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 https://www.youtube.com/watch?v=tf7IEVTDjng

So 5 years of progress within a year.
- tw1984 7mo agospot 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.
- faeyanpiraat 7mo agowhy is hydraulics junk?
- AngryData 7mo agoPerhaps 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.
- tencentshill 7mo agoLess fit for impressive youtube videos. I'm sure they have other boring utilities for the technology.
- Pixelbrick 7mo agoI look after one at a University that gets used for teaching & outreach & there's definitely no hydraulics on the thing.
- cma 7mo agoThey moved to motors from their older high speed hydraulics. I don't know if it was after unitree or not.
