Associations support description of ations shared between participating robots by a language abstraction. In general, associations focus on conceptual modeling of collaboration and may be concretized and implemented in different ways. In rendezvous-based associations the communication and coordination between robots is described by a rendezvous mechanism. The rendezvous-based ion offers understandability through abstract collaboration description contrary to logically distributed robot centric descriptions. KEYWORDS ive Modeling and Programming, Language Abstraction, Rendezvous, Robot Collaboration.
