ULTRA paper demonstrates autonomous whole-body loco-manipulation on Unitree G1

Evidence notes
- The ULTRA paper introduces a unified multimodal controller for autonomous humanoid whole-body loco-manipulation.
- The authors evaluate the framework in simulation and on a real Unitree G1 humanoid.
- The work gives G1 a concrete whole-body loco-manipulation benchmark spanning simulation and real-hardware evaluation.
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.
