The bots appear to unlock normally with IR, as the military tech is not changed. However, Robot Army only works well when starting a new game, due an error in the migrations file of it. With and without IR, it did not load on an already existing game. This is a bug on their part, which won't be fixed in this mod.
What will be done is the recipe changes as not all recipes works, due the vanilla items being unavailable, and there is 1 military tech removed. But the stuff don't even reach that tech.
Also, from the mod maker:
-- deal with unlocking the recipes just piggy-backing on military research for now. most droids need more advanced research to build them anyway.
