Artificial muscle for soft robotics: Low voltage, high hopes
Phys.org: Soft robots do a lot of things well but they're not exactly known for their speed. The artificial muscles that move soft robots, called actuators, tend to rely on hydraulics or pneumatics, which are slow to respond and difficult to store.
Dielectric elastomers, soft materials that have good insulating properties, could offer an alternative to pneumatic actuators but they currently require complex and inefficient circuitry to deliver high voltage as well as rigid components to maintain their form—both of which defeat the purpose of a soft robot.
Now, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a dielectric elastomer with a broad range of motion that requires relatively low voltage and no rigid components. They published their work recently in Advanced Materials. Cont'd...
Robot Vision vs Computer Vision: What's the Difference?
Unlike pure Computer Vision research, Robot Vision must incorporate aspects of robotics into its techniques and algorithms, such as kinematics, reference frame calibration and the robot's ability to physically affect the environment.
Anki To Release Game-changing Cozmo SDK
For developers interested in lower-level control of Cozmo, the SDK provides direct access to low-level controls such as driving the robot's treads, moving the head and lift, displaying bitmaps on his screen, reading accelerometer and gyroscope data, processing images from his camera, and communicating with the power cubes (lights, accelerometer, tap detection).
Robotics Gone Wild: 8 Animal-Inspired Machines
Thomas Claburn for InformationWeek: Among programmers, there's a principle called DRY, which stands for "Don't repeat yourself." It's an attempt to avoid writing code that duplicates the function of other code.
DRY embodies the same resistance to needless repetition as the more common idiom, "Don't reinvent the wheel."
Among those making robots, a group that includes software and hardware engineers attempts to adhere to these principles, as can be seen in designs that borrow from nature, from the evolved forms of life on Earth.
Biomimicry and bioinspired design provide a way to avoid reinventing the wheel. The biological systems of living things have been honed through eons of Darwinian user testing.
Borrowing aspects of animal physiology isn't the only option or necessarily the best option for robot designers. For some purposes, something new may be necessary. For others, biomechanically systems can't be easily duplicated. Cont'd...
Cozmo Is an Artificially Intelligent Toy Truck That's Also the Future of Robotics
CADE METZ for WIRED: HANNS TAPPEINER TYPES a few lines of code into his laptop and hits “return.” A tiny robot sits beside the laptop, looking like one of those anthropomorphic automobiles that show up in Pixar’s Cars movies. Almost instantly, it wakes up, rolls down the table, and counts to four. This is Cozmo—an artificially intelligent toy robot unveiled late last month by San Francisco startup Anki—and Tappeiner, one of the company’s founders, is programming the little automaton to do new things.
The programs are simple—he also teaches Cozmo to stack blocks—but they’re supposed to be simple. Tappeiner is using Anki’s newly unveiled software development kit—an SDK, in coder parlance—that he says even the greenest of coders can use to tweak the behavior of the toy robot. And that’s a big deal, at least according to Anki. The company claims the SDK is the first of its kind: a kit that lets anyone program such an intelligent robot, a robot that recognizes faces and navigates new environments and even mimics emotions. With the kit, Tappeiner says, “we’re trying to advance the field of robotics.” He compares the move to Apple letting people build apps for the iPhone. Cont'd...
The New Police Arsenal - Robots
Bomb robots were designed to help detonate and remove Improvised Explosive Devices (IEDs), not to deliver payloads. But the Dallas police improvised and attached a bomb delivery system to the robot.
I, Snowbot
From New York Magazine: Snowden’s body might be confined to Moscow, but the former NSA computer specialist has hacked a work-around: a robot. If he wants to make his physical presence felt in the United States, he can connect to a wheeled contraption called a BeamPro, a flat-screen monitor that stands atop a pair of legs, five-foot-two in all, with a camera that acts as a swiveling Cyclops eye. Inevitably, people call it the “Snowbot.” The avatar resides at the Manhattan offices of the ACLU, where it takes meetings and occasionally travels to speaking engagements. (You can Google pictures of the Snowbot posing with Sergey Brin at TED.) Undeniably, it’s a gimmick: a tool in the campaign to advance Snowden’s cause — and his case for clemency — by building his cultural and intellectual celebrity. But the technology is of real symbolic and practical use to Snowden, who hopes to prove that the internet can overcome the power of governments, the strictures of exile, and isolation...

Rise in Robotics Requires New Tax Approach, EU Report Warns
Linda A. Thompson for Bloomberg: European lawmakers warn that the growing use of robots and artificial intelligence may cause job losses across the continent, threatening to result in plummeting tax revenues if current tax frameworks aren't revised to account for the rise of the robotic workforce.
Practitioners told Bloomberg BNA that taxing robots as “electronic persons,” as the EU contemplates in a recent report, would hinder innovation and that other ways of taxing the value that robotics create should be explored.
The recent European Parliament Committee on Legal Affairs draft reportrecommends the European Commission adopt a resolution to require companies to report on “the extent and proportion of the contribution of robotics and AI to the economic results of a company for the purpose of taxation and social security contributions.” Its first paragraph references Frankenstein, and comes amid mounting concerns that the rise in automation and artificial intelligence in the workplace will fundamentally alter economies, destroy jobs and jeopardize social welfare programs such as social security.

Toyota's U.S. Robotics Boss Promises Results Within 5 Years
Yuri Kageyama for News Factor: The U.S. robotics expert tapped to head Toyota's Silicon Valley research company says the $1 billion investment by the giant Japanese automaker will start showing results within five years.
Gill Pratt [pictured above] told reporters that the Toyota Research Institute is also looking ahead into the distant future when there will be cars that anyone, including children and the elderly, can ride in on their own, as well as robots that help out in homes.
Pratt, a former program manager at the U.S. military's Defense Advanced Research Projects Agency, joined Toyota Motor Corp. first as a technical adviser when it set up its artificial intelligence research effort at Stanford University and MIT.
He said safety features will be the first types of AI applications to appear in Toyota vehicles. Such features are already offered on some models now being sold, such as sensors that help cars brake or warn drivers before a possible crash, and cars that drive themselves automatically into parking spaces or on certain roads.
"I expect something to come out during those five years," Pratt told reporters recently at Toyota's Tokyo office of the timeframe seen for the investment. Cont'd...
Boston Dynamics posts video of one of the quietest robots ever being built
John DiPietro for NHVoice: Lately, Boston Dynamics has released a new video of its robot called Mini Spot. In the video, the robot is seen running around outside, planning around objects in a home and climbing up stairs. The best part of the video is how delicately the robot picks up a wine glass and puts into the dishwasher.
The wine-glass act has been highlight as it could be judged as to how much skilled is the robot in handling delicate things. For robots to safely operate around humans they need to be able to sense their environment and capable of knowing how mighty they are.
Mini Spot weighs 55 lbs and is all electric and runs for around 90 minutes on a charge depending on what is it doing. The robot is having many sensors, including depth cameras, a solid state gyro and proprioception sensors in its limbs. Cont'd...

Artificial Intelligence Produces Realistic Sounds That Fool Humans
From MIT News: Video-trained system from MIT’s Computer Science and Artificial Intelligence Lab could help robots understand how objects interact with the world. Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have demonstrated an algorithm that has effectively learned how to predict sound: When shown a silent video clip of an object being hit, the algorithm can produce a sound for the hit that is realistic enough to fool human viewers.
This “Turing Test for sound” represents much more than just a clever computer trick: Researchers envision future versions of similar algorithms being used to automatically produce sound effects for movies and TV shows, as well as to help robots better understand objects’ properties...

Teaching robots the physics of sliding and pushing objects
Jiaji Zhou for RoboHub: The Manipulation Lab at the CMU Robotics Institute proposes a computational model that relates an applied robot action to the resultant object motion. Their research won the Best Conference Paper Award atICRA 2016.
Understanding the mechanics of manipulation is essential for robots to autonomously interact with the physical world. One of the common manipulation scenarios involves pushing objects in a plane subject to dry friction. We propose a planar friction (force-motion) model that relates an applied robot action to the resultant object motion. Cont'd...
Amazon's $775 million deal for robotics company Kiva is starting to look really smart
Eugene Kim for Business Insider: It wasn't until 2014 that Amazon really started to use the machines made by Kiva, the robotics company it bought for $775 million in 2012. Kiva makes robots that automate the picking and packing process at large warehouses.
But in the short two years they've been deployed across Amazon's warehouses, Kiva's robots have been a real cost saver, according to a new note published by Deutsche Bank on Wednesday.
The note says Kiva robots have cut operating expenses by about 20%, quoting Amazon exec Dave Clark, adding that it would translate to roughly $22 million in cost savings for each fulfillment center.
Additionally, Deutsche Bank estimates Amazon could cut another $800 million in one-time cost savings once it deploys more Kiva robots across the 110 fulfillment centers that don't have them yet. Amazon uses Kiva robots in only 13 of its fulfillment centers currently. Cont'd...
