Humanoid-COA paper evaluates zero-shot loco-manipulation on Unitree H1-2

Evidence notes
- Humanoid-COA combines multimodal foundation models with embodied chain-of-action reasoning for zero-shot humanoid loco-manipulation.
- Experiments use Unitree H1-2 and G1 humanoids in open-area and apartment environments.
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.
