confused

Hey
I just started blender but im a bit confused
I have a bunch of armatures linked to each other forming a kinda leg ( Theo Janses mechanism) but I can’t make to join an empty point which supposed to be a joint thing. They are seperate and if I rotate the parented wheel thing the whole thing just goes around and the empty point is in 1 place instead of moving nicely. Where is my mistake?

Thanks,

the tutorial btw:

“bunch of armatures linked to each other, forming a kind a leg”

a little hard to diagnose a problem based on that! still, while not being a rigging expert, i would start with this question:

but since you said you were a newbie - did you extrude each bone from a starting point? that way they are naturally linked. maybe you just created separate bones?

i cannot see the video since i am at work and all streaming media gets blocked, so not sure what it told you to do.
