Wanted to know if they made any real advances in muscle actuators so I looked this up. They're pneumatic, and the model in the photo barely moves and doesn't stand on its own. An article said they will switch to hydraulics in the future. Neither pneumatics or hydraulics is efficient enough to be useful in a standalone human sized machine, so this looks like more of an art piece aimed at fleecing some idiot venture capitalists.
To be fair. They are really dumb and easy to fleece. Remember Elons "robots" that were just people in suits.
They have been upgraded to puppets. Humans are still needed for operation.
Are humans technically hydraulic with all the blood and such?
Think spiders are.
No hydraulic would imply using fluid pressure to effect work whereas we use electricity to contract and relax muscle fibers
While muscle contraction is triggered electrically (or electrolytically, considering the role that ions play in action potentials) the physical force of the contraction is generated by a mechanochemical process.
