Journal ArticleDOI
Using occupancy grids for mobile robot perception and navigation
TL;DR: An approach to robot perception and world modeling that uses a probabilistic tesselated representation of spatial information called the occupancy grid, a multidimensional random field that maintains stochastic estimates of the occupancy state of the cells in a spatial lattice is reviewed.
Proceedings ArticleDOI
High resolution maps from wide angle sonar
Hans P. Moravec,Alberto Elfes +1 more
TL;DR: The use of multiple wide-angle sonar range measurements to map the surroundings of an autonomous mobile robot deals effectively with clutter, and can be used for motion planning and for extended landmark recognition.
Journal ArticleDOI
Sonar-based real-world mapping and navigation
TL;DR: In this article, a sonar-based mapping and navigation system for an autonomous mobile robot operating in unknown and unstructured environments is described, where range measurements from multiple points of view are integrated into a sensor level sonar map, using a robust method that combines the sensor information in such a way as to cope with uncertainties and errors in the data.

Sonar-based real-world mapping and navigation
TL;DR: A sonar-based mapping and navigation system developed for an autonomous mobile robot operating in unknown and unstructured environments is described, which uses sonar range data to build a multileveled description of the robot's surroundings.
