> The animations look so fake. Let’s talk about why it looks fake. 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 lov…
It looks like 'fake' and animation because it _is_ an animation. The dancing was likely motion captured and/or hand animated and superimposed onto the robots basic balancing control system.
I don't think "basic" is the right word.
