Most aquatic animals propel themselves with a tail or fluke, so roboticists have long been interested in the remarkable speeds possible by mimicking sea lion propulsion with front flippers. Read the rest
Yale engineers developed "robotic skins" from elastic sheets integrating sensors and electromechanical actuators. The idea is that most any flexible object could be transformed into a robot. Professor Rebecca Kramer-Bottiglio and her colleagues reported on their project, called OmniSkins, in the journal Science Robotics. From YaleNews:

Placed on a deformable object — a stuffed animal or a foam tube, for instance — the skins animate these objects from their surfaces. The makeshift robots can perform different tasks depending on the properties of the soft objects and how the skins are applied.
“We can take the skins and wrap them around one object to perform a task — locomotion, for example — and then take them off and put them on a different object to perform a different task, such as grasping and moving an object,” she said. “We can then take those same skins off that object and put them on a shirt to make an active wearable device.”
I woke up this morning to the sad news that maker-pal and pioneering hobby roboticist, Gordon McComb, had passed away. I wrote a brief eulogy on Make:

It is with a heavy heart that we here at Make: announce the passing of hobby robotics pioneer, Gordon McComb. He died on Monday, Sept 10th, apparently of a heart attack. Gordon was a great friend to Make: and to makers and robotics hobbyists from around the world.
Gordon’s Robot Builder’s Bonanza book, first published in 1987, arguably marks the beginning of hobby robotics as a significant maker category. It was the book that I bought in the late 80s that got me into robot building, and by extension, all forms of hardware hacking...
Gordon was an encyclopedist, a collector of useful information and ideas. His Robot Builder’s Sourcebook, an outsized, sort of Whole Earth Catalog for robot builders, was an absolute treasure trove of access to most every tool and component available at the time (2002). Most recently, Gordon created the book and kit, How to Make a Robot, for Make:.
Fellow hobby robotics pioneer, Mark Tilden, once said: “A human is a way that a robot builds a better robot.” Few humans have done more to build better robots and advance robotkind than Gordon McComb.
Godspeed, Gordon. Your numerous friends and fans, both organic and mechanic, will miss you very much.
When fire ants dig out a new nest underground, a small number are actually doing most of the work while the rest dilly-dally. Apparently this is actually an effective division of labor because it prevents the insects from getting in each other's way. Now, Georgia Tech researchers suggest this approach could be help future robot swarms be more efficient in cramped areas like collapsed buildings or construction sites. From Science News:
(Physicist Daniel) Goldman’s team created computer simulations of two ant colonies digging tunnels. In one, the virtual ants mimicked the real insects’ unequal work split; in the other, all the ants pitched in equally. The colony with fewer heavy lifters was better at keeping tunnel traffic moving; in three hours, that colony dug a tunnel that was about three times longer than the group of ants that all did their fair share.
Goldman’s team then tested the fire ants’ teamwork strategy on autonomous robots. These robots trundled back and forth along a narrow track, scooping up plastic balls at one end and dumping them at the other. Programming the robots to do equal work is “not so bad when you have two or three,” Goldman says, “but when you get four in that little narrow tunnel, forget about it.” The four-bot fleet tended to get stuck in pileups. Programming the robots to share the workload unequally helped avoid these smashups and move material 35 percent faster, the researchers found.
Limited to two motors and $600, mechanical engineering students from the University of California, Davis designed and built this shoe-tying machine. I particularly appreciate how the robot uses the same technique as I do: the bunny ears method.
Rolls Royce and Harvard University are exploring how tiny swarm robots could someday crawl through an airplane engine for mechanical check-ups and maintenance.
Each robot measures around 10mm in diameter which would be deposited in the centre of an engine via a ‘snake’ robot and would then perform a visual inspection of hard to reach areas by crawling through the engine. These robots would carry small cameras that provide a live video feed back to the operator allowing them to complete a rapid visual inspection of the engine without having to remove it from the aircraft.
Tokyo grad student Tezuka Sota's "Origami Hand" is a robotic gripping hand whose plastic-coated, water-resistant folded paper is sterile, disposable, and free from moving parts and lubricants, meaning it can be used in difficult environments that are hostile to bearings and oils, like space or underwater.

For 25 years, my friend Kal Spelletich of Seemen and Survival Research Labs has lived and worked in a San Francisco warehouse studio where he's built myriad robots, fire machines, and sculptures, hosted music, art, and political action events, and provided support for more than 100 other artists, activists, and fringe characters. Guess what. Kal's been evicted. This is yet another gut punch for the Bay Area's creative community that inspired so many technologists but is now being eviscerated by today's big money tech bubble. Kal has launched a GoFundMe campaign to help him push through: Save Kal's Robots

Rented way back in 1995, my space is was one of the last remaining raw warehouse art spaces and I made it into a home for experimental, non commercial art. I hosted jaw-dropping, fire spewing, ear shattering robot performances, music, noise and art events with the likes of Chris Johanson, Johanna Jackson, Marie Lornez and her epic boat, the Sisters of Perpetual Indulgence, Matt Heckert.
I did all this without grants or outside support.
No trust funds, patrons or high paying side jobs here. I passed along the cheap rent.
I provided housing and studios for countless artists, freaks, traveling activists and radical journalists like Trevor Paglen, AC Thompson, Heather Dewey-Hagborg, worked on Survival Research Laboratories shows, and countless others.
My life and warehouse were the inspiration for Rudy Rucker’s sci-fi novel Realware. Another book that wouldn't have happened without my warehouse is Streetopia.
I ran my studio as an experimental art/live space that housed and supported over 100 other artists and activists.
This is the Dual-rotor embedded multilink Robot with the Ability of multi-deGree-of-freedom aerial transformatiON, aka DRAGON. Designed at the University of Tokyo, this modular bot can rearrange its shape, from an agile snake to a spiral to a flying "L" shape. From IEEE Spectrum:
What’s exciting, though, is why this robot was designed to transform in the first place. The video, which—spoiler alert—is actually a teaser for a 2018 IROS paper, shows the robot changing its shape in order to squeeze through a small gap, and we were told at ICRA that DRAGON is able to autonomously decide how to transform when given the constraints of the space it needs to pass through. There’s more potential here than just fitting through small spaces, though: The researchers conceptualize this robot as a sort of overactuated flying arm that can both form new shapes and use those shapes to interact with the world around it by manipulating objects. Eventually, DRAGON will wiggle through the air with as many as 12 interlinked modules, and it’ll use its two ends to pick up objects like a two-fingered gripper. And we can imagine DRAGON wrapping itself around stuff to move it, or using direct contact with the environment to do other exciting things.
MIT researchers designed and 3D-printed an array of soft, mechanical critters that are controlled by waving a magnet over them. The shapeshifters that fold up, crawl, grab things, and snap together into intricate formations may someday lead to new kinds of biomedical devices. For example, one of the devices "can even be directed to wrap itself around a small pill and carry it across a table." From MIT News:

“We think in biomedicine this technique will find promising applications,” says (MIT mechanical engineer Xuanhe Zhao.) “For example, we could put a structure around a blood vessel to control the pumping of blood, or use a magnet to guide a device through the GI tract to take images, extract tissue samples, clear a blockage, or deliver certain drugs to a specific location. You can design, simulate, and then just print to achieve various functions.”
In addition to a rippling ring, a self-squeezing tube, and a spider-like grabber, the team printed other complex structures, such as a set of “auxetic” structures that rapidly shrink or expand along two directions. Zhao and his colleagues also printed a ring embedded with electrical circuits and red and green LED lights. Depending on the orientation of an external magnetic field, the ring deforms to light up either red or green, in a programmed manner.
Five years ago, my artist/engineer pal Kal Spelletich drew at crowd at an Institute for the Future conference by demonstrating his "Huggerer," a pneumatic robot that delivers free hugs. Now robot hugs are the subject of new scientific research! At a recent human-robot interaction conference, researchers from Stuttgart, Germany's Max Planck Institute for Intelligent Systems presented their efforts to explore "how robots can be more effectively designed and taught to give the kinds of hugs that humans will love." From Evan Ackerman's fascinating interview with lead researcher Alexis Block in IEEE Spectrum:

IEEE Spectrum: Why is research on robot hugs important?
Alexis Block: Robot hugs are important because people love to give and receive hugs. Virginia Satir, a well-known family therapist, was famous for saying, “We need four hugs a day for survival. We need eight hugs a day for maintenance. We need 12 hugs a day for growth.” Sometimes, we are put in new or uncomfortable situations where we might not be near our loved ones, but that doesn’t mean we don’t need the support and calming effects that a hug provides. Research on robot hugs is important so we can one day use technology to provide the emotional support and health benefits of hugs to many people, wherever or whenever they need it.
What makes a good hug?
The results from our experiment suggest that to make a good hug whoever/whatever you hug should be compliant, warm, squeeze you, and release you immediately when you indicate you’re ready for the hug to end.
This "biohybrid" robotic finger melds a robotic skeleton with living rat muscle. The device is inside a container of water to keep the muscles from withering. The research is on the cover of this week's issue of the journal Science Robotics. Video below. From National Geographic:
“If we can combine more of these muscles into a single device, we should be able to reproduce the complex muscular interplay that allows hands, arms, and other parts of the body to function,” says study author Shoji Takeuchi, a mechanical engineer at the University of Tokyo. “Although this is just a preliminary result, our approach might be a great step toward the construction of a more complex biohybrid system.”
The research group began looking at living muscle tissue because plastic and metal provided a limited range of movement and flexibility. To grow their robot's muscles, they layered hydrogel sheets filled with myoblasts—rat muscle cells—on a robotic skeleton. The grown muscle is then stimulated with an electric current that forces it to contract.

“Imagine shifting some of infrastructure services that usually take place during the day on the road — deliveries, garbage management, waste management — to the middle of the night, on the water, using a fleet of autonomous boats,” says (MIT Computer Science and Artificial Intelligence Laboratory) director Daniela Rus, co-author on a paper describing the technology that’s being presented at this week’s IEEE International Conference on Robotics and Automation.
Moreover, the boats — rectangular 4-by-2-meter hulls equipped with sensors, microcontrollers, GPS modules, and other hardware — could be programmed to self-assemble into floating bridges, concert stages, platforms for food markets, and other structures in a matter of hours. “Again, some of the activities that are usually taking place on land, and that cause disturbance in how the city moves, can be done on a temporary basis on the water,” says Rus, who is the Andrew and Erna Viterbi Professor of Electrical Engineering and Computer Science.
The boats could also be equipped with environmental sensors to monitor a city’s waters and gain insight into urban and human health.
When Sony announced in 2014 that support was ending for Aibo, their pioneering line of robotic dogs, former Sony employee Nobuyuki Norimatsu launched A-Fun, a repair service in Japan, to take care of any ailing Aibos. Things progressed from there. Video below. From National Geographic:
Norimatsu came to regard the broken AIBOs his company received as “organ donors.” Out of respect for the owners’ emotional connection to the “deceased” devices, Norimatsu and his colleagues decided to hold funerals.
A-Fun approached Bungen Oi, head priest of Kōfuku-ji, a Buddhist temple in Chiba Prefecture's city of Isumi. Oi agreed to take on the duty of honoring the sacrifice of donor AIBOs before their disassembly. In 2015, the centuries-old temple held its first robot funeral for 17 decommissioned AIBOs. Just as with the repairs, demand for funeral ceremonies quickly grew...
According to Head Priest Oi, honoring inanimate objects is consistent with Buddhist thought. Nippon.com quotes the priest: “Even though AIBO is a machine and doesn’t have feelings, it acts as a mirror for human emotions.”
This is "Stickman," a robot acrobat that Disney Research scientists presented at this week's IEEE International Conference on Robotics and Automation. From the abstract of their technical paper:
Human performers have developed impressive acrobatic techniques over thousands of years of practicing the gymnastic arts. At the same time, robots have started to become more mobile and autonomous and can begin to imitate these stunts in dramatic and informative ways. We present a simple two degree of freedom robot that uses a gravity-driven pendulum launch and produces a variety of somersaulting stunts. The robot uses an IMU and a laser range-finder to estimate its state mid-flight and actuates to change its motion both on and off the pendulum.
Husqvarna bills its machines as "remote workmates ready to tackle your heaviest, most challenging jobs."
Compare that to what Survival Research Laboratories founder Mark Pauline told me in a 1993 interview:
"The real message of machines isn't that they're helpful workmates," Pauline said. "Like any extension of the human psyche, machines are scary things," he says. When you take the scary human psyche and magnify it hundreds or thousands of times with technology, it's really nightmarish."
