If s~s′, then:
(i) they induce the same observation law, and
(ii) for every admissible action, they assign the same transition probability to every equivalence class.
The quotient preserves observable dynamics.

Overall, we propose an operationalisation of "habitat" as a structure-preserving abstraction of an environment, relative to a class of embodied agents.
Here, morphology, sensing, dynamics and actions determine which environmental differenc…
These three are only candidate coarse-grainings. Turning them into quotient POMDPs would require full observation and transition maps, with each proposed partition preserved under every admissible action.

We then sketch three candidate habitats in the same light field:

This is because the orbit map, q₂b((x,y), θ) = (r, θ_rel), induces a bisimulation quotient.
The habitat removes absolute position around the source and retains distance and signed relative heading: how far away the source is, and how much …
Now, place the vehicle in two configurations related by rotation around an isotropic light source, with distance and relative heading fixed.
The sensors give the same readings. Under any fixed wheel-speed action, the successors remain rela…
To show this in action, we consider a class of Braitenberg vehicles.
Vehicle 2b has two light sensors and two wheels, wired contralaterally. Light on the left accelerates the right wheel, turning the vehicle toward the source; equal readin…
The quotient S/~ forms the habitat’s state space. Its observations and transitions are inherited from the environment.
This construction is relative to a chosen agent-environment boundary. Different interfaces or bisimulation relations can…

This coarse-graining identifies environmental states that are indistinguishable from the perspective of an agent type. We define it using a standard bisimulation equivalence.
