Legged robots from Boston Dynamics can navigate a home, and even deliver a parcel, using advances in manipulation and vision.
Will Knight writes: The nimble-legged robots under development at a secretive Google subsidiary are getting ever more capable and clever.
At a conference in Barcelona this week, Marc Raibert, the CEO of Boston Dynamics, which specializes in dynamically balancing legged machines, demonstrated some of the progress his researchers have been making.
“Many people are talking about drone delivery. So why not just plain legged robots?”
— Marc Raibert, the CEO of Boston Dynamics
Raibert demonstrated Spot Mini, the company’s latest four-legged robot, which is about the size of a large dog. Boston Dynamics has previously shown videos of Spot Mini operating in a mocked-up home—climbing stairs, opening doors, and even emptying a dishwasher using its gripper. The robot features a neck-like appendage and gripper that enables it to do simple, but potentially useful, manipulation tasks.
The robot is partially automated. A Boston Dynamics engineer steered a Spot Mini onto the stage during Raibert’s talk at the Neural Information Processing Systems conference. But the robot figured out for itself how to perceive and navigate the steps up to the stage, and then, once given the command, located and picked up a can from a table.
Legged robots could potentially be better than wheeled bots at navigating messy human environments, although the research robots under development at Boston Dynamics remain prohibitively expensive for now, some costing more than $1 million.
Boston Dynamics has built a reputation for developing robots capable of walking and running, even across treacherous ground using dynamic balance; that is, by constantly moving to maintain stability. The company has honed the technique over many decades to produce several stunning machines (see “The Robots Running This Way”). It makes a much larger quadruped, called Big Dog, which has been tested as a military pack mule, as well as a humanoid, Atlas, which took part in a robot rescue contest organized recently by the Defense Advanced Projects Research Agency (see “Why Robots and Humans Struggled with DARPA’s Challenge”).
As Boston Dynamics explores potential applications, it’s clear that manipulating objects while balancing this way will be a key focus. “Mobile manipulation is our next grand challenge,” Raibert said during his talk. Read the rest of this entry »
Devin Coldewey reports: Robots have been a major focus in the technology world for decades and decades, but they and basic science, and for that matter everyday life, have largely been non-overlapping magisteria. That’s changed over the last few years, as robotics and every other field have come to inform and improve each other, and robots have begun to infiltrate and affect our lives in countless ways. So the only surprise in the news that the prestigious journal group Science has established a discrete Robotics imprint is that they didn’t do it earlier.
In a mere 50 years, robots have gone from being a topic of science fiction to becoming an integral part of modern society. They now are ubiquitous on factory floors, build complex deep-sea installations, explore icy worlds beyond the reach of humans, and assist in precision surgeries… Read the rest of this entry »

A panel of experts discusses the prospect of machines capable of autonomous reasoning
Ted Greenwald writes: After decades as a sci-fi staple, artificial intelligence has leapt into the mainstream. Between Apple ’s Siri and Amazon ’s Alexa, IBM ’s Watson and Google Brain, machines that understand the world and respond productively suddenly seem imminent.
The combination of immense Internet-connected networks and machine-learning algorithms has yielded dramatic advances in machines’ ability to understand spoken and visual communications, capabilities that fall under the heading “narrow” artificial intelligence. Can machines capable of autonomous reasoning—so-called general AI—be far behind? And at that point, what’s to keep them from improving themselves until they have no need for humanity?
The prospect has unleashed a wave of anxiety. “I think the development of full artificial intelligence could spell the end of the human race,” astrophysicist Stephen Hawking told the BBC. Tesla founder Elon Musk called AI “our biggest existential threat.” Former Microsoft Chief Executive Bill Gates has voiced his agreement.
How realistic are such concerns? And how urgent? We assembled a panel of experts from industry, research and policy-making to consider the dangers—if any—that lie ahead. Read the rest of this entry »
Boston Dynamics’ four-legged robot named WildCat can gallop at high speeds
Google confirmed on Friday that it had completed the acquisition of Boston Dynamics, an engineering company that has designed mobile research robots for the Pentagon. The company, based in Waltham, Mass., has gained an international reputation for machines that walk with an uncanny sense of balance and even — cheetahlike — run faster than the fastest humans.
It is the eighth robotics company that Google has acquired in the last half-year. Executives at the Internet giant are circumspect about what exactly they plan to do with their robot collection. But Boston Dynamics and its animal kingdom-themed machines bring significant cachet to Google’s robotic efforts, which are being led by Andy Rubin, the Google executive who spearheaded the development of Android, the world’s most widely used smartphone software.
The deal is also the clearest indication yet that Google is intent on building a new class of autonomous systems that might do anything from warehouse work to package delivery and even elder care.
In an interesting twist, Valkyrie seems to be a girl. While officially genderless, “Valkyrie” (a nickname, since the official designation is R5) evokes the goddess-like females of Norse myth.
Its Iron Man-style glowing chest ring nestles in a pronounced bosom that contains linear actuators for waist rotation.
“We really wanted to design the appearance of this robot to be one that when you saw it (you’d say) ‘Wow. That’s awesome,'” Nicolaus Radford of the NASA JSC Dextrous Robotics Lab says in the video below by IEEE Spectrum.
John Biggs writes: Welcome to our continuing series featuring videos of robots that will, when they become autonomous, hunt us down and force us to work in the graphene factories of Mars. Below we see Wild Cat, a fully untethered remote control quadrupedal robot made by Boston Dynamics, creators of the famous Big Dog. This quadruped can run up to 16 miles an hour and features a scary-sound internal gas engine that can power it across rough terrain. Wild Cat was funded by the DARPA’s M3 program aimed at introducing flexible, usable robots into natural environments AKA introducing robotic pack animals for ground troops and build flocking, heavily armed robots that can wipe out a battlefield without putting humans in jeopardy.
Next up we have ATLAS, another Boston Dynamics bot that can walk upright on rocks. Sadly ATLAS is tethered to a power source but he has perfect balance and can survive side and front hits from heavy weights – a plus if you’re built to be the shock troops of a new droid army. ATLAS can even balance on one foot while being smacked with wrecking balls, something the average human can’t do without suffering internal damage. I can’t wait for him to be able to throw cinder blocks!
