Capable Modular Robots November 9, 2019

 MIT’s Computer Science and Artificial Laboratory’s M-Block robots can self-assemble into different structures. The little cubes (in development over the last six years) have gained the ability to jump, flip, spin, and recognize each other. A barcode-like system on each face of each cube, allowing them to identify the other cubes around them.

The engineers wanted to see if the M-Blocks could (for example) form a straight line or form a random structure using the new communication algorithms. They waited to see if the blocks could determine how they were connected, and then what direction they would need to move to create that line. They found that 90% of the block swarm knew which motion and guidance to move to accomplish the task. I’m curious to know what the other 10% did…

Engineers hope to create a more substantial swarm of blocks (>16) that can assemble to form more complex structures with new capabilities.

3D-Printed Flexible Piezoelectric Element January 24, 2019

Mechanical engineers develop process to 3D print piezoelectric materials

New methods to 3D print piezoelectric materials that can be custom-designed to convert movement, impact and stress from any directions to electrical energy have been published in Nature Materials.  The materials can also be activated — providing the next generation of intelligent infrastructures and smart materials for tactile sensing, impact and vibration monitoring, energy harvesting, and other applications. Unlike conventional piezoelectrics, where electric charge movements are prescribed by the intrinsic crystals, the new method allows users to prescribe and program voltage responses to be magnified, reversed or suppressed in any direction.

A factor in current piezoelectric fabrication is the natural crystal used. At the atomic level, the orientation of atoms are fixed. The researchers produced a substitute that mimics the crystal but allows the lattice orientation to be altered by design.

“We have synthesized a class of highly sensitive piezoelectric inks that can be sculpted into complex three-dimensional features with ultraviolet light. The inks contain highly concentrated piezoelectric nanocrystals bonded with UV-sensitive gels, which form a solution — a milky mixture like melted crystal — that we print with a high-resolution digital light 3D printer”.

The material has sensitivities 5-fold higher than flexible piezoelectric polymers. The stiffness and shape of the material can be tuned and produced as a thin sheet resembling a strip of gauze, or as a stiff block. “We have a team making them into wearable devices, like rings, insoles, and fitting them into a boxing glove where we will be able to record impact forces and monitor the health of the user,” said the chief investigator Zheng.

The team has printed and demonstrated smart materials wrapped around curved surfaces, worn on hands and fingers to convert motion, and harvest the mechanical energy, but the applications go well beyond wearables and consumer electronics.

“Traditionally, if you wanted to monitor the internal strength of a structure, you would need to have a lot of individual sensors placed all over the structure, each with a number of leads and connectors,” said Huachen Cui, a doctoral student of Zheng’s and the first author of the Nature Materials paper. “Here, the structure itself is the sensor — it can monitor itself.”

If you haven’t seen this, I recommend viewing full-sized, with the ambient music provided…or Pink Floyd.

You know you want to.

Package Installers for Windows and MacOS November 6, 2018

I have been forced at gunpoint to use a Mac for the last six weeks at my newest place of employment, and not without a few tears. I had to learn to install IntelliJ, NetBeans and Eclipse (already had that one) for MacOS. The company which enslaves me uses MacOS’ Self Service app, from which I installed Homebrew. Homebrew does every installation you could possibly desire (well, nearly) and I installed in short order git, gradle, Java and IntelliJ–all correctly and findably by each other, managing the pathname (or whatever they are called in MacOS). I must say, this makes first-day setup for the engineers much quicker, and much simpler. Good thing too, since the poor sods are going to be working with a bewildering variety of the manifold technologies which enable the hydra-headed beast which is my employer.

It turns out that Homebrew is a MacOS-only product; but there are several package installers which can work with Windows, such as Scoop,

 

Chocolatey and Npackd,  I quite liked Scoop (hence the Youtubery), but you may wish to try the others.  Good luck; for your more complex setups this can be a real timesaver.

I enjoyed this immensely, but it is about one in the morning and I have been up since about five cleaning house and preparing for my next Great Adventure.

 

I am probably punchy.

Training Neural Networks to Write Bach in a Day! March 24, 2017

Fascinating bit of video here as Our Hero (not me, in this case) takes Bach (and later Mozart) MIDI files, creates an 88-character ASCII-character alphabet from them and trains a Recurrent Neural Network to output similar sequences.

The results (and a lot of the process) is shown in the video above.  Take your time and watch the whole thing; I wonder how long he would have to train the RNN to start outputting Baroque Muzak continually?

But that’s just the medication talking.  Here’s a delightful little romance featuring a youngster who longs for death.

Of course, he eventually gets his heart’s desire.
