Hierarchical object-representation paper evaluates perception with Unitree B2 dataset

Evidence notes
- The paper studies hierarchical object representation for spatial robot perception using points, meshes, and superquadrics.
- It evaluates perception on a dataset collected with a Unitree B2 robot platform.
Company context
Develops quadruped and humanoid robots, with strength in dynamic locomotion, vertically integrated hardware, and relatively low-cost commercial deployment. Unitree is one of the clearest examples of a legged robotics company moving from research visibility into real productisation and broader market distribution.
