Some fun new technology for exoskeletons:

whoa! good post crossroads1946!

amazing . . . blows all the others i've seen out the water (minus the tethered power part)

Yes, I'm pretty sure how it works, I saw this things early stage's in a magazine a while ago, your feet and other body parts are strapped in, and when you move, the exoskeleton simple moves with you, applying extra force when necessary.

probably microswitches contacting the skin, if you move your arm outwards, your arm presses on microswitches inside the suit. Obviously when the suit arm reaches the position your own arm aims for the pressure on the switches will stop. Theres probably a switch at the extent of each joint

but . . . I dont see anything contacting the wearers body except the straps . . .

I suspect that his hands and feet are touching a force feedback device . . . when the hand pushes on it but the arm doesn't move, that means the robot arm should apply force to match it.

That will explain why the arm 'floats' when he isn't using it - because he isn't applying a force to the controls, the arm is therefore stable . . .

the exoskeleton simple moves with you
this is actually a really complicated problem

the other suits I've seen has tried to read your neurons to predict where you are going to move your arm - a very complicated process . . .

this suit however looks . . . so simple!

it does look as if it moves with you just by hand and foot motion only.

i wonder if it works on inverse kinematic principles to determine how the rest of your body is moving

Here's the video with audio - this should clear up a number of points, such as the purpose of the tether and the control mechanism.

Oh yes, I forgot to mention that when I saw the preview of this thing, it was 7 years ago, this backs up my idea that the robot exoskeleton moves with you, because if this company just released a video of this product now, and it still isn't finished, they must have had to spend a very long time making sure there were no flaws in the arms and legs, because if your strapped in, and the robot all of a sudden moves in a way that you can't, it can very easily break and arm or a leg.


P.S. I'm a freshman

hey Tsukubadaisei  leave them alone they are just a couple of kids playing with robotics, they already know cybedyne is better they just want to make a cheap replica,
