I looked to see if I could find anything close to the IW-37 or CLL-M2 droids and discovered that I couldn't find any silhouette 2 sized droids, nor were there any lifter droids. I did find a single pilot walker in Keeping the Peace meant for cargo lifting, but vehicle stats and droid stats are two very different things.

If any of you had to stat out these loader/lifter droids, how would you do it?

I personally found that there needed to be some house ruling with encumbrance. These large droids should be able to handle pretty heavy loads without penalty, such as encumbrance 25 or even 30. The cargo hauler linked above can handle 50, and that has a pilot. I ruled that the droids would have 10 + double Brawn as the encumbrance limit, and that items like backpacks also doubled the amount they increased encumbrance limits. For a droid like these, backpacks and similar items were actually reinforced frames, stabilizing repulsors, or removable cargo pods.

Thoughts?

There is a Loader Droid in the "Debts to Pay" adventure that comes with the GM Screen.

That helps. I am guessing the assumption is that the encumbrance limit is 10, which fits with the existing rules but seems too low for droids like these.

What would one of these cost?

I beleive that encumberance only come in if you are making rolls when over your limit. A cargo lifter robot moving cargo and placinf it on a shelf should not requier a roll in normal circumstances.

For the purpose of their part in the game, i wouldn't worry about the encumbrance limit that much. Assume they can lift a crate from a ship and place it in storage.

By the looks of it, if a "lifting" roll was required then it would use the Robot's Athletics Skill, but i imagine that would only be for very heavy or unwieldy loads.

As for cost, the adventure suggests it would cost 5k to replace one.

They do not have much function or autonomy (they do not appear to have need of higher functions), but can operate on given orders or be remote controlled.
