Technical details
- Target-guided trajectory selection: Candidate motions are projected onto images for vision-language model evaluation
- Closed-loop architecture: Observes, understands goals, selects skills, acts, and verifies results
- In-context visual guidance: Separates target localization (vision-language model) from motion control (action model)
- MolmoSpaces benchmark: 230,000 indoor environments, 130,000 object assets, four tasks (Pick, Pick and Place, Open and Close)
FAQ
