That's surprisingly not a lot for something that size.
The arms have a large extension and seem relatively delicate.
So it'd basically just a versatile but limited crane with a novel UI
That depends on its dexterity. Can a crane use tools, weld, rivet and so on? Certain not. But this machine m, once refined could plausibly do all of those things and is seen using some kind of grasper tool.
Yes and no. It really depends on how fast and accurately you want to move that much mass. I worked on a mobile robot years ago that weighted ~5000lbs. It was only putting 2mL of fluid into a tile on the space shuttle at a time. It needed to be that heavy because it had to be very careful not to damage the tiles (or the shuttle) and it needed to move in and out of the same standard height doors at the orbiter processing facilities that people walked through, but then needed to operate at up to 13' in height.
That robot had a pretty extensive supporting human team. As technology improves, I hope it could be more self-sufficient, but that video did not demonstrate a clear savings vs meatbags.
Seems like the "savings" come from keeping people in a safer, predictable ground location.
Humm... that U-shaped piece it's lifting looks like it was custom made for this robot, but doesn't appear to fit anywhere.
But then, what matters here is how much fun they had designing the robot!
You can literally see the same u-shaped thing on the next portal, it's used to keep the power feeding wire up.
But I guess, what matters here is how much fun you had on writing your snarky comment ;)
Wow you guys would be great friends! That's what really mattered ... not the snarky comments, but the friends we made along the way :)
