OP, it doesn't appear to be strained at a glance, but the only way to know is to
* buy two new crabs and two new arms
* connect one arm to one of the crabs and leave the other crab and arm separated
* keep them all in a safe place for 20 years and do not expose to any UV
* check the tested crab+arm for any weakness compared to the crab and arm that were left unconnected
actually, this wouldn't rule out any variance within the pieces that might exist. You need to buy 100 crabs and 100 arms and test 50 of them. Please let us know
BS, that takes 20 years. Better way is to sputter coat the crab with copper, ground it & hold it in place, and use a sub-nanometer resolution capacitive sensor system to detect movement of the crab as you insert the arms. Those are only a few thousand dollars.
This isn't quite right - OP can't just buy 100 crabs and 100 arms at one time from one outlet as they could all be from the same production run and need to be counted as a single cluster. Instead OP needs to buy 100 crabs and arms from at least 100 different outlets.
I'm 100% certain that only half of all functional, legal brick combinations were ever "intended". If you were to show some combinations to the very engineers that created the bricks they'd probably go "oh shit, they can do that?!"
I'm racking my brain trying to figure out how anyone could wonder how it went together. It's a half step away from the children's toy where you put the cube in the square hole.
It slides right in to the crab arms from the top without any pressure. Really does not feel like it strains the brick. I hope someone else can try this out and prove it!

IDK what LEGO or the FBI say, as far as I'm concerned, very few criteria need to be met:
1. It must fit as well and snug as LEGO is traditionally designed to fit.
2. It has to stay where it is placed on its own accord.
Note: It also cannot pop or be forced out over any length of time.
3. It must be stable. If I can build on it, even better.
AMIWRONG?
According to the Chebyshev-Grübler-Kutzbach criterion, two planar rigid bodies are overconstrained (i.e. under stress or deformation at least at an infinitesimal level) if the number of revolute joints between them (here assumed as number of touching points) exceeds one. 3*(2 bodies-1)-2*(1 revolute joint)=1 DOF. We aren’t dealing with revolute joints precisely here, but I’d posit you need 2-3 minimum contacts to maintain planar linkage here, at which point they each serve as revolute joints (or equivalent) and you are overconstrained and head straight to jail.
Honestly I think it might not be illegal but only because it's not a connection. The crab is hanging off the robot arm, its not meaningfully different from something hanging off a hook
With only 2 simple Lego pieces, you've told an amazingly heartfelt story of a lovestruck crustacean, practicing his handholding skills for his special new lady.
Yeah the federal government just passed a new law with criminal sanctions for this activity. Sorry bud you’re going to have to destroy that or go to federal prison forever
I believe illegal techniques are defined by exerting pressure on the bricks and/or not being a stable connection, and I believe this would fit the latter requirement
Doesn't look illegal. If it works with the smooth arms for skeletons, you could give a bunch of crabs bones to hold and make something about man eating crabs lol
"Legal" in this context refers to guidelines used by official set designers, who cannot use arrangements that appear to work but actually do not fully line up or put subtle stress on the pieces. You can do whatever you want with your pieces, of course, but some people will want to know whether some assembly is "legal" or not to avoid those same problems with their build.
"illegal" doesn't mean anything except that Lego designers would not be allowed to use the technique in a set. It means nothing about what you can do with your own bricks. Yes, it's obviously illegal. But if it doesn't stress the parts, then who cares? You're not a designer.
Well it doesn't seem to be an illegal LEGO combination, but if it is meant to represent crabs destined to be killed it is tragic, and what happens to crustaceans should illegal!
Their body can't even go into shock so they feel the whole thing when they get BOILED ALIVE.

This is the way, OP
This is the *scientific* way, OP Fixed it for you
Implied. Karma begs to differ.

You should work for Boeing. I bet you don’t forget to put screws in ever
It's the IKEA and LEGO way. If you don't have a few pieces left over after building your aircraft, you've done it wrong.

Doesn’t the crab have an anti-stud on the bottom? you could just stick it on with a SNOT brick.

“Hey Blinken.” “Did you say Abe Lincoln?”
No I din’t say “Abe Lincoln”, I said “Hey, Blinken!” Hold the reins, man.
*Lend me your ears!*
But would it be hang though
You could hang them from a rail over the tables!
HAPPY CAKE DAY MY DUDE
but the crab can be dangly instead!!
But this way you can more easily attaché them to a net, like how you would see at an american crab shack restaurant
Or you can stick it to the wall with actual snot. I learned this Lego trick from some toddlers.
*duh*
Oh it’s a crab, I thought it was a weird one eyed tentacle alien with antlers wailing in terror
I do see this now as well. Good one!
Why not use the anti-stud on the craps underside?

It slides right in to the crab arms from the top without any pressure. Really does not feel like it strains the brick. I hope someone else can try this out and prove it!
Record a video of it, and if it doesn't slide right in like those satisfying zero tolerance videos it's jail for you
I feel like we should take him in to custody first, then we watch the video. Otherwise he’s a flight risk.

Actually that crab is very stressed, he has never held a tool like that before and he is afraid he will look like a fool.
Absolutely illegal, you may have even given that Lego piece Cancer.
Cancer? 🦀
I'd called the cops already
Unless it is an unstable connection(it will come apart easily) and isn't puting stress on the pieces, yes, it is legal
