Snakebot and quadcopter combo makes for a go-anywhere rescue drone
Everyone has different ideas on what the perfect search-and-rescue robot is, and for a University of Pennsylvania Mod Lab team, it comes in the form of a snake drone-quadcopter chimera. The Hybrid Exploration Robot for Air and Land Deployment or H.E.R.A.L.D. is composed of two snake-like machines that attach via magnets to a UAV. After being carried to the site by the quadcopter, the snake bots can detach themselves, slip through the holes and cracks of a collapsed building, for instance, and slither to their destination. The researchers have been working on H.E.R.A.L.D. since 2013, but now that all its components can properly merge and work together like the robots in Power Rangers, they presented it at the 2014 IEEE/RSJ International Conference on Intelligent Robots and Systems. You can watch the machine ace the tests its creators put it through in the vid after the break, including a part where a researcher used an Xbox controller to navigate a snakebot through a pipe.
Revenge of the quadrocopters: now they move in packs (video)
In case you didn't find the original quadrocopter chilling enough, the GRASP Lab out of the University of Pennsylvania has gone and added a bit of cooperative logic to the recipe so that now multiple little drones can work together. Also upgraded with a "claw-like" gripper that allows it to pick up and transport objects, the newer quadrocopter can team up on its prey payload with its buddies, all while maintaining its exquisite balance and agility. Skip past the break to see it on video.
Selfless crazies play Desert Bus for charity
The guys behind LoadingReadyRun have a very unique way of contributing to this year's Child's Play charity: they're playing one of the worst games of all time.Desert Bus is one of several mini-games included in the never-officially-released Sega CD game Penn and Teller's Smoke and Mirrors. The Desert Bus mini-game challenges players to drive Penn and Teller's tour bus from Tuscon, Arizona to Las Vegas, Nevada... in real time... and at a maximum speed of 45 mph.It's a task that takes 8 hours to complete, and earns players one point in the game. The task can be completed back and forth as many times as the players can stomach, each time earning one point. The LoadingReadyRun team has pledged that the more money they receive, the longer they will sit and endure this painful, painful game. Over $1,000 USD have already been donated, which guarantees the masochists at least 64 hours of play-time. To see just how crazy they are, check out the gameplay footage after the break.[Thanks, Graham]
Real-life Minority Report: software for predicting murderers
Obviously the best way to prevent recidivism among violent criminals would be to simply imprison them for life following their first offense (we'd call it the "one strike and you're out" law), but thanks to that antiquated document known as the Constitution, we're forced to coddle convicts by ensuring that they don't endure "cruel and unusual punishment" to pay for their crimes. Well if we can't lock up all the muggers, jaywalkers, or tax cheats and just throw away the key, the next best option would seem to be predicting criminal behavior before it happens -- and though it sounds like straight-up science fiction, that's exactly what University of Pennsylvania criminologist Richard Berk intends to do. Using a data set consisting of 30 to 40 variables derived from anonymous Philadelphia probation department cases over a two-year period, Berk and his colleagues were able to craft an algorithm that supposedly separates those folks likely to re-offend from ex-cons not deemed to be as dangerous. The point of this program is not to make an end run around sentence limitations or to arrest people before they've committed a crime, but rather, to help probation units decide how to best allocate their resources among hundreds of potential re-offenders. To wit, each subject's variables are plugged into the software in order to create a so-called "lethality score" -- and although the aggregated data is still relatively small, Berk points out that childhood exposure to violence has already floated to the top as the single most likely predictor of murder. Another, less well-known, but equally accurate predictor: jailhouse tattoo across an inmate's chest that reads "Die, ___, Die."[Via Slashdot]
Robots learn teamwork; uprising imminent
If robots ever hope to rise up and enslave their human masters, it's going to take no small amount of teamwork to get the job done, and luckily for our future overlords, DARPA's shelling out serious loot to endow them with just the tools they'll need. The agency's latest foray into robotic empowerment comes courtesy of researchers at the University of Pennsylvania, who recently demonstrated a platform that allows multiple heterogeneous bots to communicate with one another and use a sort of AI "group think" to find and presumably terminate specified targets. In a beta test at Fort Benning's mock urban landscape, the Penn researchers deployed four so-called Clodbuster autonomous ground vehicles along with a fixed-wing UAV overhead, and tasked the team with using their cameras, GPS receivers, and wireless radios to identify and locate a series of bright orange boxes. Unfortunately, after the successful completion of their mission, the bots decided to hit up the base bar to celebrate, where after several drinks they reportedly went AWOL and were last spotted attacking orange traffic cones in downtown Columbus.
Breakthrough in ferroelectric materials could enable million-GB thumbdrives
While we have to agree with certain Engadget readers who feel that 640KB of RAM is plenty for most computing tasks, those darn scientists just keep looking for ways to stuff more and more data into smaller spaces. The latest breakthrough on the storage tip comes courtesy of researchers from Drexel and Penn, who have found a way to stabilize the simple physical property of ferroelectricity at the nano scale, making possible such obviously unnecessary densities as 12,800,000GB per cubic centimeter. Ferroelectric materials are usable as memory because they possess the ability to switch electric charges in so-called dipole moments, but before Drexel's Dr. Jonathan Spanier and colleagues decided to embed the materials in water, it had previously been impossible to screen those dipole moments at scales small enough to be useful. Don't expect to be able to buy a zillion gig, water-filled iPod anytime soon, though, as the research team still faces significant hurdles in actually assembling the nanowires that would make up such a drive with the proper density as well as developing a method of efficiently reading and writing data.
TiVo Product Watch gives you commercials on your schedule
So, you thought the whole reason to own a DVR was so that you could skip commercials? Think again. Today TiVo is rolling out the Madison Avenue-friendly Product Watch service, which lets you watch commercials on demand. Whether anyone will actually demand to watch these ads remains to be seen, but TiVo has managed to sign up over 70 advertisers, who will provide the service with everything from 60-second spots to hour-long infomercials, which will, in the words of TiVo CEO Tom Rogers, "deliver real, relevant results for our advertising partners while at the same time enhancing the TV experience for subscribers." Ads will apparently include gems such as cooking tips for products such as Kraft's Tombstone pizza and Jell-O, and a Ford ad featuring Penn and Teller. As long as we can delete them from our hard drive, we'll live with the ads -- though we may just archive the Kraft spots to DVD; you never know when you'll need some tips on preparing Jell-O or nuking a frozen pizza.
