Recognition System of Tableware and Robot Navigation using Invisible Mark

Abstract

It is preferable that marks are invisible for human. In this research, an invisible mark made of photochromic material is developed. This mark is added to the edge of the tableware. Using two colors, a barcode mark is achieved. Other information effective for handling task of the tableware could be added to the barcode mark. An invisible barcode landmark is also developed for localization of a mobile home robot.
