I think it comes from the use of hydraulics.
Biological muscle is way less linear (it works more like a second-order control system, where things often overshoot their target before dampening).
But one part of it may also be algorithmic: the robot’s Kalman filter (?) may correct for errors from sensor fusion much faster than a human would.
I would love a more informed opinion than mine though.
Let’s talk about why it looks fake.
