Abstract
A robotic mapping method includes scanning a robot across a surface to be mapped. Locations of a plurality of points on the surface are sensed during the scanning. A first of the sensed point locations is selected. A preceding subset of the sensed point locations is determined. The preceding subset is disposed before the first sensed point location along a path of the scanning. A following subset of the sensed point locations is determined. The following subset is disposed after the first sensed point location along the path of the scanning. The first sensed point location is represented in a map of the surface by an adjusted first sensed point location. The adjusted first sensed point location is closer to each of the preceding and following subsets of the sensed point locations than is the first sensed point location.
