Thank you! I'm working on animating/rigging this fascinating hinge in Blender on a 3D mesh that I got from a CT scan off the Smithsonian. I'm aiming to eventually 3D print this as a working piece that students can touch, look at and understand in real life. Thank you again for explaining this, no I finally understand how this works.
It's a wonderful example of Newtonian mechanics, isn't it? Levers, fulcrums, forces, and so on. I hope your work enlightens future students. Next step: understanding elbows, knees, etc.
Exactly, I'm still researching the limb mechanics and wish I could show you what kind of armature I have so far to gather your input. Are you on Facebook and willing to chat? I could share my research so far better there (screenshots, bone limits, etc).
Right now I'm not sure if there is supposed to be a hinge between the Carpus and the Manus on the front legs. Assuming that this is similar between species, I already told my GF that we have to go to the local bar again and have Snow Crab Legs for dinner so that I can study the mechanism better, lol :-)
I am not on Facebook, but we could correspond by email with attachments, if that suits you. Your Crab Leg Plan sounds justified. After all, you have to establish how general your conclusions are, right?
i know people love these and many other crabs- but I'm of the general "not enough fish/crabs, etc in the sea" to eat any creatures living there. Puts the kibosh on sushi, etc., but can live without that, hoping that will help those of the briny deep survive.
Hello Walter,
I think I'm good. I found some small samples of crab skeletons at our local beach (Chesapeake Blue Crab) and was able to play with those.
I understand how the hinges work now and should be able to put that together in 3D sculpting.
Thanks again for your awesome detail on that.
I'll let you know what I have once I get it to work.
:-)

Any thoughts about why crushing claws are most often on the right, while cutters are on the left?
