The focus of this paper is on strategies for adapting a couple of 
internal representations to the actual environment of a mobile robot. 
From the range of approaches, two different (and in a sense 
orthogonal) basic ideas are discussed, regarding computational effort, 
stability, reliability, sensor requirements, and consistency as well 
as their useful applications. The first approach is an exact, 
geometric technique using line representations extracted from the 
information produced by a laser-range finder. The second discussed 
possibility is a qualitative, topologic mapping of the environment 
using neural clustering techniques. Both presented classes of 
environment-modelling strategies are evaluated on the basis of 
principal arguments and of simulations resp. tests on real robots. 
Experiences from the MOBOT resp. the ALICE project are discussed 
together with some related work.
