Animate parented object to move in a certain way when parent object moves itself?

Question

This is the machine in question whose movements (1.35 -1.38, source: https://www.youtube.com/watch?v=WfpfpzknBo8&t=1m28s) I'd like to replicate via applying armature.

My mesh:

How do I rig the other 3 limbs so that they move exactly as that machine does in that Youtube link I earlier poster? Thanks

@moonboots informative answer, and I'll refer to it in the future. Now, for my question, when I parent objects to another, I cannot get the parented to move in a certain way when the parent moves. — Francis Mike Nathan, Aug 8, 2022 at 2:47
