We’ve covered a ton of Boston Dynamics robots but this is the second one in a row that has shown a departure from what a lot of people’s notion of an ‘advanced’ robot should look like. It’s a cellphone camera clip of a video played at a conference, but at least it isn’t vertical video — kudos to [juvertson]. At about 3:40 seconds into the video you get a good look “Handle” at a four-limbed robot with backwards joints and wheel.
This design makes a lot of sense and it’s good to see Boston Dynamics thinking about unique robot kinematics alongside the realities of motion. The result is something that appears neither human nor animal — it’s definitely not natural. Despite the presenter’s assertion that this will be nightmare-inducing, we think it’s the opposite, since it doesn’t tweak that string in your brain that cries “predator”.
Obviously this is what we’d call a self-balancer. But two-wheels-plus-rigid-frame it is not. The articulated lower limbs allow it to shift its mass over the wheels. The upper limbs play their part in balancing, at one point acting in the same way a figure skater’s arms would during a spin. And its dexterity in hopping over an obstacle is only made better by [juvertson’s] commentary. This is a really good balance between purely wheeled and purely humanoid designs and a nice addition to the evolution of robotics.
Boston Dynamics, we’re huge fans of your work here at Hackaday. We’d love to stop by for a tour to interview your engineers and talk all things about the future of robotics. Let us know if this is a possibility!

There’s nothing particularly odd about knees that face backwards. Sure, the average horse or tapir doesn’t have wheels to move around, but many four-legged herbivores have knees that face backwards. If anything, this robot looks like a bucking horse on wheels.
Still pretty cool, though.
In fact, a great number of mammals use their heel as a “backwards knee”.
Digitigrade or walking on the tips of their toes, or what would be such for animals with hooves. Primates are Plantigrade with the heels on the ground when standing..
That is how every bird is built.
Disagree. It’s still creepy. Most of these robots are technically very interesting but the uncanny valley effect is still pretty extreme here. It is definitely tweaking some strings here though it is unclear if any contemporary movies have touched on this specific type of robot motion or physical arrangement?
For me, the creepiest part is more the lack of organic movement, rather than the form. As far as form goes, I just see an odd-toed ungulate. The wheels that negate the need for walking legs, plus the speed at which movement stops and starts, is a different matter. But that applies to all robots.
I’m pretty sure they are not backwards, it’s just rolling in reverse.
Birds, as well, have backward facing knees.
Nope, those are actually analogous to a heel. Chicken legs are actually the shins, between knee and heel. Chicken thighs are the thighs, between hip and knee joints. Look up Digitigrade and Plantigrade.
The birds’ femurs are normally hidden within their feathers. This makes it easy enough to make that mistake.
tachikoma is that you?
this does remind me of the wheeled leg locomotion of the gits universe.
I’d say RideBack is probably an even closer match.
yup probably many others i havent seen as well.
Hmm, well, with the wheels on the legs I can sort of see a resemblance…..
Though with the smaller limbs in front I found myself thinking of that robot from the Lost in Space movie.
Cool video. Reminds me of a yinglet.
Mildly disturbing, but definitely impressive.
Don’t know if it’s backwards. Looks just a bird’s, dog’s, or horse’s “ankle”.
Just before filming, Robot to Engineer: “Here, hold my oil can…”
That would make one badass mobility scooter.
The way tech is exploding right now you won’t need mobility scooters, We will all have robot’s that go shopping for us along with our drone drop off systems like the one’s Amazon seem to be building and trying to corner the market with.
so that scene from robocop…
almost as stopmotion as the one in robocop
Toward the end of the clip when it jumps you can see a part go flying off. It looks like a bumper, or rubber cap or something.
If a studio wanted to do a “Fahrenheit 451” movie with a real robot hound to chase Guy Montag, Boston Dynamics would be the company to build it.
Boston Dynamics has a long history of not caring about uncanny valley. Their Big Dog has forelegs that pivot like knees, but hind legs that pivot backward. This probably makes it work just as well walking either direction, but it certainly triggers my uncanny valley revulsion.
I don’t get it why they named it big dog. It’s more like a donkey in both appearence and purpose of use.
BigAss would have gotten far more press.
Since the gas powered version was too noisy for the military, the headlines practically write themselves.
now it needs a set of arms so it can do work. its speed and agility are kind of scary but amazing
I half expected Motoko Kusanagi to step out of the back of this thing at the end, therem
Does Boston Dynamics remind anyone else of Massive Dynamic from Fringe?
They need to find a way to allow people to view videos of the event from home, some kind of way to connect computers together with a service to host the videos. Then you don’t have to have EVERYONE holding their phones up to video it.
Hello!I really love how this site is laid out and how it’s organized. I was wondering if it was possible if someone could be able to help me add author’s profiles to my website. One thing that really stood out to me is that you were able to click on the author’s name of this article and it brings up their own profile page linking all their articles with more information. I am working on a site for my class and would be in my best interest to add this feature to my own. How would I be able to do this?
