I can show you how to rig it, but it must be grouped correctly before rigging can start. By correctly I mean that each part ('actor' to be) that needs to articulate must have its own unique group, each part should consist of only one group, and the groups should have names that make some sense, eg "lClaw1", "rClaw2", "rCal2PistonRod", etc. Until you get to that point (lets hope you are there already) you can't start rigging.
