WebDec 28, 2015 · The main novelty of fastSLAM 2.0 consists in the update of the robot's pose which does not only keep into account of the odometry but also of the most recent measurement. FastSLAM 2.0 separates the estimation of the state of the vehicle from the state of the map, which in this case, is the set of landmarks one is using to self-localize. … http://ais.informatik.uni-freiburg.de/teaching/ws13/mapping/pdf/slam13-gridfastslam.pdf

WebUnlike other grid-based SLAM algorithms, which use occupancy grid maps, our algorithm uses a new mapping technique that maintains a posterior distribution over the height variance in each cell. This idea was motivated by our experience with outdoor navigation tasks, which has shown height variance to be a useful measure of traversability.

WebGrid based FastSlam relies on the same principle that Landmakr based FastSlam. The difference is that we are not working with each grid cell as a landmark, but the whole gridmap itself. For Grid based FastSlam, each particle updates its own grid-map using the data from the range sensor (Lidar, UltraSound, etc.) and its odometry.
