-==Internal state== +  * Internal state: Directly observable state of the robot. Also it's internal representation of the world - it's internal model. 
-Directly observable state of the robot. Also it's internal representation of the world - it's internal model. +  * 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. 
-==External state== +  * Partially observable state: Through a sensor, along with noise eg: camera image pixels 
-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]].
