Most robot craft construction courses held by regional administrative organs are temporary events, so that it is very difficult to communicate between participants only in the event day. The purpose of our project is to construct the partnership among our small collaborations, such as small collaboration between NPO NPO-RIC and Kanagawa Univ, between Kanagawa Univ. and the after school daycare facility "Okaeri", and between Kanagawa Univ. and Trans Cosmos Ltd., and so on. In this paper, not only the robot craft construction course but also the process of collaboration among our organization with each different output are reported.

Programmable Controllers (PCs) are widely applied in the control of manufacturing systems. The purpose of this paper is to give some basic concepts for the verification methods of sequential control systems. Especially, we propose the modeling method of Ladder Diagram (LD) with the cyclic scan of PC by Petri Nets (PNs). First, some experiments are conducted to examine the relationship between the cyclic scan and the behavior of LD. Second, PNs are used for the qualitative modeling of the behavior of LD, based on IEC61131-3. In addition to LD Boolean logic expressions, we consider the PC operation, described by the cyclic scan, peripherals, memories, scanning ladder rungs. As a result, the difference between the LD description and the behavior, caused by the cyclic scan, can be represented by the proposed PNs. Moreover, the behavior of the PNs can be analyzed by the firing sequences, and then confirmed in good qualitative agreement with that of the experimental results.
