The path from simulated robot to real-world deployment has long been paved with domain randomization and crossed fingers. VIRAL, a new paper from NVIDIA and collaborators, achieves **54 consecutive loco-manipulation cycles** on a Unitree G1 humanoid—walking between tables, picking up objects, placing them on trays, and repeating—with zero real-world fine-tuning. What makes this work notable isn't a novel algorithm but rather a carefully documented set of training innovations that reveal why s...
