Technology emphasizes Structured 3D Robot Data and Sim2Real rather than relying only on internet video or existing 3D assets.

Connections

• Su Hao / 苏浩 and ShapeNet - data lineage in the source.
• Structured 3D Robot Data - broader concept this source adds.
• Open-World Robot Manipulation - capability target that demands more than part labels.
