2000+真实场景搬进仿真！一个导航模型零样本“通吃”四种机器人本体

TL;DR - Light Robotics unveiled three technologies aimed at scaling Physical AI from training through real-world deployment. Its LightNav-0 model uses simulated versions of 2,000+ real scenes and transfers zero-shot across humanoid, quadruped, wheeled, and aerial robots.

• LightNav-0 generated 4,000+ hours of vision-language-action experience and found that broader environment coverage improved generalization more reliably than adding trajectories within the same environments.
• Its Point CoT spatial-reasoning method improved average task success by 8.4 percentage points and SPL by 5.7 points across eight ablations.
• LightParkour expands short human motion clips into adaptable contact-rich skills through physics simulation and curriculum learning, then distills multiple skills into one policy.
• Light REACT uses interaction history, multi-teacher distillation, and preference reinforcement learning to adapt locomotion after disturbances or hardware damage without explicit fault labels.
