I see a similar video some year ago .... and I'm quite sure no idraulic motor on that robot .... so that it seems to me they have come a long way in a few years in reality .... that I know the motion control in the hydraulic drives is not as flexible as you can see in the video .... I think there are many innovations in engines and valves here .
