Embodied logic: Using stimuli-responsive materials and geometric principles to create smart objects

A new paper in Nature describes the US-Army-funded research of U Penn materials scientists to create a new generation of 3D printed "smart objects" whose geometry and materials enable them to interact with their environments without having to use embedded computers, sensors or actuators.

Explainer video on how to build a Dyson Sphere

The latest explainer video from Kurzgesagt – In a Nutshell examines what it would take to actually build a crazy cool idea conceived by Princeton physicist Freeman Dyson - a photovoltaic shell (or, less ambitiously, a satellite swarm of mirrors that focus the star's energy to a collector) that envelops a star in order to capture its energy.

Bricks made from human urine

University of Cape Town researchers created the world's first "bio-bricks" made from sand, bacteria, and human urine collected from special toilets in the engineering school's bathrooms. From The Guardian:

Bio-bricks are created through a natural process called microbial carbonate precipitation, said (project supervisor and water quality engineering lecturer Dyllon) Randall, similar to the way seashells are formed. Loose sand, which has been colonised with bacteria that produces urease, is mixed with the urine. Urease breaks down the urea in the urine, producing calcium carbonate, which cements the sand into shape.

While regular bricks are kiln-fired at temperatures of 1,400C and produce large amounts of carbon dioxide, the bio-bricks do not require heat.

“If a client wanted a brick stronger than a 40% limestone brick, you would allow the bacteria to make the solid stronger by ‘growing’ it for longer,” said Randall...

Randall described urine as liquid gold. By volume, urine accounts for less than 1% of domestic waste water, but it contains 80% of the nitrogen, 56% of the phosphorus and 63% of the potassium found in waste water.

Robots! A fantastic catalog of new species

IEEE Spectrum editor Erico Guizzo and colleagues have blown out their original Robots app into a fantastic catalog of 200 of today's fantastic species of robots. They're cleverly organized into fun categories like "Robots You Can Hug," "Robots That Can Dance," "Space Robots," and "Factory Workers." If they keep it updated, it'll be very helpful for the robot uprising. After all, you can't tell the players without a program!

Incredibly sensible notes on software engineering, applicable to the wider world

François Chollet's "Notes to Myself on Software Engineering" is posed as reminders from Chollet to himself, but they're a really wonderful list of extremely sensible advice on how collaborative projects work, how to be a good collaborator, how to build things for other people to use, and how to collaborate with future engineers and builders who will some day want to hook things up to the thing you're making.

Supersonic: a glorious new art book about the Concorde airplane

During its 1970s heyday, the Concorde, the commercial supersonic plane that did NYC to London in under three hours, wasn't just a revolution in aerospace engineering; it was an icon of industrial design, set the bar in luxury travel, and, quite literally, embodied the jet-set lifestyle. Now, my friend qnd colleague Lawrence Azerrad, the creative director of the Grammy-winning Voyager Golden Record vinyl box set we released last year, has created a glorious art book about the Concorde and its scene in the sky. The book, Supersonic: The Design and Lifestyle of Concorde, overflows with historical and technical information and stunning photos of the plane, its marketing materials, and amenities designed by the likes of Andrée Putman, Raymon Loewy, and Sir Terence Conran who wrote this book's foreword. From CNN:

Taking a branded item home was part of the experience. Anything that could be removed from the plane would be taken by passengers as a souvenir. Some of these items were particularly sought after, like those designed by Raymond Loewy, the father of industrial design who created cabin interiors for Air France.

"He used a very forward-thinking, futuristic approach for that time, down to the design of the seats, the headrests, the fabric and, probably more famously, the stainless steel flatware, which Andy Warhol would famously steal," said Azerrad. "There's a story where (Warhol) asked if the person sitting next to him was taking theirs, she said no and he took her set."

Supersonic: The Design and Lifestyle of Concorde is a magnificent celebration of the history of our in-flight future. Read the rest

Electromechanical "skin" turns everyday objects into robots

Yale engineers developed "robotic skins" from elastic sheets integrating sensors and electromechanical actuators. The idea is that most any flexible object could be transformed into a robot. Professor Rebecca Kramer-Bottiglio and her colleagues reported on their project, called OmniSkins, in the journal Science Robotics. From YaleNews:

Placed on a deformable object — a stuffed animal or a foam tube, for instance — the skins animate these objects from their surfaces. The makeshift robots can perform different tasks depending on the properties of the soft objects and how the skins are applied.

“We can take the skins and wrap them around one object to perform a task — locomotion, for example — and then take them off and put them on a different object to perform a different task, such as grasping and moving an object,” she said. “We can then take those same skins off that object and put them on a shirt to make an active wearable device.”

Marvelous scans of Leonardo da Vinci's journals

London's Victoria and Albert Museum has digitized and posted two of Leonardo da Vinci's personal notebooks. From The Art Newspaper:

“The notebooks remind us that Leonardo was as much an engineer as he was an artist. When he wrote in the early 1480s to Ludovico Sforza, then ruler of Milan, to offer him his services, he advertised himself as a military engineer, only briefly mentioning his artistic skills at the end of the list,” (says Catherine Yvard, Special Collections curator at the V&A’s National Art Library.)

Codex Forster I dates from the time Leonardo spent at the Milanese court and focuses on hydraulic engineering, featuring drawings of instruments for digging canals and for moving and raising water. It also includes a treatise on geometry and measuring solids.
