+  * External state: What's happening in the real world. Can only be known via a robot's sensors.
+  * Observable state: known at all times, usually internal - eg. battery state.

-What's happening in the real world. Can only be known via a robot's sensors.
+  * Hidden state: What you are actually interested in, in the real world - eg: position of user's head. Can't be directly known, must be indirectly inferred from (maybe multiple) sensors. See [[sensor fusion]].
