Abstract
Recently, the practical use of a home robot that can accomplish various tasks in a house is expected. Most of the home robots that have been put to practical use so far perform just a simple task, or are used just as communication tools. We are developing a multifunctional home robot based on the 3M concept (Multitask, Modularization, Minimalization), targeting mainly single company employee type households. A GUI is required to facilitate input of a priori information, e. g. furniture location and desired paths by the user. We propose a GUI which is interactive, intuitive and easy to operate.
