Yes, as you can see if you watch carefully. That's disappointing. Legged locomotion technology is far enough along to make that work standalone. Maybe they could get Softbank to get them some consultants from Boston Dynamics. BD has gone to electric robots, so the people who did the hydraulic machines may be available.

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.

Says you?
