1. A system for maintaining a digital map of a workspace, the system comprising:
- a plurality of mobile drive units configured for material transportation within the workspace;
a plurality of fixed sensors disposed at a plurality of fixed locations within the workspace;
a plurality of mobile sensors connected to a plurality of automated devices, the plurality of automated devices configured for selective deployment within the workspace; and
a management module in communication with the plurality of mobile drive units, the plurality of fixed sensors, and the plurality of automated devices, the management module configured to;
maintain a first version of the digital map of the workspace based at least in part on first visual information received from a portion of the plurality of fixed sensors, the digital map comprising a plurality of regions corresponding to a plurality of areas within the workspace;
identify a difference between a region in the first version of the digital map and a corresponding region in a second version of the digital map, the difference representative of a physical change in a workspace condition in an area of the workspace corresponding to the region and the corresponding region;
cause an automated device of the plurality of automated devices to (i) navigate to the area in the workspace, (ii) orient a mobile sensor of the plurality of mobile sensors, and (iii) use the mobile sensor to collect additional visual information at the area;
receive the additional visual information from the mobile sensor; and
update the digital map based at least in part on the additional visual information.

Abstract
Systems and methods for maintaining a current map of a workspace using on-demand sensors and fixed sensors are described herein. For example, a system may include a fixed sensor positioned within the workspace, an on-demand sensor available for selective deployment in the workspace, and a computing device. The computing device may maintain a digital map of the workspace, identify a region in the workspace for collection of additional sensor information, and cause the on-demand sensor to gather the additional sensor information for updating the digital map.

6. A system for maintaining a global visual representation of a workspace, comprising:
-
a set of fixed sensors positioned within the workspace; an on-demand sensor available for selective deployment within the workspace; and a management module in communication with the set of fixed sensors and the on-demand sensor, the management module configured to; maintain the global visual representation of the workspace based at least in part on first sensor information from at least one fixed sensor of the set of fixed sensors; identify, based at least in part on the global visual representation, an area of the workspace for collection of additional sensor information, the area comprising a physical change in a workspace condition; and in response to identifying the area, cause the on-demand sensor to collect the additional sensor information within the area. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A computer-implemented method for maintaining a digital representation of a workspace, comprising:
-
receiving first sensor information from a first sensor, the first sensor information comprising a representation of workspace conditions present at a particular location within the workspace; identifying a physical obstruction at the particular location based at least in part on the first sensor information; and in response to identifying the physical obstruction, causing an on-demand sensor to gather second sensor information at the particular location, the second sensor information comprising an enhanced representation of the workspace conditions present at the particular location. - View Dependent Claims (17, 18, 19, 20)
