As various home robots come into homes, the need for efficient robot task management tools is arising. Current tools are designed for controlling individual robots independently, so they are not ideally suitable for assigning coordinated action among multiple robots. To address this problem, we developed a management tool for home robots with a graphical editing interface. The user assigns instructions by selecting a tool from a toolbox and sketching on a bird’s-eye view of the environment. Layering supports the management of multiple tasks in the same room. Layered graphical representation gives a quick overview of and access to rich information tied to the physical environment. This paper describes the prototype system and reports on our evaluation of the system.
