The mod adds a new type of mobs that were built out of redstone, by some mad scientist. This looks more like the uprising of the robots, but in the way where most part of them are actually friendly. Some of them have nice defending characteristics, but you can't control them directly, like in this Mecha robot mod. Still, I think that Redstone Robots mod for Minecraft PE 1.11.4 is definitely deserved to be in your mods list.
