Obviously, you could animate something like this by hand but is there any software on Linux meant to simulate this kind of mechanism?
You can do it just in the sketcher and get 90% of the way there with just sketcher constraints. You can also create a body with a subshape binder for each sketch line and use assembly and create an animation. You don't even need 3d solids. I created a gif, we'll see if it attaches properly to this reply...
