Intelligent agents (both biological and artificial/mechanical) are given tasks to perform in various different environments. Knowledge learned in one environment is then available for use in others. With any given A.s.a. H. agent some of these may be real world environments being experienced by its robots while others may be simulations* experienced by simulated robots. The artificial world of the simulation can, in turn, have been learned** by some other*** A.s.a. H. agent(s) and its robots as it acts in the real world.
* like those provided by the RobotBASIC simulator for example
** like a map, perhaps (also, see my blogs of 7 Jan. 2015 and 7 May 2017)
***or possibly the same agent
