We value position control more than force control (i.e., controlling motors for force output used to be very popular, but nowadays controlling for position is in vogue, so to speak, although force and position are obviously related), but th

Not quite... From the article - "The testing I signed up for is needed to win U.S. Food and Drug Administration approval." Powered exoskeletons for spinal cord injury or paralysis patients are medical devices, and thus require FDA

You can read a news release from MIT about such an endeavor here: http://news.mit.edu/2015/bipedal-robot-with-human-reflexes-0... The limiting factor remains not the human, so much as the hardware and software design b

I agree with the essence of your argument (and congratulations on the training). I do, however, fear i might've brushed over the essential idea - rather than provide training, wearable's should provide constant 'feedback&#x27

Not quite - the technology and approach taken are essentially very new developments in the field, in general to avoid pitfalls of current/past state of the art. Since exoskeletons should be useful to humans, they should probably be des

An interesting thing to note WRT serious applications for exoskeletons is that they arguably offer greater potential as safety devices in the workplaces, essentially as a means to stop workers from over straining themselves, and also preven

Have you used a consultancy based group to help with the documentation/app.? Doing a 510k w.o that experience/perspective seems insane (especially for a startup(?)). Also, I'm not sure which field you are in, but I've ge

This is a textbook, ZMP derivative type controller. ZMP doesn't necessarily require absolute maps of the environment, but generally is more of a predict and optimize for safety type affair, and Atlas i'd imagine does that both ver

Great question. Disclaimer: I don't work with these types of bipeds. I work on powered exoskeletons for paralyzed type people. I would google that phrase to get an idea, but what you'll find is not close to what i'm working o

Short answer: No, ZMP is still the name of the game +-. [0] Slightly longer answer: No, they use derivative approaches that are basically ZMP but generally more refined/modernized, which is not to say ZMP/related are good or the &
