Finally, Robots That Turn Into Furniture


Get ready for self-constructing, shape shifting, moving-on-command furniture — or as its creator like to call it, Roombots.

There are a lot of things we imagine our future robot overlords doing. But making, or rather being our furniture is probably not one of them. The kind of robot furnishings researchers at Switzerland-based technical university Ecole Polytechnique Federerale de Lausanne (EPFL) are working on is the stuff of dreams (and maybe a few nightmares).

Roombots are actually robotic modules, roughly 6x6x6 inches and weighing about 3 pounds, that include a few motors for three degrees of movements. They can roll slowly on the ground or use their built-in grip modules to attach themselves to each other or objects like specially-designed table-tops.

According to scientist Auke Ijspeert of the EPFL’s Biorobotics Laboratory in Switzerland, Roombots can build themselves into adaptive furniture that can change from a chair to, say, a table and even rise up to meet you. This second feature could be especially important, as one of Ijspeert’s goals is to make Roombots an assistive technology. A Roombot table could, for example, twist its legs so it becomes taller and easier to use for someone who has trouble bending down to reach the table top. Alternatively, a Roombot chair could move into place and rise up to help someone sit, instead of that person having to flop down into a tech-free chair.



The robot modules, which communicate via Bluetooth and run for an hour on a charge, can grab each other and, potentially join up in groups to turn a robot chair into a bigger robot bench. They also connect with passive modules, like a tabletop piece or anything else, like a lamp, container or camera, as long as these pieces have special notches to accept the Roombot’s powered grippers. Those same grippers also allow the modules to climb special walls. So, for example, a collection of them could line the walls of a seemingly empty meeting room and just the right number could climb down and combine into a set of self-aware conference table and chairs.

While the video is compelling, researchers have a lot of work do before we see robots tuning into furniture and rushing to offer themselves as a seat. EPFL reports that engineers hope to make the Roombots more practical by speeding up their movements and acknowledge that there’s still much work to be done on the configuration algorithms. Scientists told that industrial use is 15 years away and it could be two decades before they could be used reliably by every day consumers.

FDA Approves Segway Inventor's Mind-Controlled Robotic Arm




The era of real cyborgs has begun. The U.S. Food and Drug Administration (FDA) gave its first approval for the sale and marketing of a prosthetic arm that translates signals from a person’s muscles on Friday.

Informally known as the "Luke" arm (a reference to Luke Skywalker's robotic arm in Star Wars), the Deka Arm, which is controlled by electrical signals from electromyogram (EMG) electrodes connected to the wearer's muscles, can now move from research experiment to full-fledged commercial product. That's right, bionic limbs are about to go mainstream

" The Deka Arm System may allow some people to perform more complex tasks than they can with current prostheses in a way that more closely resembles the natural motion of the arm," said Christy Foreman, the director of the Office of Device Evaluation at the FDA's Center for Devices and Radiological Health in a statement.

In a demonstration video (see above) released on Friday, Fred Downs, one of the recipients of the Deka Arm, is shown using the prosthetic hand to delicately pick up and move a carton of eggs. Like the device's nickname, the demonstration is indeed reminiscent of the dexterity exhibited by Luke Skywalker's robotic hand, a technology that was pure science fiction just a few decades ago, when the movie was first released.

The Deka Arm's electrodes, which are attached to the muscles of the wearer, transmit signals to a processor in the prosthesis, which then interprets those signals and turns them into up to 10 distinct movements.



In yet another video (see above), Downs is shown using the Deka Arm to open up a piece of mail, a seemingly simple demonstration that is nevertheless indicative of the device's precision.

And while the project was sponsored by the Defense Advanced Research Projects Agency (DARPA) and the U.S. Army Research Office, Dean Kamen, the inventor of the Segway, and his team at Deka Research were instrumental in its development, hence the name.

Micro Magnet Robots Can Build Mini Super Structures


Magnets and their properties have long fascinated everyone from children to scientists, but it's unlikely you’ve ever seen them harnessed quite like this.

SRI International, a non-profit research firm serving government and industry, has found a novel way to control tiny, low cost magnets via electromagnetic pulses delivered to them through contact with printed circuit boards.

The patented process, known as Diamagnetic Micro Manipulation (DM3), can move magnetically actuated micro-robots at speeds of up to 3 CM per second, in any direction and even along curved circuit boards. As long as there’s an electromagnetic current running through the circuitry, the magnets will hold on and do your bidding. The system can host not just one magnet on a board, but dozens, which can work together or perform separate task. All the instruction comes through the electromagnetic pulses in the board.

Making one or even dozens of little magnets move and almost dance in unison is entertaining, but it's when SRI started adding what it calls "effectors" to the magnets that things got really interesting. "Effectors" are basically little pieces of wires or other add-ons that allow the magnets to pick up, hold and manipulate materials.

In the video above, the magnets are programmed to grab, move and glue carbon-fiber sticks. Eventually, they built a 29-centimeter-long truss capable of supporting up to 2 kg.

According to SRI, which is working on the project with DARPA, "Our vision is to enable an assembly head containing thousands of micro-robots to manufacture high-quality macro-scale products while providing millimeter-scale structural control."

The company believes these micro robots could someday power entire micro factories.

The video, by the way, looks pretty mundane until you realize it’s garden variety magnets acting as if they’re alive and capable of working as hard as you’re everyday construction worker.

Bionic Kangaroo Hops Into the Future of Robotics


Finally, a robot that successfully imitates a living thing without making you think of human extinction scenarios from The Terminator.

Germany-based Festo has unveiled its latest creation, the Bionic Kangaroo, a hopping robot fashioned in the image of a real kangaroo.

Weighing just over 15 pounds and standing 39 inches tall, the robot has the ability to jump forward at lengths of about two-and-a-half feet and has a vertical leap of a about one-and-a-half feet.

With an outer shell designed to mimic the form of a kangaroo, from its tiny front paws down to its curved tail, the robot jumps using pneumatic springs working in conjunction with sensors in its heels and main body. When it lands, it uses the recovered energy stored during leaps for its next jump.

The Bionic Kangaroo has two motors for the hips, one motor for the tail and, instead of a pouch, the robot's stomach area contains a pressure accumulator.

The robot's movements can be controlled through a user's wireless armband. Using various arm motions, the wearer can direct the Bionic Kangaroo to hop forward or turn in small circles to change its direction.

Although the company has not offered any specific uses or commercial release details for the robot at present, the Bionic Kangaroo represents its latest successful attempt to robotically mimic the look and locomotion of a living creature.

This time last year, the company took the wraps off a flying robot called the BionicOpter, a tiny drone with the appearance and hovering movements of a real dragonfly.

What Google Is Really Doing With All Those Robot Companies


Since December of last year, Google has purchased at least six companies either buildings robots or creating technologies used in the development of robotics.

Former Google Android lead and current Google Robot Guru Andy Rubin's list of acquired companies reads a bit like a baseline robot kit:

> Redwood Robotics for robot arms

> Holomni for robot wheels

> Bot & Dolly for robotics cameras

> Boston Dynamics for creepy and cool mobile robots

> DeepMind Technologies for artificial intelligence

> Meka Robotics for humanoid robots

> Industrial Perception for computer vision (which may or may not be for robotics)

While we know Google has interest in self-driving cars, the robot end-game is unclear. Sure, you can build an army of C-3POs, but for what?

Well, robots are excellent at repetitive tasks, like changing the settings on millions of computers so that they have Google.com as their home page and Google as their default search engine. Would these Google Robots invade homes to make the change or would Google offer it as a service? Send us your computer and our robots will "fix" them.
