This deserves far more attention, This is quite impressive and practical and I can see that these legs could be commercialized soon with a not so big price tag.
That is so cool. Having the calf muscle where a calf muscle would be also means it won't look weird under a pair of jeans. It will be interesting when a User can put one of each leg and walk about.
I’m a disabled veteran, I need that, plus I have ideas for additional design as automation engineer. What if you designed this where you could strap this on the side of your leg, possible just augmenting and supporting a bad knee? It would be great if someday we could strap this type of design to the side of your legs, with strong enough motors/actuators on the axis to support the weight and movement of a normal sized man/woman. We need to abstract this knowledge to the point where someday we’ll be able to build mechatronic suits that will allow disabled humans to strap into to augment rigorous tasks and it has to meet the standard requirements of weight and safety.

Omg, I've been thinking my whole bachelor's degree on using a planetary drive as articularion of a prosthetic limb and now i see it's possible, you guys are awesome
I'm looking around for a planetary gear box of high torque and between 4:1 to 10:1 reduction ration, similar to that you guys are using for your project. May ask where did you get the reducer from?
The able-bodied user demonstrating the device has their own knee joint, so everything gets shifted down. This isn't the case for amputee users, check out our UA-cam channel! That being said, we are working on a new version that makes alignment even better.
hint : you can stick some sensors on a regular leg to collect data, the parameters can be hip and knee angles, orientation ,speed ,acceleration (and maybe neurological signals) , etc then use that data to train a model that can move the leg like a regular human , since humans also train their legs to walk in the first place this was just an idea that can be a total failure in practice

Awesome research! Deserves far more recognition

You and me both brother
At that point why not just have them control it remotely?
It’s almost time boys
would love to see where this is now
Thanks! Browse/subscribe to our channel! We have tons of more recent videos.
Wow those step backs are really awesome
B.A. doing the Lord's work fellas.
Very interesting. Well done guys👍
I know this is 2 years late, but i see no paper link in the description

SDPSI with some modifications, check out the paper in the description
非常好的进展，继续关注
This is super clever!
very cool leg
Does the weight of it light enough for the people who needs it?
🖤 dat goth shoe lift 👀
I love it! 🎉
So why do you have the the prosthetic mounted approximately 4" down from the knee where it would actually be mount to ?
Because the prototype has its own knee. The mount and shoe platform are accomodating for that.

very cool
Would be cool to see it tested by an amputee since they are already used to a prosthetic and see how they adapt to it
Check out our youtube channel, we have plenty of videos with real users!
Amazing
very good Bravo
I'm really surprised you're not working with real amputees
Plus, you guys need all the 💰

Nice, but the real question is: How hard can you kick someone with it?
Fifdy
noice!
now try build GUNDAM
Hanzhen harmonic drive gear , robot joint , over 30 years experience
Looking cool but design is not optimal and needs work.
To much talk and not inuf gundam.
