- faeyanpiraat 8mo agowhy is hydraulics junk?
- AngryData 8mo 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 8mo agoLess fit for impressive youtube videos. I'm sure they have other boring utilities for the technology.
- Pixelbrick 8mo agoI look after one at a University that gets used for teaching & outreach & there's definitely no hydraulics on the thing.
- cma 8mo agoThey moved to motors from their older high speed hydraulics. I don't know if it was after unitree or not.
