MIT's Cheetah Robot Runs Untethered 21

An anonymous reader writes: It's easy to make a robot walk, but hard to keep it from falling over. We've seen a number of crazy robot prototypes, but they're usually tethered and/or stuck on a treadmill. Now, researchers from MIT have developed an algorithm that allows their giant robot cheetah to run around outdoors at up to 10mph. They expect the robot to eventually hit speeds of 30mph. "The key to the bounding algorithm is in programming each of the robot's legs to exert a certain amount of force in the split second during which it hits the ground, in order to maintain a given speed: In general, the faster the desired speed, the more force must be applied to propel the robot forward. ... Kim says that by adapting a force-based approach, the cheetah-bot is able to handle rougher terrain, such as bounding across a grassy field." The MIT cheetah-bot also runs on a custom electric motor, which makes it significantly quieter than gas-powered robots. "Our robot can be silent and as efficient as animals. The only things you hear are the feet hitting the ground."

The Growing Illusion of Single Player Gaming 63

Posted by Soulskill
from the forcing-introverts-to-play-with-introverts dept.
An anonymous reader writes: Multiplayer modes used to be an extra part of most games — an optional addition that the developers could build (or not) as they saw fit. These days, it's different: many games are marketed under the illusion of being single-player, when their focus has shifted to an almost mandatory multiplayer mode. (Think always-online DRM, and games as services.) It's not that this is necessarily bad for gameplay — it's that design patterns are shifting, and if you don't like multiplayer, you're going to have a harder time finding games you do like.

The article's author uses a couple recent major titles as backdrop for the discussion: "With both Diablo III and Destiny, I'm not sure where and how to attribute my enjoyment. Yes, the mechanics of both are sound, but given the resounding emptiness felt when played solo, perhaps the co-op element is compensating. I'd go so far as to argue games can be less mechanically compelling, so long as the multiplayer element is engaging. The thrill of barking orders at friends can, in a way, cover design flaws. I hem and haw on the quality of each game's mechanics because the co-op aspect literally distracted me from engaging with them to some degree."

Schizophrenia Is Not a Single Disease 94

Posted by Soulskill
from the inconsistency-explained dept.
An anonymous reader writes: New research from Washington University has found that the condition known as schizophrenia is not just a single disease, but instead a collection of eight different disorders. For years, researchers struggled to understand the genetic basis of schizophrenia. This new method was able to isolate and identify the different conditions (each with its own symptoms) currently classified under the same heading (abstract, full text). "In some patients with hallucinations or delusions, for example, the researchers matched distinct genetic features to patients' symptoms, demonstrating that specific genetic variations interacted to create a 95 percent certainty of schizophrenia. In another group, they found that disorganized speech and behavior were specifically associated with a set of DNA variations that carried a 100 percent risk of schizophrenia." According to one of the study's authors, "By identifying groups of genetic variations and matching them to symptoms in individual patients, it soon may be possible to target treatments to specific pathways that cause problems."

Sci-Fi Authors and Scientists Predict an Optimistic Future 108

Posted by Soulskill
from the roddenberry-approved dept.
An anonymous reader writes: A few years ago, author Neal Stephenson argued that sci-fi had forgotten how to inspire people to do great things. Indeed, much of recent science fiction has been pessimistic and skeptical, focusing on all the ways our inventions could go wrong, and how hostile the universe is to humankind. Now, a group of scientists, engineers, and authors (including Stephenson himself) is trying to change that. Arizona State University recently launched Project Hieroglyph, a hub for ideas that will influence science fiction to be more optimistic and accurate, and to focus on the great things humanity is capable of doing.

For example, in the development of a short story, Stephenson wanted to know if it's possible to build a tower that's 20 kilometers tall. Keith Hjelmsad, an expert in structural stability and computational mechanics, wrote a detailed response about the challenge involved in building such a tower. Other authors are contributing questions as well, and researchers are chiming in with fascinating, science-based replies. Roboticist Srikanth Saripalli makes this interesting point: "If the government has to decide what to fund and what not to fund, they are going to get their ideas and decisions mostly from science fiction rather than what's being published in technical papers."

Funding Tech For Government, Instead of Tech For Industry 39

Posted by Soulskill
from the imagine-an-iphone-developed-by-the-government dept.
An anonymous reader writes: If you're a creative engineer looking to build a product, you're probably going to end up starting your own business or joining an established. That's where ideas get funding, and that's where products make a difference (not to mention money). Unfortunately, it also siphons a lot of the tech-related talent away from government (and by extension, everybody else), who could really benefit from this creative brilliance. That's why investor Ron Bouganim just started a $23 million fund for investment in tech companies that develop ideas for the U.S. government. Not only is he hoping to transfer some of the $74 billion spent annually by the government on technology to more efficient targets, but also to change the perception that the best tech comes from giant, entrenched government contractors.

Well it's a shame then the FCC rules under discussion would have nothing whatsoever to do with that,.

Gosh, I wonder what you are getting if it's not at all what you thought. I wonder what you are getting from an agency intertwined with the cable companies, when you ask them to provide regulation from same companies... Perhaps utterly the opposite of what you wanted?

Court: Car Dealers Can't Stop Tesla From Selling In Massachusetts 92

Posted by Soulskill
from the court-order-to-play-well-with-others dept.
curtwoodward writes: Many states have laws that prevent car manufacturers from operating their own dealerships, a throwback to the days when Detroit tried to undercut its franchise dealers by opening company-owned shops. But dealers have taken those laws to the extreme as they battle new competition from Tesla, which is selling its cars direct to the public. In some states, dealers have succeeded in limiting Tesla's direct-sales model. But not in Massachusetts (PDF): the state's Supreme Court says the dealers don't have any right to sue Tesla for unfair competition, since they're not Tesla dealers. No harm, no foul.

Court Rules the "Google" Trademark Isn't Generic 100

Posted by samzenpus
from the what's-in-a-name dept.
ericgoldman writes Even though "googling" and "Google it" are now common phrases, a federal court ruled that the "Google" trademark is still a valid trademark instead of a generic term (unlike former trademarks such as escalator, aspirin or yo-yo). The court distinguished between consumers using Google as a verb (such as "google it"), which didn't automatically make the term generic, and consumers using Google to describe one player in the market, which 90%+ of consumers still do.

SparkFun Works to Build the Edison Ecosystem (Video) 56

Posted by Roblimo
from the more-tiny-electronics-for-makers-and-builders-to-make-and-build-with dept.
Edison is an Intel creation aimed squarely at the maker and prototype markets. It's smaller than an Arduino, has built-in wi-fi, and is designed to be used in embedded applications. SparkFun is "an online retail store that sells the bits and pieces to make your electronics projects possible." They're partnering with Intel to sell the Edison and all kinds of add-ons for it. Open source? Sure. Right down to the schematics. David Stillman, star of today's video, works for SparkFun. He talks about "a gajillion" things you can do with an Edison, up to and including the creation of an image-recognition system for your next homemade drone. (Alternate Video Link)
