The motion, form-factor and the range of movements is certainly good, but looking at some of the other videos[1] shows the arm really is the neat, tiny protuberance of much larger stack of technology. The pumps and everything else appear massive and bulky. Biological muscles are self-contained, not tethered. This is no doubt an impressive demonstration of integration, but unless all those pumps are inside the arm, the further claims about how this technology will be used seem a bit ... stretched.

- micromacrofoot 5y agoThese things always start off large and gradually get smaller (and often miniaturization is where the really interesting optimizations come), apparently this apparatus can already fit roughly within a human-sized body... which isn't a bad start.
- fho 5y agoWhile this definitely is an impressive an impressive one, those artificial pneumatic muscles have been around for ages [1] but have not become much smaller. My guess would be that there is some physical limit on how useful they can be.

- micromacrofoot 5y agoPhysics certainly makes fools of us all.
- Robotbeat 5y agoPutting the pumps in the torso is a good idea. Putting them inside the arm itself increases the inertia of the arm.
- kobalsky 5y agoyou don’t have an eureka moment and build a perfectly functional android from scratch. this is a necessary step towards a better-than-human arm
