I am not even remotely an expert, but I do I have an idea of the power needed. Humans, and all animals rely on food as a energy source. Humans in particular are truly astonishing on endurance and how far they can run. A group of natives Indians in Mexico hunted deer by just chasing them down until the deer fell over from exhaustion. A race held in England is against men on foot against men riding horses. It is about 50-50 as to the winners of men on horses vs a man just running cross country long distances.

I have to just guess that it requires several HP of energy to make something like those robots walk or run. Just powering up to run the computers drains power faster than a laptop computer. It has to have a zillion power using sensors, and then the motors that power the motors for movement.

I imagine they measure the power consumption of the robots in The kilowatt-hours. Those robots have to suck some power. And that power has to be cooled, as all energy conversion produces waste heat.

I think it was Neil deGrasse Tyson that calculated that a "real" Terminator's power use would require a cooling radiator much bigger than the terminator itself just to operate from the heat generated by running. Everyone knows the Tesla has a water cooled battery, a big cooling system.

Maybe I am way off base, but I suspect it will be many more decades before one of those robots has a functional run time of more than an hour or two.
