“…Simultaneous Localization and Mapping (SLAM) is a fundamental problem in mobile robotics and has been studied extensively in the robotics literature (Thrun et al, 1998(Thrun et al, , 2000Castellanos et al, 2001;Nebot, 2001, 2002;Tardos et al, 2004;Newman et al, 2002;Montemerlo et al, 2002;Nieto et al, 2002;Liu and Thrun, 2002;Fenwick et al, 2002;. For the most part, research has concentrated on SLAM in static environments.…”
