Note: Most internal competencies (thinking, learning, planning) 
should not really be separated alone here,
as I believe most of the time, spatial concepts
are formed and used in the context of other more conplex entities.
However, there are 
some primitive internal competencies, that 
may need to be acquired and formed at an early state
of life (of a robot).

Ability to think of possible location, 
possible path, etc. Closer distance, closer location.
