We propose a new human-friendly/cooperative working support robot named PaDY (in-time Parts/tools Delivery to You robot). This system achieves reduction of the worker's load and improvement of the work efficiency by recognizing the worker's behavior in the production site, and supporting the worker. PaDY recognizes worker's movement in the production site, and estimates the worker's intention. And, PaDY delivers parts and tools that the worker needs to worker's hand when it is necessary. In this paper, the way to classify the worker behavior by using LRF in the production site is described.
