I was following a kitbashing and rigging course over at Digital Tutors for a mechanical insect, but I decided to put my own spin on it and adapt the design into a spider and throw in a bunch of extra animatable mechanisms.
I have a crippling fear of spiders, but for some reason I really like them when they're mechanical. I guess then I'm free to admire the enginuity in their forms.
...Their disgusting, demonic forms >: (
I enjoy rigging. I'd like to be better at it, but I enjoy it.
I gave each segment of each leg a piston structure so the legs can elongate to about twice their starting length. I split the abdomen case into panels and attached them to the inner workings with a series of pistons, allowing each panel to rotate and translate in all axes, giving it that twitchy, insectoid vibe.
