Embodiment Construction

[0040] 1 Introduction

[0041] The present invention is directed to systems and methods for allocating mapping, localization, planning, control and task execution in a multi-robot environment. Specifically, according to one embodiment of the invention, mapping, positioning, planning and control functions are assigned to one mobile platform (navigator), while task execution functions are assigned to at least one second mobile platform (functional robot).

[0042] The present invention overcomes the shortcomings of conventional systems currently in use by providing near real-time manipulation and task completion. One ideal application of the present invention is in home or office cleaning, which typically involves multiple and repetitive tasks such as vacuuming, sweeping, mopping. However, the invention can also be used in any environment where multiple robots are manipulated to perform assigned tasks.

Abstract

An autonomous mobile robot system allocates mapping, localization, planning and control functions to at least one navigator robot and allocates task performance functions to one or more functional robots. The at least one navigator robot maps the work environment, localizes itself and the functional robots within the map, plans the tasks to be performed by the at least one functional robot, and controls and tracks the functional robot during task performance. The navigator robot performs substantially all calculations for mapping, localization, planning and control for both itself and the functional robots. In one implementation, the navigator robot remains stationary while controlling and moving the functional robot in order to simplify localization calculations. In one embodiment, the navigator robot is equipped with sensors and sensor processing hardware required for these tasks, while the functional robot is not equipped with sensors or hardware employed for these purposes.

Description

field of invention [0001] The present invention relates generally to mobile robotic systems, and more specifically to systems and methods for allocating mapping, localization, planning, control, and task performance functions in an autonomous multi-platform robotic environment. Background technique [0002] Mobile robots have been researched, developed and used to handle various tasks such as cleaning and security. Most mobile robots are non-autonomous: that is, they cannot navigate autonomously. The economic benefits offered by non-autonomous robots are limited by the robot's inflexibility and substantial installation expense. A skilled technician must be hired and paid for pre-programming that causes the robot to follow a specified route and perform specified tasks. It may be necessary to install objects in the environment to guide the robot, such as tracks, underground signal transmission lines, signs or sensors. It may also be necessary to make further changes to the ...
