超越 VLA：World Action Models 如何重塑机器人操作
Beyond VLAs: How World Action Models Reshape Robot Manipulation
NVIDIA 提出 World Action Models，用于解决机器人策略泛化难题：传统策略在训练场景有效，物体形状、位置或光照变化后往往失效。该模型通过让策略理解任务背后的物理规律而非模仿演示，从而泛化到新条件，这一能力来自其骨干网络。

A central challenge in robotics is building policies that generalize beyond the demonstrations they’re trained on. A policy that succeeds in a training scene often fails when object shapes, positions, or lighting change. Generalizing to these new conditions requires the policy to understand the tasks underlying physics, not just mimic the demonstrations. This ability comes from the backbone it’s…
