This paper, we have proposed an appropriate place specification method for tidy-up robotic service based on a time series analysis algorithm. The system is able to suggest an appropriate place which analyzed from an object trajectory information. For example, when we have finished using a cup, the system should suggest a sink for washing and then a shelf for storing. Furthermore, we proposed and built the object information management system to manage the related information. The system also provided a hardware called Robotic Technology Case (RT-Case) to collect object log and trajectory information.
