Lab Meeting May 10th 2007 (Jeff): Multi-Robot Marginal-SLAM

Title: Multi-Robot Marginal-SLAM

Authors: Ruben Martinez-Cantin, Jose A. Castellanos, and Nando de Freitas

Abstract:
This paper has two goals. First, it expands the presentation of the marginal particle filter for SLAM proposed recently in [Martinez-Cantin et al., 2006].In particular, it presents detailed pseudo-code to enable practitioners to implement the algorithm easily. Second, it proposes an extension to the multi-robot setting. In the marginal representation, the robots share a common map and their locations are independent given this map. The robot's relative locations with respect to each other are assumed to be unknown. The multi-robot Marginal-Slam algorithm estimates these transformations of coordinates between the robots to produce a common global map.
