I cannot help to lament in the lack of ambition from Japanese people nowadays. They seem content with cute ideas which has little relevance to major global problems and tech advancement. They still have a top notch scientific and research system, and produce great results every year. But they seem completely lost the drive for building the actual things that can affect people.

Out of interest, since you’re in a mood to generalise, which nation’s people are worthy of your respect for their ambition and focus?

It is interesting to think of a future where wars between countries could be fought through duels between "champion robots" with no loss of innocent people's lives. EDIT: I didn't expect this comment to be controversial/downvoted, and it is interesting that it is evoking some level of passive aggressive sarcasm.

This is the same idea as letting two sides play chess and see who wins. It might work for trivial matters, but when the stakes are high and the chips are down human nature is always going to lead to force to get what is important. "Ok so our robot beat your robot on some contrived fight. We're going to invade your country with a population of millions, take all of your money and possessions and force you all to work…

I think it was Kissinger that said (paraphrasing) war is a tool to achieve political objectives. The necessity, scale and manner of violence depends on what those objectives are and feasibility of success.

The kind of political dilemma that would be solved by a mecha duel would probably not be the same one that requires invasion and enslavement in death mines.

Kissinger may have said it, but it dates back to, at least, Carl von Clausewitz. https://de.m.wikipedia.org/wiki/Carl_von_Clausewitz:

“Der Krieg ist eine bloße Fortsetzung der Politik mit anderen Mitteln.”

(“War is the mere continuation of politics with other means”)

The dutch only pretend to be tolerant so they can deviously spend all year learning your foibles and then remind you of them, at length and in company, come December.

    Burgermannetjes don't mind foreigners at all
    Because who could expect THEM to doe normaal?
(Grapje, natuurlijk! We owe dutchies a great deal: the Puritans were afraid their children would grow up too tolerant in the netherlands, and consequently hightailed it to the New World...)

Anyone like Elon Musk, Jeff Bezos, Zuck, even Bill Gates...

Can you name 1 Japanese person who had similar ambition and commitment to large-scale projects?

If you didn't notice, most of the footage was shown at 4x speed, or 2x speed. It's extremely slow to move any part of this monstrosity. There is no way it would be capable of walking freely with the slowness of the mechanics. It's a completely different story at this scale, Boston Dynamics doesn't have a way to make that work.

Yes, even if they wanted to, making joints which can withstand such dynamic loads, while being small, and lightweight will be a giant engineering challenge. 60t static load, now imagine how big will it be when it walks.

It takes serious engineering. And it's been done.The Dragon, from Zollner Elektronik AG.[1] About a third of the size of Gundam, mostly so it could be transported by road. True quadruped. Best engineering in the giant robot space so far.

The Sultan's Elephant [2] was bigger, but less technically advanced. The headaches of transporting it were too much of a problem. Once your art project gets bigger than what can be moved by road or rail, there's a problem.

The Land Walker, from about 2006, was about a third of the size of the big Gundam. Biggest walking biped to date.[3]

There's also Eagle Prime, which is really a tracked vehicle.[4]

None of the videos you linked to show any robots actually walking.

[1] - the dragon is rolled around on a wheeled platform. There is one clip of a leg lifting, but none of it actually walking.

[2] - The Sultan's Elephant is moved around on wheels. It doesn't walk.

[3] - That thing is "skating" around on wheels, again not actually walking.

[4] - And yet another machine that doesn't walk but actually rolls around on treads.

No, the Zollner dragon really walks.[1] Very slowly, and only one foot is off the ground at a time. Top speed 1.5mph.

The wheeled platform is for transport.
