Practice of Multi-robot Teahouse Based on PRINTEPS and Evaluation of Service Quality

In order to develop services utilizing robots, various AI element technologies and multiple robots and sensors must be integrated. However, at present, it takes a lot of cost to develop such integrated intelligent applications. Currently, we have been developing PRactical INTEligent aPplicationS (PRINTEPS), which is a user-centric platform to develop integrated intelligent applications only by combining five types of modules such as knowledge-based reasoning, speech dialogue, image sensing, motion management, and machine learning. In this paper, we report on a multi-robot teahouse at a university campus festival as a practical application of PRINTEPS. We also report the evaluation of the robot teahouse from the viewpoint of the service quality based on the questionnaires of the customers who experienced the robot teahouse.
