To best understand the speed of progress right now, take a look at the show from last year: https://www.youtube.com/watch?v=JIq_AM4q534by kasperni

It looks like the difference between the Boston Dynamics robots 2016 vs 2021The 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.by Pixelbrick

They moved to motors from their older high speed hydraulics. I don't know if it was after unitree or not.by cma

why is hydraulics junk?by faeyanpiraat

Perhaps because of the potentially slower actuation speed, but you also generally get a lot more power from hydraulics so im not sure one can claim it is junk. Far less acrobatic, but also far more sumo wrestler.by AngryData

Less fit for impressive youtube videos. I'm sure they have other boring utilities for the technology.by tencentshill
