2. WP 2 Architectures 2 Annual Assessment, March 27, 2008, Prague Objectives in WP 2 Preparing a set of standard defining activities on the following topics of advanced robotics, including: Specification of a reference architecture for mobile manipulation and service robots Resulting either in: –an action plan for a standard defining activity or –an action plan and a recommendation/proposal to the European Commission for a supported activity (e.g. a open-source project with financial support in FP7) or –an action plan for a community driven open-source activity with seed-money for a project office or alike Year 1 results point at option B or C as reasonable.

3. WP 2 Architectures 3 Annual Assessment, March 27, 2008, Prague Difficulties State of the art report format/presentation Personnel resources 1 less than planned (D2.1 delay) WP2&3 connection appears overlapping DoW meeting schedule not practical Making points of agreement tangible Motivation for industrial assessments Open standards depend on closed data “I’ll certainly not use your architecture”

4. WP 2 Architectures 4 Annual Assessment, March 27, 2008, Prague Progress Efforts & deliverables [difficulties, previous slide]: Successful expert meetings and workshops. Contributions to wiki and community dialogue. Detailed studies on specific topics (BROS, Task). Tightly integrated with WP3 (community overlap) Tech results [very promising]: Community consensus 1: Something need to be done, and the time is about right: …. Consensus 2: We will never have one common reference architecture. Agreements about what we disagree about: real- time requirements, run-time platforms, … Is the RoSta architecture aim ‘mission impossible’??

5. WP 2 Architectures 5 Annual Assessment, March 27, 2008, Prague Mission impossible?? The topic of robot reference architectures has been worked on for the last two decades, without successful standards emerging (see list in DoW). 15 years ago (workshop Nice 1992) the conclusion was that we need to build more systems The world wide web appeared at that time. Today, Internet applications have good implications on software principles and hardware cost State-of-the-art today could fill 1000+ pages, or one page stating a list of useful ideas, or.. Open standards and open source, what role? What/any enablers for a RoSta breakthrough?

WP 2 Architectures 6 Annual Assessment, March 27, 2008, Prague Enabling technologies Internet, triggering: Networked software Security measures Safe languages Semantic web Key developments in: Embedded systems and mechatronics (HW&SW) Software business models and open source Examples of key developments: XML – RDF – OWL – SPARQL (Jan 2008) [For merging human-robot interaction modalities in SMErobot] Ethernet – IP – XDF – XSL – WSDL – DSSP [Assessed for Plug-and-Produce in SMErobot; Microsoft related]

7. WP 2 Architectures 7 Annual Assessment, March 27, 2008, Prague Situation Problems: Reuse not even the case within a lab Few shared platforms, hampering scientific values Industrial development re-implementing controls Public funding goes to re-implementation Technologies missing for efficient reuse Approach: Multiple reuse perspectives (not layers) Middleware and frameworks in thin layers Bottom-up definitions and implementations Separation of mechanism and policy

9. WP 2 Architectures 9 Metadata & ontology-based integration Microsoft for robotics: CCR Runtime DSSP networking based on SOAP/XML Schemas and defs partly hidden; Microsoft lock-in  Microsoft for Media: Metadata integration Media → device/service www.microsoft.com/imm states: IMM Introduces Powerful Metadata Framework Interactive Media Manager introduces a powerful, XML-based metadata model that uses the Resource Description Framework (RDF) and Web Ontology Language (OWL) specifications from the World Wide Web Consortium. This RDF model allows companies to add nuance and intelligence to media management beyond what is possible with traditional metadata. Computers can automatically understand complex relationships between media assets and categories. Potential benefits of this approach include: improved search relevance, enhanced workflow tracking, and automatic transfer of metadata properties to new assets during transcoding. Most importantly, the IMM RDF model overcomes traditional barriers to metadata sharing between external systems. Annual Assessment, March 27, 2008, Prague

10. WP 2 Architectures 10 Annual Assessment, March 27, 2008, Prague Perspectives for reuse of robot software Targeted studies (with Herman B) : Design of Robotics Software Standards; a bottom-up approach to standardization. Task specification principles, with Tomas Olsson (now at ABB Robotics). Four levels of perspectives for interfacing and sharing of system components/ knowledge. Each level refers back to the next higher one. Multiple versions permitted except for the ontology that defines the agreed definitions of the domain.

11. WP 2 Architectures 11 Perspectives and links on the wiki  Section Standardization and Reuse  Reflecting the four perspectives.  For each perspective: data and algorithms.  Applies to the 3 parts: Task Environm.Robot Annual Assessment, March 27, 2008, Prague
