It looks like the difference between the Boston Dynamics robots 2016 vs 2021

The Spot dog (which inspired the Black Mirror "Metalhead" episode) in 2016 https://www.youtube.com/watch?v=tf7IEVTDjng

Atlas doing backflips in 2021 https://www.youtube.com/watch?v=FByY3tSx2Ak

So 5 years of progress within a year.

spot dog is hydraulically powered junk, unitree is motor driven from day one. Boston Dynamics was forced to switch to a motor driven architecture after it is proven by unitree.

Boston Dynamics is the follower here.

I look after one at a University that gets used for teaching & outreach & there's definitely no hydraulics on the thing.
