How does it walks? Does it have a hemorrhoids problem? ?

hemorrhoids problem

Human walking type is not optimal - we are always move the mass center up and down during walking.
Asian women are able to walk like this robot, without popping up\down, due to compulsion to carry big load at the head.

So, the robot just keeps a balance.
But women do it much nicer than this robot.

I think that this word summarize everything.
Such things are making big progresses in a very short time.
Apart from this, the result is amazing.

It walks with his knees too much and always bent.
However it is terrifying.

always bent.

sure, damping and balancing. And moreover - the knees cannot be fully straight by design, as i can see on video.

I meant: "always too much bent"

 

[peacemaker]

Just central position to have a possibility to bend + or - during balancing. Noting that higher position is not straight.

I wonder what it's purpose is, other than an expensive toy.

 

[peacemaker]

purpose

At least just a technology that may be sold\licensed to any buyer, like the automotive cars.
Any industrial machine is ... special, invented and shaped only for the specific process.

But human-like worker with palms, fingers, eyes, knees....is universal...

Just imagine the code of this robot firmware....tons of conditions and math...

My observation about this is that: If you look in depth you notice that the speed of walking is about half-speed for humans and the step distance is very short. In order to look more human-like it would have to take longer steps and swing the arms through a longer arc. The main thing, though, that causes that upright way of walking is that the feet do not flex the way that human feet do. When humans walk, there is a heel-ball-toe action to the foot (heel first then the heel rises and the ball of the big toe takes the weight then toe pushes off as the leg moves forward and leaves ground contact). Until they get the robot foot to be flexible in the way that human feet are from the ankle down that gait pattern will persist in robots.

I used to work in a laboratory that did a lot of research on human gait (including head-loading as mentioned by @peacemaker - African women use this method as well) and wrote the software that captured the action of the bottom of the foot on an electric walkway. When these women are observed walking they tend to walk in the same manner as the robot because the foot cannot flex as well with the weight pressing down. The load in the photo is relatively light I have seen women with very big loads of fire wood, with the bundle at least 2 to 2.5 m long and about 500mm to 800mm in diameter.
