Deep Analysis
Innovations
- Goes beyond prescribing a fixed definition of world models, instead examining methods that exhibit core capabilities
- Analyzes world model approaches across perception, prediction, and control in robotic manipulation
- Distills core components, capabilities, and functions that a fully realized world model should possess
Methodology
This survey reviews methods in robotic manipulation that exhibit core capabilities of world models, analyzing their roles in perception, prediction, and control, and identifying key challenges and solutions. It does not limit itself to methods explicitly labeled as world models, but rather examines approaches that demonstrate world model-like behaviors.
Key Results
The survey identifies key challenges and solutions in robotic manipulation world models, and distills the core components, capabilities, and functions that a fully realized world model should possess.
Limitations
- Scope is limited to robotic manipulation, not covering other domains like navigation or decision-making
- Does not provide a fixed definition of world models, leaving ambiguity in scope and architecture
- As a survey, it does not present new experimental results or validate proposed components empirically
