If I didn't know who Boston Dynamics was, I would have said that this is just CGI. The animations look so fake. I think the issue is that they're aggressively smoothing the motion since mechanical systems don't have the ability to accelerate & jerk as fast as biological systems. Cheap mocap animation has the same problem because the frame rate of the capture system is too low. They interpolate between captured keyfra…
> 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…
On a dancing person you see all the slight adjustments to keep balance that make it feel natural, I believe these robots do it too fast for us to notice and so it seems like CGI where keeping balance isn't a thing.
