World Model Laboratory
An interactive, deterministic laboratory for world models: observe a partially observable scene, form a belief from what you have seen, forecast what comes next, plan a route and act — then replay the same moment with a different action. Interface available in English and Turkish. Runs entirely in your browser.
Scope: the reference trajectory comes from a physics simulation inside an educational universe. It is not a physical measurement and not a validated model of a real robot. The three predictors are hand-coded educational models, not trained foundation models. Errors are calculated between simulated values; these results do not validate real-world transfer, and counterfactual branches are counterfactual simulation under stated assumptions, not causal identification.
What it covers
- Observation and belief: field of view, occlusion and dead-reckoned memory, with a declared information boundary.
- Prediction: constant velocity, simple dynamics and an intentionally biased dynamics predictor, compared on a frozen common belief.
- Planning and acting: finite search over declared action commands, with an assisted pusher proxy.
- Four scenarios: plan a path, predict motion, see the unseen, meet a surprise; plus World Model 101 and a JSON evidence export.
