Key points
- It proposes a privileged-supervision approach in which a 3D tracker is used only during training and removed at deployment.
- Track queries match the 3D tracker features extracted from Track4World and inject them into the VLA action head.
- It reaches 82.3 percent zero-shot on LIBERO-Plus, improving by 7.6 percentage points over the unaligned version and by 3.0 points over LaMP.
- It records 80.44 percent on RoboTwin 2.0 clean and 81.48 percent on randomized.
- On four real dual-arm robot tasks, it reaches 67.5 percent, which is 25.0 percentage points higher than the unaligned version.
