Open-source handheld gripper (~€490 BOM) + browser-based SLAM processing pipeline converts human demonstrations into LeRobot datasets without needing a robot.
Summary
Removes hardware gatekeeping from robot learning data collection—developers can now record training data from any environment and contribute to shared datasets, addressing the actual bottleneck in visuomotor policy training.

Implementation verdict
Replaces expensive teleoperation rigs and lab-bound data collection. Requires building Grabette from off-shelf components (Raspberry Pi, OAK-D camera, magnetic encoders), uploading recordings to Hugging Face, and running SLAM processing via browser. Production-ready for early adopters; community contribution model is the real test.
