TL;DR: Ulysses allows for the integration of a collection of individual CAD tools into a design automation system that will execute a codified design methodology and allows the designer to interrupt the design process at any time and take control.
Abstract: Ulysses is a VLSI computer-aided-design (CAD) environment that effectively addresses the problems associated with CAD tool integration. Specifically, Ulysses allows for the integration of a collection of individual CAD tools into a design automation (DA) system that will execute a codified design methodology. Ulysses can track the multiple partial designs that result during a complete design cycle. Furthermore, Ulysses allows the designer to interrupt the design process at any time and take control. An example involving a silicon compilation task is presented to illustrate the ability of Ulysses to execute a sequence of CAD tools automatically to generate a viable layout for an IC. This example also illustrates Ulysses' ability to recover from CAD tool failures that may result if a layout cannot be completed due to routing channel congestion or overconstrained leaf-cell boundary conditions. >

TL;DR: This work presents PaperPulse, a design and fabrication approach that enables designers without a technical background to produce standalone interactive paper artifacts by augmenting them with electronics.
Abstract: We present PaperPulse, a design and fabrication approach that enables designers without a technical background to produce standalone interactive paper artifacts by augmenting them with electronics. With PaperPulse, designers overlay pre-designed visual elements with widgets available in our design tool. PaperPulse provides designers with three families of widgets designed for smooth integration with paper, for an overall of 20 different interactive components. We also contribute a logic demonstration and recording approach, Pulsation, that allows for specifying functional relationships between widgets. Using the final design and the recorded Pulsation logic, PaperPulse generates layered electronic circuit designs, and code that can be deployed on a microcontroller. By following automatically generated assembly instructions, designers can seamlessly integrate the microcontroller and widgets in the final paper artifact.

TL;DR: The authors attempted to improve model interconnectivity by enhancing the computer-aided design model with spatially related non-geometric data to enable both model authors, and consumers to utilize information inside the CAD tool which traditionally would have existed in separate software.
Abstract: The concept of the digital twin calls for virtual replicas of real world products. Achieving this requires a sophisticated network of models that have a level of interconnectivity. The authors attempted to improve model interconnectivity by enhancing the computer-aided design model with spatially related non-geometric data. A tool was created to store, visualize, and search for spatial data within the computer-aided design tool. This enables both model authors, and consumers to utilize information inside the CAD tool which traditionally would have existed in separate software.

TL;DR: The design effort comprises considerations of the number of driving actuators for controllability, body structure for both weight minimization and rigidity, and overall compactness of the robot design, resulting in the development of the spherical four-bar transmission mechanism.
Abstract: In this work we present the design of a scalable, controllable, miniature flapping wing robot. The design effort comprises considerations of the number of driving actuators for controllability, body structure for both weight minimization and rigidity, and overall compactness of the robot design. This results in the development of the spherical four-bar transmission mechanism, with a single-wing prototype experimentally characterized. A dual-wing robot design manufactured via the smart composite microstructures technique is presented, featuring independent wing actuation. Finite-element analysis of the final airframe design is presented, ensuring vibration modes out of the operation range of the platform and high rigidity. A working prototype is manufactured and experiments are conducted characterizing the robot's lift production capabilities and ensuring minimal wing coupling. A scaling law of the proposed design is presented based on momentum theory, predicting an increase of the lift/weight ratio with decreasing size. An optimization methodology for the parameters of a scaled down prototype is presented, based on a developed theoretical simulation and design tool. Finally, a 1/2 scaled down prototype using the optimized parameters is built and tested, featuring a lift/weight ratio of 3/8.
