Formulating Redesign Strategies For Product Evolution: a Proactive Approach to Managing Technological Innovation @ University of Maryland College Park
With support from the National Science Foundation's Innovation and Organizational Change Program and GOALI, this research focuses on the development of an intelligent product representation for evolvable designs that can determine when new innovation indicates that a change in a previous decision is warranted. Deciding when to redesign a product is one of the most important decisions made by any company. Incorrect redesign timing can lead to a variety of problems and poor market response. Current strategies for deciding when to redesign products are usually ad hoc in nature, and may result in a significant lag between the time a technological innovation occurs and the time when it is successfully incorporated into a product design.
The researchers are developing decision-making models that will work on intelligent product representations and generate suggestions for redesign These decision making models perform a detailed trade-off analysis whenever technological or business constraints change in the intelligent product representation. These models incorporate decision variables, design constraints, and evaluation criteria that have led to the decisions currently in use. The project will develop a multi-disciplinary course sequence that will incorporate the latest advances in the management of technology area into engineering and business curriculum.

Curriculum Enhancement to Introduce Product Development with Bio-Inspired Concepts Hugh Bruck, Satyandra Gupta, Edward Magrab, and Elisabeth Smela
Mechanical Engineering Department University of Maryland, College Park, Maryland
Bio-inspired products and devices take their inspiration from nature. Current mechanical engineering curricula do not cover design concepts or manufacturing techniques needed to develop such products and devices. We propose to enhance the mechanical engineering undergraduate curriculum by integrating recent advances in the design, analysis, and manufacturing of bio-inspired products and devices through the following objectives: 1. Insert a new sequence of instructional materials on bio-inspired concepts into the mechanical engineering curriculum. 2. Develop a new senior elective entitled Product Development Using Bio-inspired Concepts. 3. Revise two senior electives in micro-electromechanical systems area to include more complete treatments of special manufacturing processes that can be used to realize bio-inspired products. 4. Assess the projects of the undergraduate mechanical engineering students in their capstone design course to evaluate their retention and utilization of the new material. 5. Conduct one workshop to transfer the new materials and establish a feedback mechanism for enhancing the curriculum. 6. Disseminate the materials developed for the new modules and the course notes for the new senior elective through a dedicated web site. 7. Present a summary of our experiences at two conferences.
The result of the proposed curriculum enhancement will be a new generation of mechanical engineers who can develop products and conduct research for a wide variety of applications utilizing bio-inspired concepts. The proposed project will (1) integrate emerging manufacturing technologies and new design analyses based on biological principles into the Mechanical Engineering curriculum, (2) utilize multi-media technology for disseminating course content, and (3) train graduate students and faculty participating in its implementation in an emerging technology and thereby contribute to faculty development.

Collaborative Research: Manufacturing of Mesoscopic 3d Articulated Devices Using Robomold Tooling @ University of Maryland College Park
The objective of this research is to develop a novel multi-stage molding process for creating a new class of articulated devices that have mesoscopic features essential to the miniaturization of products in a cost-competitive manner. The approach that will be employed consists of several steps. First, interfacial adhesion phenomena encountered during the multi-stage molding process will be characterized and their relationship to process variables will be established. This knowledge will be utilized to explore alternative ways to limit adhesion at interfaces and hence create articulated joints by easily separating discrete components without breaking them. Second, viability of various cavity shape change methods and ejection mechanisms will be assessed for realizing mesoscopic joints using multi-stage molding. This knowledge will be utilized to optimize tooling configurations for making mesoscopic articulated devices. Finally, an improved understanding of the influence that process parameters for microscale electrical discharge machining have on the resulting surface characteristics and dimensional accuracies will be developed. This knowledge will be utilized to create mold inserts to be used in the new molding process that will be essential to defining the limitations on the size of the mesoscopic features. The proposed project is expected to have the following broader impacts. First, for mesoscopic articulated devices that can be manufactured using the new molding process, the process can be easily scaled down in size and scaled up in production quantity. Hence, this research is expected to enable new possibilities for miniaturizing products. Second, the new molding process will significantly reduce assembly operations and make manufacturing significantly less labor-intensive. Therefore manufacturing of mesoscopic devices can be done quickly and easily inside the US in a cost-competitive manner. Therefore the proposed research effort will enhance the competitiveness of the US manufacturing sector. Finally, the research results will be integrated in the manufacturing curriculum to educate a new generation of engineers ready to exploit emerging manufacturing technologies to create new products.

The proposed work is expected to lead to: (1) reduction in training cost by eliminating one-on-one training, and reducing the use of physical prototypes, and (2) better assembly designs by ensuring ease-of-assembly. Efficient and effective training methods will lead to a more agile workforce that is capable of quickly adapting to the changing requirements of the manufacturing industry. In addition, the planned research and education integration activities and outreach activities will: (1) familiarize graduate, undergraduate, and high school students with the use of virtual assembly and model simplification technologies, and (2) increase awareness among industry about potential usage of virtual assembly on low cost personal virtual environments.

Cdi-Type I: High-Performance Simulations and Interactive Visualization For Automated Nanoscale Assembly @ University of Maryland College Park
Assembling nanoscale components to make functional devices remains a grand challenge despite rapid advances in imaging, measurement, and fabrication at the nanoscale. While manipulation techniques for nanocomponents are finally emerging they currently lack automation. The lack of automation seriously limits the rate at which new nanocomponent-based devices can be invented. In order to develop automated real-time planning algorithms, we need to develop a fundamental understanding of the interaction of nanocomponents with trapping fields. Understanding different ways in which components can interact with the trap requires dense sampling of the planning parameter space using millions of computationally intensive simulation runs. The proposed project will focus on (1) development of GPU-based simulation infrastructure for simulating trap and nanocomponent interactions, (2) development of algorithms for automatically constructing simplified assembly process models from simulation data, (3) development of visualization tools for enhancing the understanding of the nanoscale assembly processes, (4) identification and characterization of real-time motion planning strategies for nanoscale assembly processes, and (5) integration of the proposed the research results with education and wider dissemination.
The proposed work will lead to a reliable, efficient, and automated assembly process for fabricating nanocomponent-based devices. We expect that this assembly process will enable nanotechnology researchers to explore new design possibilities in the area of nano electronics, nano photonics, and bio-inspired sensors. Automated assembly capability will also allow them to explore a large number of design options in a cost effective manner and hence accelerate discovery and invention. The proposed research will significantly reduce the need for manual assembly operations and will make nanomanipulation significantly less labor-intensive thereby facilitating the manufacturing of nanodevices in a cost-competitive manner. The proposed project will also create training and education materials in the areas of GPU-based simulations, interactive visualization at nanoscale, automated model construction, and real-time motion planning.

Nri: Collaborative Research: Enabling Risk-Aware Decision Making in Human-Guided Unmanned Surface Vehicle Teams @ University of Maryland College Park
Over the last ten years, substantial progress has been made in the development of small low-cost unmanned surface vehicles (USVs). There are a number of civilian applications where deploying a human-robot team consisting of several small USVs and one or more human supervisors can significantly reduce costs, improve safety, and increase operational efficiencies. Representative applications include remote/persistent ocean sensing, marine search and rescue, maritime operations in congested port environments, and industrial offshore supply and support. USVs face unique challenges that are not experienced by robots operating indoors, such as: the need to adhere to marine navigation rules (COLREGs); local current, wave and wind conditions that can severely reduce the dynamic range of sensors and actuators; frequent communication interruptions; and risk and urgency due to rapidly changing situations during outdoor on-water operations. This research aims to develop decision making foundations for enabling teams of humans and USVs to perform complex collaborative tasks. Advances in this area could be extremely important from both a regulatory and practical standpoint for the future deployment of USV systems. Results from this research will enable leveraging the tremendous potential of USVs by reducing the cost of deployment and operational risks in civilian applications. The integration of the research with graduate and undergraduate courses will enhance the robotics and ocean engineering curricula and enrich learning experiences of the participating students. Outreach activities will educate and inform K-12 students about career opportunities in marine robotics.
The overall goal of the proposed effort is to make advances in risk-informed decision making so that teams of USVs and human supervisors can work cooperatively on a wide variety of missions. The proposed work will develop a comprehensive distributed decision making approach by leveraging the latest advances in task coordination and assignment, planning, reactive behaviors, and control to enable the deployment of human-guided USV teams in civilian applications. Progress in these constituent components will be pursued to ensure that they are consistent with each other and to explicitly account for risk during decision making. This research will develop methodologies to model team missions to ensure that all phases of decision making will have the required information for making informed decisions. Decision making methodologies will be developed for sparse advisory control of USV teams to mitigate risks and for coordinating and assigning tasks to different USVs in the team. Algorithms will also be developed for risk-aware deliberative trajectory planning and generating and executing reactive behaviors for mitigating risks. The methods developed will be validated through on-water field experiments.
