This is such a facepalm for the US. We challenged them to a
paintball match in what's basically a glorified tractor with some CO2 cannons. There's not even a fucking remote interface, keep that in mind for the next bit.
The Kuratas has fully articulable five-digit manipulators available, as well as "hand" operated weapons. The drive system has four independent wheels on articulated legs, and includes the ability to raise or lower the center of gravity for the robot as well. Japan, being a bunch certifiable badasses, not only said "yes", but asked to have a melee competition instead of a super lame paintball fight.
This is a genius move, because as mentioned above, the US robot sucks giant metallic nuts. Having zero ability to redistribute its weight, no manipulator attachments, using continuous track propulsion, the Mk II is
unequivocally ill-suited for melee combat. It requires
two humans to be in the cockpit to operate at the moment, so there's no way it could safely fight in its current state to begin with. I doubt they could even make the needed adapatations, let alone develop the new systems they'd need to get to where Kuratas is now, within 12 months.
I just hope these losers accept help from the thousands (millions?) of knowledgable, patriotic, US roboticists and mechanical engineers who actually know what the fuck they're doing so we don't get too badly embarrassed next summer.
