Snappy: Snapshot-based robot interaction for arranging objects

Photograph is a very useful tool for describing configurations of real-world objects to others. People immediately understand various pieces of information such as “what is the target object” and “where is the target position” by looking at a photograph, even without verbal descriptions. Our goal was to leverage these features of photographs to enrich human-robot interactions. We propose to use photographs as a front-end between a human and a home robot system. We named this method “Snappy”. The user takes a photo to remember the target in a real-world situation involving a task and shows it to the system to make it physically execute the task. We developed a prototype system in which the user took a photo of a dish layout on a table and showed it to the system later to then have robots deliver and arrange the dishes in the same way (Figure1 and Figure2).
