Abstract : Robotic systems are typical examples of hybrid systems where continuous time aspects, related to control laws, must be carefully merged with discrete-time aspects related to control switches and exception handling. These two aspects interact in real-time to ensure an efficient nominal behavior of the system together with safe and graceful degradation otherwise. In a mixed synchronous/asynchronous approach, ranging from user's requirements to run-time code, ORCADD provides formalized control structures, the coordination of which is specified using the ESTEREL synchronous language and formally verified using the FC2TOOLS package. CAD tools have been designed and integrated to help the users along the steps of programming, verification and implementation processes
