Even if Harel's schema represents a real contribution to filing the gap between user requirements and final implementations, there is few work on its feasibility and none within UML2.This paper addresses this lack. First we use UML2 sequence diagram as a formalism for requirement specification. Then an approach that synthesizes state machines from UML2 sequence diagrams is presented. From the obtained state machines, we implement a transformation to code. The AIBO platform (one of several typesof robotic pets designed and manufactured by Sony) is used as a case study toillustrate our implementation
