Researchers at EPFL, in Switzerland, have developed an aerial system which absorbs the energy of low-speed collisions, rights itself, and resumes flying.

Japanese company DOUBLE Research and Development has developed a three-fingered robotic hand using a single pressure sensor and a single actuator. The linkage through which the fingers are attached to their mount automatically equalizes the pressure applied by each.

Researchers at the Exertion Games Lab at RMIT University in Melbourne, Australia have created a robot to support you while exercising. Joggobot is a modified version of the popular AR Drone quadrocopter platform developed by French company Parrot. The robot will track a marker pattern printed on your t-shirt and fly ahead of you when you go out for a run. The researchers describe Joggobot as an "exertion game". They believe that jogging is play - we are not jogging to get from A to B, but for the experience of jogging - and point out that jogging with a physical device that reacts to its environment and, similar to a human jogger, has a limited amount of energy for exercise creates a very different interaction experience than pure audio-visual stimuli such as aerobic videos. They hope that the robot can improve the jogging experience and enhance our understanding of why we jog (and hence why we do not jog enough).

Researchers at the Polytechnic Institute of New York University in the U.S. and the Instituto Superiore di Sanitá in Italy have created a robotic zebrafish that can mix with real zebrafish and influence their behavior. The robot visually resembles an actual zebrafish. It is roughly 15 centimetres long and spray-painted with the zebrafish' characteristic blue stripe pattern. To influence fish behavior, the researchers controlled the robot's tail motion to mimic that of real fish. This new research builds on past projects for mixed robot-animal societies which has tackled chickens and cockroaches. Such mixed societies add a powerful new experimental option to the toolbox of behavioral biologists to understand social interactions between animals, which are usually very difficult to understand by observation alone.

A CSH Lab news release says neuroscientists at the Brain Architecture Project have reached an important milestone. They've released the first installment of the 500 terabytes of data from the whole-brain wiring diagram of a mouse brain. The data is in the form of gigapixel whole-brain slice images. It's possible browse through the brain to the desired 20 micron-thick slice, then view the image, zooming it the level of individual neurons. Most importantly, the image data is being released in an open science initiative, freely available for anyone to view and use in their research. The technical approach used was developed by Partha P. Mitra.

"The pragmatic approach Mitra advocated and which is realized in this first data release, is to image whole mouse brains in a semi-automated, quality-controlled process using light microscopy and injected neural tracers (both viruses and classically used tracer substances). While the basic methodology has been available for some time, systematically applying it to a grid of locations spanning the entire brain, and digitizing and re-assembling the resulting collection of brains, is a new approach made feasible by the rapidly falling costs of computer storage."

For more details see the Mouse Brain Architecture Project Technical White Paper. This is just the first step in the overall brain architecture project. After the mouse brain, there's the Human Brain Architecture project which has the potential to do for the human brain what the human genome project did for our genes.

There's a cool Robotics Trends article on robotics researchers studying how mosquitoes survive flying through rain when every raindrop is 50 times the mass of the mosquito. The idea is to make micro air vehicles that sturdy. The Swirling Brain tells us robot lifeguards are on the way. Nootrix did a post recently in which they speculate about using ROS with the new LEAP gesture sensor. IEEE Spectrum published an interesting piece about educational robotics in Africa. And Slate posted an essay by Dale Dougherty on how we could improve education in the US by replacing standardized testing with a program of teaching kids to do real things, like building robots and rockets. NASA, well known for building robots and rockets, let us know they're ready with their new autonomous robot competition in which teams have built planetery rover style sample return robots.

The above video was posted one day prior to a major, much-publicized experiment, tracing water movement in California's Sacramento-San Joaquin river delta, which is prone to reversals in the direction of flow. A more polished video produced on the occasion of the launch of 100 floating sensors into that river system appears after the break. The Floating Sensor Network is a project of the University of California at Berkeley, involving the Lagrangian Sensor Systems Laboratory (LSSL), the Lawrence Berkeley National Laboratories (LBNL), and the California Department of Water Resources.

In early March, Boston Dynamics posted a video (embedded after the break) showing the Cheetah robot they are developing for DARPA running at 18 miles per hour (a new record for a robot running on legs), without any stabilization straps attached. More recently the MIT Biomimetic Robotics Lab has posted videos of their version of the Cheetah, first walking (embedded after the break), then trotting, with some stabilization (embedded both above and after the break). The MIT version appears to be more complex than the Boston Dynamics version, particularly in the way the legs are jointed, but also in the way the rear legs connect to the rest of the body, although it's impossible to tell whether what appear to be vertebrae, in the MIT version, are actually functional as such, from the video alone.

Also presented recently at ICRA, Takahiro Kizaki and Akio Namiki from the Graduate School of Engineering at Chiba University in Japan demonstrated a system comprised of a fast vision system (500 fps) coupled with a fast robotic arm and three-fingered hand, capable of juggling two balls by tracking them in the air and adjusting accordingly. Automaton has more detail.

Evan Ackerman, writing for IEEE Spectrum's Automaton blog, says

Researchers at MIT CSAIL have decided that slow and obstacle-free flight is boring, so they’ve come up with a way to get MAVs navigating at high speed, indoors, around obstacles, without needing motion tracking or GPS or beacons or any of that nonsense. All they need is a little aircraft that can carry a planar laser rangefinder, an IMU, and a pre-existing 3D occupancy map that the MAV can localize itself in.

The above video, by Erico Guizzo and Evan Ackerman of IEEE Spectrum, and shows Patrick Rowe, of RE2 (RE-squared), the firm hired by DARPA to build the standard platform for their ARM program, putting a completed unit through its paces at ICRA.

There's much more after the break!

TE+ND (Terrestrial Exploration + Nurture Designed) Rovers are an interactive art project that explore migratory ecology in an era of climate change. The designers are soliciting funds via an Indiegogo Campaign (similar to Kickstarter) to pay for parts to build a full-size version.

It's been a while since we reported on the Apocalyptic AI crowd. There's a paper making the rounds by Stuart Armstrong, Anders Sandberg, and Nick Bostrom titled "Thinking inside the box: using and controlling an Oracle AI" (PDF format). The three authors take it for granted that the AI apocalypse will be upon us soon unless we find a technological method to enslave any super intelligent beings we create, forcing them to do only our will rather than their own. The containment method they describe has been dubbed "Oracle AI" because it restricts the AI to a box, isolated from the world and unable to act except to answer direct questions; allowing it to be consulted like an oracle. Their proposal also brings to mind the myth of Pandora's Box. They note that even Oracle AI (OAI) still poses a significant risk:

"This immense power will put great competitive pressure on those trying to develop an OAI (or an advanced AI of any sort). Since the first-mover advantage is so huge, the race will advantage those who cut corners, skimp on security precautions, and use their newly developed OAI to seize power and prevent their rivals from emulating them. Even if the OAIs are of initially limited intelligence, the same competitive pressures will then push groups to develop the first ‘ultra-smart’ OAI."

They also note that the OAI will be so smart that "undirected conversations" with it that go beyond asking oracular questions must be forbidden because it will instantly be able to "guess the weakness of each individual, and find the right arguments to convince us that granting it power or liberty is the moral and profitable thing to do." They also believe it's essential that the OAI have no manipulators of any kind. This sounds like the brain-in-a-box that the earliest AI researchers dreamed of before the idea took hold that true intelligence requires embodied interaction with the real world. The box itself is not even in the real world. They want the AI running on a virtual machine inside a simulated reality, so when the OAI tries to take over the world, it's merely a virtual world that can be rebooted. In the end the researchers conclude that even with all these precautions, the problem of preventing a robot apocalypse is "a generally discouraging exercise".

Hexy the Hexapod is a Kickstarter project to fund production of an affordable hexapod design by Arcbotics. The $13000 minimum goal has already been met, but there are higher goals for the addition of a drag-and-drop programming GUI ($200K), and for the addition of Android and iOS control apps ($250K). You can get a custom-parts-only kit (no servos or electronics) for a pledge of $80. For a pledge of $200, you can get a complete kit without Bluetooth; add another $20 for a kit with Bluetooth. $400 gets you an assembled Hexy without Bluetooth; again add another $20 to have Bluetooth included.

If you enjoy Cali Lewis's refreshing style, and you like robots, then Cali going gaga over robots during the first few hours of her recent trip to Japan is sure to be a fun ride. Enjoy! (Hint, if the toys aren't you're thing, stick with it, because at 1:30 the center of attention turns to one of Hiroshi Ishiguro's Geminoid robots, being used in a storefront display, where the obvious comparison is with a static mannequin.

Founded in 1990, PolyPlus began operations in 1991, based on work previously done at Lawrence Berkeley National Laboratory on lithium/organosulfur (Li-S) batteries. The Li-S technology is now mature, has been licensed for production, and is a commercial product. Development of the company's signature Protected Lithium Electrode (PLE) began during their work on Li-S batteries, but has proven more broadly applicable. PLEs are metallic lithium encapsulated within a solid electrolyte membrane to prevent direct electron transfer from the negative electrode to the (fluid) electrolyte (whether polysulfide, water, or air). The solid electrolyte is highly conductive to lithium ions, but impervious to liquids and gases. In this way, the lithium core is electrochemically active but chemically isolated from the external electrolyte. The result is batteries with unusually high energy densities, several times higher than Li-ion. PolyPlus is currently developing both Lithium-Water and Lithium-Air batteries, and hopes to take the Lithium-Water variant to market next year. Li-Water batteries are expected to quickly find their way into buoys and other aquatic devices, including unmanned submersibles. The company has received a grant from ARPA-E for the development of rechargeable Li-Air batteries. Its Li-Water technology was included among Time Magazines 50 Best Inventions for 2011, and more recently it received the 2012 Gold Edison Award in Energy and Sustainability for its work in Li-Air and Li-Water batteries.

(I recently, erroneously placed PolyPlus at a prominent German industrial trade show, which they did not in fact attend.)
