Wow Amby another great link ... very interesting idea..

I saw this LINK to get more information about it 

Then the first picture I see is this

HEY .. ITS PRINTABLE .. OPEN SOURCE !! .. Then reading a little more I see "patent pending" ... So this was probably a development model for the company .. which was printed...

Interesting idea..

PROs - can probably move a large force, a short distance, at high speed .. which our leg muscles do .. considering they are attached with tendons very close to the joints .. 
Leg muscles move huge force, quickly, but they really contract a short amount.

Over all the design seems fairly simple...

CONs - 2 motors? Why? ... Fabricated metal torque wench gear..  Biggest drawback - "patent pending"

 

Ok saw some videos .. these guys seem young and aware of the "maker" culture ..  After seeing this video, to me it seems this might be one of InMoov's "real" possiblities of realistic "walking"

Gael should ask for some .. they'd probably give him several units...

If you look at the video you can see examples of the torque and speed.

 

 

Yes I think it has potential.  The part I'm concerned about is the "patent pending". So I don't think there is a stl online.  Someone could contact them and offer to demonstrate functionality in exchange for a few of their units, but I would prefer using open source solutions.

Curious to see if so simple a design is patentable - clever as it  is.  I mean the core of the design goes back to a conical windlass .. which is pretty ancient :D

 

These guys are going to be at the table next to me with the InMoov at the MIT Mini Maker,  I'll definitely have a chat with them and see what they're up to.  Maybe get some demo units if I'm lucky...
