ECHO paper runs language-to-motion whole-body control on Unitree G1

Evidence notes
- ECHO splits language-driven whole-body control between cloud text-to-motion generation and an edge reinforcement-learning tracker.
- The paper evaluates the system on a retargeted HumanML3D benchmark and physical Unitree G1 hardware.
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.
