Ukraine now has killer robots with machine guns

Honestly, I don't see it. The "military/industrial complex" would produce something far more sophisticated than this. This looks like a "robot" cobbled together from TinkerToys and a surplus weapon. It's something that I would expect the Ukrainians to build for themselves in a home workshop, and I doubt if the second one would look the same inasmuch as it might be cobbled together with other parts in the olde scrap pile. Oh, and it looks kind off top heavy, doesn't it? I'd expect that someone would have to dash from cover every few minutes to put it back on its wheels...
