Map Merging Strategies for Multi-robot FastSLAM: A Comparative Survey

A comparative survey between the two basic strategies used to combine partial landmark based maps in multi-robot systems, data association and inter-robot observations (Rendezvous), is presented. The simulated environment is a flat place populated by trees, which are going to be mapped by a two-mobile robot team equipped with laser range finders in order to measure every tree (landmark) location and width. Partial maps are estimated using the algorithm FastSLAM2.0.
