Abstract
Because system development is becoming complex year by year, Model-based design is getting recognized to be important. In Model-based approach, by using model to describe the system, development efficiency can be improved and errors can be reduced. To make model, we adopted SysML which was standardized by OMG (Object Management Group) in 2006 to manage engineering systems by extending UML (Unified Modeling Language). In this research, we made model of the robot system by focusing the behavior the autonomous mobile robot which participated in Real World Robot Challenge 2009 (Tsukuba Challenge). By applying SysML to actual robot system, we verified the availability of SysML.
