We present CODA, an interactive software tool, implemented on top of Autodesk Fusion 360, that helps novice modelers with designing well-constrained parametric 2D and 3D CAD models. We do this by extracting relations that are present in the design but are not yet enforced by constraints. CODA presents these relations as suggestions for constraints and clearly communicates the implications of every constraint by rendering animated visualizations ...

Over the past two decades, many toolkits for prototyping interactive and ubiquitous electronic devices have been developed. Although their technical specifications are often easy to look up, they vary greatly in terms of design, features and target audience, resulting in very real strengths and weaknesses depending on the intended application. These less technical characteristics are often reported inconsistently, if at all. In this paper we ...

(a) (b) (c) Figure 1: AirTouch augments 3D-printed objects to enable touch-sensitivity. It works by detecting the pressure change resulting from users blocking tiny air outlets fabricated into the objects. (a) Three active animal objects: each has touch points on its ear, nose, foot, and back. The same machine learning model works interchangeably with all three. (b) Structure inside the bunny, illustrated via computer rendering. The external ...

We present SoftMod, a novel modular electronics kit consisting of soft and flexible modules that snap together. Unlike existing modular kits, SoftMod tracks the topology of interconnected modules and supports basic plug-and-play behavior as well as advanced user-specified behavior. As such, the shape of a SoftMod assembly does not depend on the desired behavior and various 2D and 3D electronic systems can be realized. While the plug-and-play ...

We present a novel DIY fabrication workflow for prototyping highly flexible circuit boards using a laser cutter. As our circuits consist of Kapton and copper, they are highly conductive and thus support high-frequency signals, such as I2C. Key to our approach is a laser machine that supports both a CO2 laser as well as a fiber laser to precisely process respectively Kapton and copper. We also show how the laser cutter can cure soldering paste to ...

We present Rataplan, a robust and resilient pixel-based approach for linking multi-modal proxies to automated sequences of actions in graphical user interfaces (GUIs). With Rataplan, users demonstrate a sequence of actions and answer human-readable follow-up questions to clarify their desire for automation. After demonstrating a sequence, the user can link a proxy input control to the action which can then be used as a shortcut for automating a ...

In this letter, we address the challenge of sensor fusion in Soft Robotics for estimating forces and deformations. In the context of intrinsic sensing, we propose the use of soft capacitive sensing to find a contact's location, and the use of pneumatic sensing to estimate the force intensity and the deformation. Using a FEM-based numerical approach, we integrate both sensing streams and model two Soft Robotics devices we have conceived. These ...

supports casual makers in designing and fabricating constructions with power tools. Starting from a digital version of the construction, JigFab achieves this by generating various types of constraints that configure and physically aid the movement of a power tool. Constraints are generated for every operation and are custom to the work piece. Constraints are laser cut and assembled together with predefined parts to reduce waste. JigFab’s ...

We present StackMold, a DIY molding technique to prototype multi-material and multi-colored objects with embedded electronics. The key concept of our approach is a novel multi-stage mold buildup in which casting operations are interleaved with the assembly of the mold to form independent compartments for casting different materials. To build multi-stage molds, we contribute novel algorithms that computationally design and optimize the mold and ...
