Multi-function robotic device

Abstract

A multi-function robotic device may have utility in various applications. In accordance with one aspect, a multi-function robotic device may be selectively configurable to perform a desired function in accordance with the capabilities of a selectively removable functional cartridge operably coupled with a robot body. Localization and mapping techniques may employ partial maps associated with portions of an operating environment, data compression, or both.

1 . A multi-function robot comprising:
 a drive mechanism;   an electronics module to provide instructions to said drive mechanism to position said robot in an operating environment; and   a sensing apparatus including an optical assembly to provide locality data to said electronics module, the locality data related to a location of said robot in the operating environment, thereby enabling said robot to determine its location in the operating environment independent of calibration with reference to an external source;   wherein said robot is configured to perform a mopping, sweeping, or vacuuming function in use.   
   
   
       2 . The multi-function robot of  claim 1  further comprising a sensor array to provide proximity data to said electronics module, the proximity data related to a position of said robot relative to an obstacle in the operating environment, thereby enabling said robot to avoid obstacles in the operating environment independent of the locality data.
