The ARLTAB panels -- one for each of ARL's six directorates -- reviewed many individual projects, but the panels came away with no sense of a collective vision across directorates guiding these efforts and encountered relatively few cross-organizational projects jointly managed and jointly monitored by several directorates. Yet this field of robotics and autonomous systems cries out for collaborative efforts that range from design, to materials development and/or selection, to com munication, to sensing, to human-machine interfacing.

At VTD, some high-quality technical work contributes significantly to the work of the overall technical community. For example, the compressortip-injection stall control work that couples experimental data and computational fluid mechanics is state of the art and will enable the industrial design community to improve gas turbine fuel economy and reduce compressor stall.

. WMRD's initiative in affordable precision munitions applies an appropriate technical approach that features a combination of analytical and computer modeling, laboratory/bench experiments, and full-scale field testing, including guide-to-hit tests.

ARL's recently initiated program Materials in Extreme Dynamic Environments (MEDE) is a very promising approach to creating a collaborative team to address multiscale modeling to contribute to the achievement of significant Army materials applications.

At WMRD, the Gun Liner Emplacement by Elastomeric Materials (GLEEM) Processing project seems to involve very applied engineering with little evidence of systematic R&D or modeling to guide the effort.

A central concern is the limited contact of ARL researchers with the broader robotics community: ARL research projects generally seem to involve too little contact and collaboration with existing robot manufacturers, academics conducting robotic research, and other Army users of robots. This leads to the possibility of work that is duplicative or behind the state of the art.

ARL is addressing this challenge through two newly initiated programs in the evolving area of multiscale modeling and associated experimentation: the MEDE Program and the Multiscale Multidisciplinary Modeling of Electronic Materials Program. Each of these programs will involve cooperative research alliances that foster collaborative efforts among external institutions and with ARL researchers.

One significant relevant approach underway at ARL is the Multiscale Mul tidisciplinary Modeling of Electronic Materials Program mentioned above. Materials by Design In past eras, materials have been principally selected almost exclusively on the basis of hands-on experience with a material's characteristics -- that is, the material was found or manufactured and then, based on its performance compared to that of other materials, was selected as the preferred material for a given application.

Over the past five decades, this initial coupling of processing know-how and experience with rules of thumb has given way, first, to an increasing level of scientific and engineering insight into the domi nant mechanisms that control microstructure development linked to process modeling and, thereafter, to the predictive modeling of the correlations between microstructure, properties, and performance. This evolution in the process flow paradigm governing materials development to a rapidly accelerated level of using materials modeling to link processing to structure to properties to performance has seen great strides in recent years.

In general, ARO demonstrated increasing attention to such collaboration, and the Board looks forward to continuing improvements in ARO's cognizance and support of the missions of the directorates.
