Mating objects together

Hello All
I am looking to see how too mate different things together and be inter active like a robot arm
everything is connected but everything moves

If the purpose is to make an animation, look into Bongo.
Else you could try to define the movement of each object in plain Grasshopper or experiment with the Kangaroo2 plugin for Grasshopper to define hinges and such.
