### AI overview

The article explains how World Action Models (WAMs) use video world models as backbones for robot policies, addressing the physical-generalization limitations of vision-language-action models. It discusses post-training WAMs into specialized policies and presents NVIDIA Cosmos 3 as a foundation for building them.

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...

### AI overview

Grabette is an open, low-cost handheld system for recording robot-manipulation demonstrations without requiring a robot, laboratory, or teleoperation rig. It uses a human-operated gripper and cameras to capture demonstrations and produce robot-ready datasets, with browser-based processing and integration with LeRobot and the Hugging Face Hub.
