I have suggested this in the past.

How about a tutorial to rig the mech from Kurts mech and mech texturing tutorials?

I modeled and textured this guy some time ago but the modeling pose kind sucks as it looks as though it is going to topple over. Manually posing the thing is a pain and besides it would be nice to animate it.

I have tried on numerous occasions to rig this thing so I can pose it but it is just too complex for me to figure out. This interaction of the pistons on the legs gets me all wrpaped around the axle and I never get to the point of thinking about to tubes and cables.

I have been directed to other rigging tutorials but they generally show how to parent basic components together and have simple rotation / position relationships and do not come close to covering the tricky elements of rigging this mech - primarily the pistons in the legs, and the flexible tubes and cables.
