New Algorithms Enable Self-Assembling, Printable Robots

In two new papers, MIT researchers demonstrate the promise of printable robotic components that, when heated, automatically fold into prescribed three-dimensional configurations.One paper describes a system that takes a digital specification of a 3-D shape — such as a computer-aided design, or CAD, file — and generates the 2-D patterns that would enable a piece of plastic to reproduce it through self-folding.The other paper explains how to build electrical components from self-folding laser-cut materials. The researchers present designs for resistors, inductors, and capacitors, as well as sensors and actuators — the electromechanical “muscles” that enable robots’ movements.“We have this big dream of the hardware compiler, where you can specify, ‘I want a robot that will play with my cat,’ or ‘I want a robot that will clean the floor,’ and from this high-level specification, you actually generate a working device,” said Daniela Rus, the Andrew and Erna Viterbi Professor of Electrical Engineering and Computer Science at MIT.SourceAlso: Learn about Self-Assembling, Flexible, Pre-Ceramic Composite Preforms.

Motion-Sensing Keyboard Lets Users Hover and Swipe

Microsoft engineers have developed a new type of augmented mechanical keyboard, sensing rich and expressive motion gestures performed both on and directly above the device. A low-resolution matrix of infrared (IR) proximity sensors is interspersed with the keys of a regular mechanical keyboard. This results in coarse, but high frame-rate motion data.

Cyberlearning Platforms Improve Design Collaboration

Two new "cyberlearning" platforms allow non-artists to create illustrations rivaling the work of expert designers. The platforms sidestep a key creative barrier by eliminating the need for drawing skills in developing new designs. "Non-experts are becoming more empowered and interested in means of creative self-expression," said Karthik Ramani, Purdue University's Donald W. Feddersen Professor of Mechanical Engineering. "More importantly, I think this is the beginning of a new field of computer-supported creativity where you are extending the human mind." The new platforms — called skWiki (pronounced squeaky) and Juxtapoze — may usher in a new era of digital-scribbling and creative collaboration. The platforms operate on servers and do not require users to install any software. The skWiki platform allows collaboration with multimedia, including text, sketches, photos and "vector images" important for computer-aided design and other applications.

Gridded Atmosphere Products from GPS Radio Occultation Measurements with Bayesian Interpolation Technique

NASA’s Jet Propulsion Laboratory, Pasadena, California GPS radio occultation measurements are vital for climate monitoring and atmospheric temperature change detection. However, the data are irregularly distributed in space and time, which makes it inconvenient for many applications.

Goddard Mission Services Evolution Center Compliance Test Suite

Goddard Space Flight Center, Greenbelt, Maryland To reduce the cost of building specialized interfaces, missions can adopt Goddard Mission Services Evolution Center (GMSEC) technologies and applications. Assurances need to be made that application implementation should follow the GMSEC messaging standards. The GMSEC Interface Specification Document (ISD) sets forth definitions for all GMSEC message types.

NASA Experiment Designer: A Tool for Running Scientific Workflows

The NASA Experiment Designer (NED) is a client-server application that enables end-to-end support for driving long-running scientific computer simulations such as climate and weather models. The tool provides a friendly, single point of entry for configuring parameters associated with the workflow for model experiments and related preprocessing/postprocessing tasks.

SensorWeb Campaign Manager API Client

This software was designed to automate delivery of tasking requests to a central queue, enabling integrated observation scenarios across multiple assets. It is a JAVA code application that enables machine-to-machine access between a client platform and the Campaign Manager application program interface (API) to post tasking requests for satellites that the Campaign Manager can access. The Campaign Manager tasks satellites via moderated tasking queue in which the operations team allows or denies requests.
