Abstract. An approach to the problem of interoperability in open and heterogeneous multirobot system is presented. It is based on the paradigm of Service Oriented Architecture (SOA) and a generic representation of the environment. A robot, and generally a cognitive and intelligent device, is seen as a collection of its capabilities exposed as services. Several experimental protocols (for publishing, discovering, arranging, and executing the composite services) are proposed in order to assure the interoperability in the system. The environment representation, the description language for tasks and service interfaces definition, as well as the protocols constitute together the proposed information technology for automatic task accomplishment in an open heterogeneous multirobot system.

A business service has well founded structure where its operations (corresponding to request-quote, order-contract, invoice-payment) are related to each other. These relations cannot be expressed in WSDL. The request-quote operation corresponds to SLA negotiations and can be performed in a universal description language such as OWL that can also express all the relations between service operations mentioned above. Generally, from the e-business perspective the following notions are important: (1) Service architecture. (2) Communication protocols in e-business processes. These notions are crucial for providing standards necessary for creating open, heterogeneous and scalable systems for realizing complex e-business processes. These notions are discussed in the paper.
