Did you see the part where the single Tesla actuator was lifting the piano up and down?
Yes but if you're statically holding it that's going to burn out motors etc? And just because it can, doesn't mean it's better.
But anyway it was just a general question. It doesn't seem self evident to me that electric motors are 'better' so I was just wanting someone to chime in and explain.
Excavators etc use hydrolics, presumably for a reason.
I suppose if you want dexterity? But then you'd lose load carrying?
