Are the leg structures carbon fiber or aluminum?

This video is also a bit creepy. Just picture human skulls under the feet.
For a quick oneoff prototype like that, in that shape and machining…i say aluminum. But impossible to be 100% sure without a closeup.
For energy conservation ( batteries) i would use cf. But since his is hard wired power probably aluminum.
That is one bad dude!
It would take a lot of power useage to keep heavy aluminum body and legs moving for very long.
Is that an 8" subwoofer on his body? LOL
when those robots are out of the lab for field testing etc, they have gasoline powered generators on board.
