Starry Walkway In The Netherlands Lights Up The Night

When functional engineering blends itself with design and aesthetics, the things we encounter in daily life make the world a more exciting place to be. Artist, [Daan Roosegaarde’s] solar-powered walkway was unveiled last night in Nuenen, Netherlands, illuminating a kilometer long pathway with swirling light, transforming the space visually with functionality.

If the blue and green flowing spirals look familiar, that’s because they were inspired by the painting, Starry Night by Vincent Van Gogh, who was a resident of Nuenen for part of his life. The mosaic-like shapes arranged throughout the path are coated in a special paint containing a chemical that absorbs sun light in order to glow effectively for up to ten hours over night.

starryBikepathThis project is the second installment of [Studio Roosegaarde’s] Smart Highways Research; the larger goal of which is to integrate new technology with roads in an artistically inspired approach to make commuting safer and more energy-efficient. In a few other similar incentives, [Roosegaarde] envisions using this same glowing paint for road markings as a means to help replace the need for street lights. The paint coating he proposes would also be temperature sensitive and capable of creating images to indicate to drivers when there may be ice present due to freezing. His ideas for upgraded roads include a priority lane that could recharge electric cars by means of induction coils built-in underneath them. Even cooler yet, [Roosegaarde] has also proposed the possibility of engineering trees to contain the bioluminescent qualities of some jellyfish and mushrooms so that they too can help replace costly artificial light outdoors. Since some of these technologies are set to be implemented in parts of the Netherlands in the coming years, the re-envisioned environmentally aware future could very well look like a fantasy scene from a painting.

Surfing Around On A Self-Balancing Cloud

Throughout time it’s just been plain cool to genie around from point A to B on some form of personal portable hardware. Understandably so, it was the goal of [Dane Kouttron] to modify and improve the common standard in such a way that anyone could hop on his board and ride without a period of flailing to keep balance. In his Flying Nimbus project, the rider floats aloft a single power-driven wheel that will even do the balancing bit for you.

Inspired by some interesting aluminum scraps and an old 3 phase DC servo driver, [Dane] starting conjuring ideas of combining the two in order to produce his own self balancing form of transportation. A chunky reused tire from a local go-kart track turned out to serve as his wheel of choice which would mount between the feet of the rider. After ordering a 48v hub motor and waiting for it to make its way over from China, [Dane] took the time to model all of the individual parts, motor, and wheel in CAD to figure out the needed measurements for the custom pieces he’d later fabricate to fit around them. The aluminum frame that the rider stands upon not only houses and conceals the power cells and electronics running the central wheel, it also illuminates white light from the sides to stand out at night. Along the road of troubleshooting, [Dane] eventually scored a complementary top-notch servo drive from AMC, who ultimately wanted to see his project rolling as badly as he did. There is a load of detailed documentation on the layers of problem solving that went into the project on his blog, as well as more on the hardware used by [Dane] to get the board actively balancing. Seeing the final product should further enforce that there is no better way to get around then on the likes of something you made yourself:

Nothing’s As Vain As A Phone Taking A Selfie Of Itself… With Itself

The selfie: pop culture’s most frivolous form of self-expression is also probably one of the most human acts you could find yourself doing in a day. Everyone is guilty of snapping a quick pic from time to time with the expectation that it will leave an impression on those who see it. All of the implications surrounding why we do this support our deep-seated need to sculpt an identity for ourselves using others as the hammer and chisel. So, consider how upside-down the world would feel if you caught a robot posing for a shot in the mirror? What about one whose sole function was to take selfies and post them? If this breaks your mind a little, that was the intention. This #selfie robot by artists [Radamés Ajna] and [Thiago Hersan] is the first development in a larger body of work called “memememe”, which is meant to comment on our culture’s obsession with the trending, selfing nature of social media. This specific project explores the relationship between conversation and identity in a situation where there is no second party.

selfieBOT2Hardware-wise, the #selfie bot is a Stewart platform made from six servo motors and a few pieces of carefully measured pushrod connected with swivel-ball-links. An android phone is mounted on the end effector which acts functionally as the robot’s face and eyes. To make it self-aware in a sense, [Ajna] and [Hersan] created their own recognition software with Open CV using a collection of sample images of various phones as reference points. As soon as the robot recognizes itself in the mirror as indicated by specific words flashing on its screen, it takes a picture, immediately uploading it to its own tumblr account. [Ajna] and [Hersan] have a nice description of their process on the project’s Instructable’s page which you can check out to see how they used Haar Cascades to create their custom object recognition. Additionally, if you’d fancy building your own robot to covertly place in your living room to snap pictures of other phones, you could check out their code on github.

Echo, The First Useful Home Computer Intelligence?

We’re familiar with features like Siri or Microsoft’s Cortana which grope at a familiar concept from science fiction, yet leave us doing silly things like standing in public yowling at our phones. Amazon took a new approach to the idea of an artificial steward by cutting the AI free from our peripherals and making it an independent unit that acts in the household like any other appliance. Instead of steering your starship however, it can integrate with your devices via bluetooth to aide in tasks like writing shopping lists, or simply help you remember how many quarts are in a liter. Whatever you ask for, Echo will oblige.

Screen Shot 2014-11-06 at 2.57.14 PMThe device is little more than the internet and a speaker stuffed into a minimal black cylinder the size of a vase, oh- and six far-field microphones aimed in each direction which listen to every word you say… always. As you’d expect, Echo only processes what you say after you call it to attention by speaking its given name. If you happen to be too far away for the directional microphones to hear, you can alternatively seek assistance from the Echo app on another device. Not bad for the freakishly low price Amazons asking, which is $100 for Prime subscribers. Even if you’re salivating over the idea of this chatting obelisk, or intrigued enough to buy one just to check it out (and pop its little seams), they’re only available to purchase through invite at the moment… the likes of which are said to go out in a few weeks.

The notion of the internet at large acting as an invisible ever-present swiss-army-knife of knowledge for the home is admittedly pretty sweet. It pulls on our wishful heartstrings for futuristic technology. The success of Echo as a first of its kind however relies on how seamlessly (and quickly) the artificial intelligence within it performs. If it can hold up, or prove to hold up in further iterations, it’s exciting to think what larger systems the technology could be integrated with in the near future… We might have our command center consciousness sooner than we thought.

With that said, inviting a little WiFi probe into your intimate living space to listen in on everything you do will take some getting over… your thoughts?

Make A Capacitive Clothespin Keyboard For Your IPad

Even with all the optimization and style of new technology, the keyboard is a difficult thing to replace. Touch screens just don’t deliver the tactile feedback that connects us to the medium. [Adam Kumpf] remedies this by building his own keyboard interface to work with an iPad piano app, all from craft materials you’d likely find lying around in the kitchen.

To make your own, you’d first need a bunch of clothespins which will ultimately act as your keys. [Adam] shows how to stitch the separated halves of the clothespins onto a piece of cardboard with some basic rubber bands. These tension the keys so that they can rock back and forth over a pen or pencil placed beneath them. When you press down on one end, the other lifts causing an opposing pin to press the corresponding key of the iPad, just like a hammer inside a piano. With a little aluminum foil for conductivity wrapped around the side making contact, you’ve got yourself a quick solution for your itch to rock some Chopin.

You can see how well the project works in action below in his video:

Reinventing The Wheel Makes For A Better Wheel…

When robots take over the earth, it will be important that they maneuver across various types of terrain quickly and effectively. Bipedal motion is a tricky feat to accomplish for machines, so [Carter Hurd] decided, why not invent a better wheel? Even wheels can be improved, right?

Making excellent use of the prototyping capabilities of a 3D printer, [Carter] designed a set of bulb-shaped mechanisms which act effectively to drive themselves around on a smooth surface. The bulb is split radially into a series of wedge slices which can articulate outward, transforming the robot into something of a spiky razor-beast, able to tear through piles of fall leaves or wakes of loose sand. In order to unfurl itself however, the shaft driving the central mounting plate of the wedges has to fight the robot’s own weight. To solves this, [Carter] modified his design so that the rest of the wedges would unfold around the one supporting the load, the wheels would then rotate to shift the weight, allowing the last piece to extend.

[Carter] shows a proof of concept from earlier this year, explaining his hinge design which stretches a tendon-like connector in order to tension the wedges in one state or the other. Since then it looks like his transforming wheel has evolved a bit. You can get a better view of his robot in action here :

Halloween Hack Night At Pololu

Have some servos and an Arduino lying around? It isn’t too late to get your freaky on! Last night, tech enthusiasts of Las Vegas gathered at Pololu Robotics to show off their hacks for a Halloween flavored edition of their bi-monthly robot club. These projects created by those in the community as well as the Pololu engineers themselves are fun and have a relatively short list of materials. So, if the examples below give you some inspiration, this is permission to Macgyver something together before your big Halloween party tonight…

roboFingersImpatient Severed Fingers – [Amanda] came up with a cute use for some mini servos and a zombie hand prop. The five severed fingers were attached to one end of a plastic rod. The other end was mounted to each of five servos which were laid out in the appropriate hand shape and attached to a fixed base. An Arduino running a basic sweep sketch animated the motors at slightly staggered intervals, creating a nice rolling effect. Even with the moving parts exposed this prop would be awesome to have on display, or set the ambiance with its continuous tapping…

deltaSpectorAngry Spectral Delta – [Nathan Bryant] made an actual costume for his delta robot from Robot Army. By attaching a small plastic skull to the end effector and draping a tattered piece of fabric over the rest of the mechanism he effectively transformed the delta into a little ghost with a sassy personality. The head swiftly bobbed about, all while staying parallel to the table… until it intermittently came unhinged and hung limply, which was a nice added effect!

 

exorcismBabyRobotic Exorcism Baby – This doll could turn its half skeleton, half baby face 180 degrees and then laugh at your fear. By attaching two servo motors together, [Jeremy] was able to create a pan and tilt mechanism which acted as the baby’s contorting neck and chattering jaw. The micro controller sending commands to the motors was hidden modestly under her dress.

 

shadowBoxStabby Animated Cardboard Shadowbox – Among the animatronic devices seen at the event was a shadowbox made by [Brandon] hidden in a dark conference room nearby. When one happened to walk past the seemingly unoccupied space, they’d glimpse the silhouette of an arm stabbing downward with a knife through a windowsill. Being lured in for further investigation you’d find that the shadow was being cast by some colored LEDs through a charmingly simple device. A cutout made from recycled card stock was attached to a single servo. This whole mechanism itself rocked back and forth slightly as the motor moved, which wasn’t intentional but added some realism to the motion of the stabby arm.

There were many interesting projects present last night ranging from remote-controlled skeletal arms to other reactive devices ready to deliver a scare. If you’re interested in knowing more, those made by the Pololu crew are documented on their blog. Since video does these projects better justice, you can check out a compilation of clips here:
