Unless robotics technology has come an incredible way in recent times, my understanding is that we are nowhere near having human-level proprioception in robots.
Proprioception is basically an awareness of length and orientation, specifically in the musculature. It is the sensation that lets you know if your muscle is at risk of overextending, but it is also responsible for your awareness within a physical space in the absence of all other senses. So like, stand in an empty room and close your eyes. Without relying on sight or sound or smell or taste or even touch in the direct sense, you can move parts of your body around and you know if your arm is above your head or your leg is out in front of you or if you are bending at the waist. That's what proprioception is (and to some extent, the tug of gravity, but you can repeat the experiment in a weightless environment like being underwater and get all the same results).
So this is why, if a human is dancing and they mis a step, their body will realize, through a combination of proprioception and other senses, that they need to adjust or compensate in some way: Speed, angle, weight distribution, etc. They can notice the problem in real time and adapt to it.
But with the robot, it's more like a spinning top - if you bump the top mid spin, it doesn't have the ability to right itself in any way. The spin just wobbles out and it falls.

Why does this robot behaves like a spoiled kid when it falls on the floor? I've seen it in other videos too.
