It looks to be around 10 meters on a side.  Hopefully it won't need to do too much maneuvering during the operation (whatever that is ).

It is bigger than anyone speculated, about 40 feet on a side. So great to finally see the thing. Also, looks like it will be dragging it cord.

There's no pictures of the hole, but this one makes it pretty clear that they replaced the center panel.

That could easily be paint. The edges are fuzzy. The color matches other repainted areas such as under the light/generator stand.

No, they have definitely replaced two deck plates there, but I don't see any signs of a change of material or anything suggesting anything other than general maintenance and a coat of paint.

Presumably the steel was getting roasted/warping from repeated touchdowns in exactly the same spot...  and that's an incredibly nice problem to have! :)

With sufficient thrust, pigs fly just fine - however, this is not necessarily a good idea. It is hard to be sure where they are
going to land, and it could be dangerous sitting under them as they fly overhead.

An umbilical..  What did you expect?  That it'd be wireless?  It has to get power and comms from somewhere.

And here is a picture that reddit user aftersteveo just posted of the roomba on the deck of Of Course I Sill Love You.

The picture tells an interesting story. Look at the circular tread marks on the deck - and the rectangular dark ones. Also note that the "X" is freshly painted on the deck.

They seem to have been maneuvering it already, I don't think these tracks and others are from tele-handlers or person-lifts. Give a clue to the running gear underneath, as of the large motors at the periphery.

Its got 1600 square feet of deck area. Even at a much small size, i would have thought it would have onboard power even when I thought it would be a lot smaller. A gen set and tankage could be worked in there no problem, WIFI for the coms. So yeah, I am a little surprised it isn't cordless.

I think Elon knows a guy who could help battery power the thing...

I think the two rectangular dark areas on the "Beast" are tracks for moving...

Doubt it. It's too low profile for a genset and tankage. Plus, why bother? There's plenty of power in the generators for the ASDS already...

Given that it doesn't have far to go and only has to get out unassisted (not back), I just don't see the need for added complexity.

It might or might not have it's own power supply, but this umbilical could also provide a tether to keep the thing on deck if gets caught outside in a blow..

I think you are correct. The gear that is along side of the tracks definitely looks like the drive train. The track marks on the deck are probably from the lifts and tele handlers they use.

I'm just amazed at how much it looks like what we thought it would look like.  Perhaps I shouldn't be??

Not that I'd expect anything less from NSF...  Nothing (much) to see here.. move along!  ;)  ;D

Yes!  Flying Beaver's model is nearly perfect, except for the four meter tall guy on the side!   :D
Once that is fixed and the pistons are angled inward instead of outward, it's like he knew someone on the design team.
Well done FB!

Large, it is...

It looks like the area in the middle, between the four arm "shoulder" points - is what most of us came to think it would look like (I originally was in the "Four little weld-down robots" camp.

It dwarfs the grade-all that's next to it...

Top-center is a red-colored pipe-looking thing.  Fire suppression?  Or some random tool bag.  Really hard to tell.

Bottom-center is a mine-me shop vac.  Cute.

The four shoulder joints are mounted exactly where the Roomba is not thick - the four wells.  And then everything else extends way around both the shoulders and the tracks.  Head scratch.

Do we see a structural similarity?  Unit slides under the stage, latches onto the launch lugs/restraints, and assuming the unit is near center to the barge "locks down" the combined cradle and the rocket!

One other thought...maybe what we are looking at is a pre-cradle concept leading to bigger things to come?

Yep.  But big it needs to be to secure a stage that's even bigger.  :)

Top-center is a red-colored pipe-looking thing.  Fire suppression?  Or some random tool bag.  Really hard to tell.

My money would be on the random tool bag.  ;)

The four shoulder joints are mounted exactly where the Roomba is not thick - the four wells.  And then everything else extends way around both the shoulders and the tracks.  Head scratch.

If they're going to do anything much with those hold-downs, they'll also need a good deal of lateral support to ensure this thing can't possibly tip over in any direction when hanging onto the stage - hence the really low ground clearance, heavy duty surround and a myriad of bolts to hold it all together.

It'll be great to see this gadget in action.  Presumably it'll be front-and-center in the next landing telecast.. can't wait!


EDIT:  Although it needs to be heavy to stay on board, it does seem that they went to a bit of trouble to not make it TOO heavy - hence the holes in the side-structure.  The hole in the middle has me intrigued though - maybe that's simply weight-reduction also?

I'm thinking...
With no cover over the tracks, that perhaps the tracks can be raised, to lower the deck. (Similar to raising the wheels on a lawnmower). This would  lower the base directly onto the deck. The track axles then only need to support the weight of the Xoomba. The jacks would be able to transfer the rocket weight straight through to the deck.

Nautical feet.  And lots of them.  I'm still recalibrating.

It is certainly thick enough to transfer bending loads from side to side.
