1. A method of substantially simultaneously planning a path and mapping an environment by a robot, comprising:
- determining a mean of an occupancy level for a location in a map;
determining a probability distribution function (PDF) of the occupancy level;
calculating a cost function based on the mean occupancy level and a variance of the occupancy level obtained from the PDF; and
simultaneously planning the path and mapping the environment based on the cost function.

Abstract
A method substantially simultaneously plans a path and maps an environment by a robot. The method determines a mean of an occupancy level for a location in a map. The method also includes determining a probability distribution function (PDF) of the occupancy level. The method further includes calculating a cost function based on the PDF. Finally, the method includes simultaneously planning the path and mapping the environment based on the cost function.
