Layered-control architecture paper demonstrates robust stairs and ledges on Unitree G1

Evidence notes
- The paper argues that a layered control architecture can outperform monolithic end-to-end policies for perception-conditioned humanoid locomotion.
- On Unitree G1 hardware, the approach succeeds across stair and ledge tasks where one-stage perceptual policies fail.
- The release is a direct external benchmark for G1 in unstructured locomotion tasks.
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.
