From Alex Churchill: In the discussion on this site I assemble a Universal Turing Machine from Magic: the Gathering cards. But doesn't Magic involve the players making lots of choices? Normally, yes, it does. But occasionally in normal gameplay you get a sequence of three or four events in a row that are forced to happen by the cards and the rules of the game. The machine below just extends this idea to millions of forced choices in a row. The idea of my Magic Turing machine is that the players do nothing at all, except when the game offers them a choice. Once the in-game "machine" has started, processing continues without requiring any choices from the players, with one category of exceptions: Some of the cards in the machine say "You may [do X]. If you do, [Y happens]." In these cases, the machine arranges that the players will be able to do X, in precisely one way. It just requires the players to always choose to take the game up on any options they're offered... ( cont'd )

From 7Bot's Kickstarter campaign: In 2014, two of us co-founded project uArm with other two makers. There we received a lot of feedback from our Angel backers: More axis for more powerful applications, and more controlling dimensions (force control, speed control and flexible-joint). More rugged material rather than Acrylic, muscular servos hardly to be burned out. More intelligent API. Better inverse kinematics and path planning algorithms to make the movement more precise and smooth. More accessories and various of end-effectors. Our custom servos with precise position feedback allow you to quickly set it up and operate in teaching mode without any codes. In this mode, you can simply drag each joint of the robot to a serious of desired way points. The movements will be recorded, and could be replayed in an optimized path. A multi-platform supported 3D visualization application will be provided for you to manipulate the 7Bot Arm intuitively. With our 3D visualization application, you can easily set and read the position of each joint separately with real-time graphic interface. If you have two 7Bot Arms, you can build this amazing Humanoid robot -7Bot Arm Dual: Estimated shipping date is January 2015... (7Bot's Kickstarter campaign)

Animated retelling of a Buckminster Fuller story and Ephemeralization (doing more with less):
Bot-maker Savioke announces an open-source wrapper for Intel's RealSense Camera, adding another low-cost 3D sensing solution to the roboticist's toolkit. The wrapper will allow developers to make use of the RealSense Camera, which enables robots to sense rich three-dimensional environments. "Intel RealSense Cameras bring great low-cost depth sensing to robotics, in a platform that is widely available and easy to integrate using ROS," says Steve Cousins, CEO of Savioke. Until recently, bot makers looking to incorporate 3D sensing on the cheap have relied on a sensor made by Israeli company PrimeSense. But in late 2013 PrimeSense was acquired by Apple for $350M, an indication of just how much potential the Cupertino-based giant sees in 3D sensing technology. Since the acquisition, robot developers have been eager for a flexible and cheap depth sensor. Intel, meanwhile, is making an aggressive move into the world of robotics, and the company was thrilled to offer ROS support for RealSense.
From the Instapainting Blog: Over the past three weeks I’ve been working on a robotic painter to research the area of mechanical artwork reproduction and automated picture to painting creation for Instapainting.com and the print store e-commerce platform A Manufactory . The initial prototype was built in about 3 weeks, and currently does mechnical reproductions. The AI painting mode which will paint a photograph will follow in the next post (putting some finishing touches on it)... ...The current prototype operates on 3 dimensions: X, Y, and a Z axis for pen pressure from the Wacom tablet. The artist can control the motion from a Wacom tablet and, for the most part, it’s lag-free. Every stroke is recorded so that it can be played back. You can see both the intitial painting and the playback in the video below... ( full post )
By Dominic Basulto for the Washington Post: Researchers at MIT have just unveiled the ability to 3-D-print beautiful glass objects. While humanity has been forming, blowing and molding glass objects for more than 4,500 years, this is the first time that a 3-D printer has been used to process glass from a molten state to an annealed product. Obviously, there are some purely aesthetic applications here, as in the potential for epic blown glass art. Think museum-worthy glass objects worthy of Dale Chihuly. In fact, the MIT team — a collaborative team of researchers that includes the MIT Media Lab’s Mediated Matter group, the MIT Glass Lab and MIT’s Mechanical Engineering Department — plan to display a few of their beautiful objects at an upcoming exhibition at the Cooper Hewitt, Smithsonian Design Museum in 2016. But the applications go beyond just beautiful new designs that might be created via 3-D printers one day. As the MIT research team points out in a forthcoming paper for the journal 3-D Printing and Additive Manufacturing, “As designers learn to utilize this new freedom in glass manufacturing it is expected that a whole range of novel applications will be discovered.” That’s the real future potential of glass 3-D printing — the ability to create objects and applications that do not exist today.

Mike Elgan for Computer World: Consumer drone technology is barely taking off, and already a harsh public backlash is growing. Your typical garden variety consumer drone is lightweight, battery operated, has four propellers and is controlled by a smartphone. Most have cameras and beam back live video, which can be recorded for posterity. Some have high-quality HD cameras on them, and from that high vantage point can take stunning photos and videos. Drones are fun. They're exciting. They're accessible. But increasingly, they're becoming unacceptable. I'm sensing a growing backlash, a kind of social media pitchfork mob against drones and drone fans. It's only a matter of time, and not much time, before it will be politically incorrect to express any kind of enthusiasm for drones in polite company. I fear that many are about to embark on an "everybody knows drones are bad" mentality that will suppress the nascent industry and spoil this innovative and exhilarating technology. Here's what's driving the coming backlash: Cont'd...
From AMREL: You know how the stuntmen make fast cars drift in action movies? Have you ever wanted to make a remote-controlled toy car drift like that? Of course you have. If there ever were awards for endeavors that sound silly, but is actually technically interesting, then the folks at MIT’s Aerospace Controls Lab would surely be nominated. Unmanned systems are rarely fully autonomous. Instead, researchers are pursuing “sliding” autonomy, i.e. an operator retains control, while some behaviors are made autonomous. Aerospace Controls Lab decided to teach a remote-control toy car how to autonomously drift. They started by running their learning algorithm through simulations. Information from these simulations was transferred to performance modifiers. When the car was run through its drifting actions in reality, the algorithm was constantly modified. The result is a car that can maintain drifting in a full circle even when salt is added to the floor, or another vehicle interferes with it.
From Techcrunch: Y Combinator-backed Auro Robotics is currently testing their driverless shuttle system at several universities, and is actually beginning to deploy shuttles on the campus of Santa Clara University. The company is also planning to expand to other markets like amusement parks, retirement communities and small islands, with some projects in those spaces already set to take off “in the later part of this year.” Auro has chosen to focus on these small, contained environments largely because they are controlled by private corporations, and thus are not subject to the heavy government regulation that Google and other companies are stuck behind with their driverless cars... ( full article ) From Auro Robotics: How does it work Auro Prime uses latest technology to ensure safe navigation even on busy roads. The vehicle is equipped with Lasers, camera, Radar and GPS providing it complete 360 degree vision under all environment situations. The shuttles relies on a prior 3D map of the environment, which is created once in the lifetime at the beginning. In all subsequent runs, it uses this 3D map to localise itself and interpret road topography. Passengers can input their destinations through a simple to use touch screen mounted on the vehicle, or through their mobile app. The underlying software automatically figures out the optimum high-level route to reach safely to the destination...

From Michael Porter at Clemson University: Seahorse tails are organized into square prisms surrounded by bony plates that are connected by joints. Many other creatures, ranging from New World monkeys to rodents, have cylindrical tails. Researchers wanted to know whether the square-prism shape gives seahorse tails a functional advantage. To find out, the team created a 3D-printed model that mimicked the square prism of a seahorse tail and a hypothetical version that was cylindrical. Then researchers whacked the models with a rubber mallet and twisted and bent them. Researchers found that the square prototype was stiffer, stronger and more resilient than the circular one when crushed. The square prototype was about half as able to twist, a restriction that could prevent damage to the seahorse and give it better control when it grabs things. Both prototypes could bend about 90 degrees, although the cylindrical version was slightly less restricted... (cont'd)
From CyPhy LVL 1 Drone Kickstarter: Our drone never tilts, allowing it to snap perfect pictures and stable video every time. By eliminating tilting, the drone handles intuitively, with an unrivaled out-of-the-box experience. Thanks to its special shape, our LVL 1 simplifies aerial photography. There’s no complex, expensive stabilization mount or vulnerable camera. You’ll take stunning pictures with ease. CyPhy Works, founded by iRobot co-founder Helen Greiner, has been making tethered drones for industrial application. These drones were designed to fly 24/7 in all types of wind and weather. While Dr. Kenneth Sebesta was optimizing our drones’ hovering, he came up with a breakthrough. He realized that with just the right twist angle of the arms and a precise amount of added dihedral — plus a lot more fancy math — we could achieve level flight for the first time on a multi-rotor drone... $495 ( Kickstarter )
