HoST paper deploys diverse-posture standing-up control on Unitree G1

Evidence notes
- HoST learns humanoid standing-up control from scratch using multi-critic reinforcement learning and curriculum training.
- The authors report direct deployment of the trained controllers on the Unitree G1 humanoid robot.
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.
