Construction robots are autonomous floating devices capable of repairing or building the player's structures. They run on electricity from Roboports.
Construction robots accomplish various tasks, including:
- They repair damaged entities using Repair packs.
- They replace destroyed entities as long as they are available in a Provider chest or Storage chest.
- They remove entities marked with the deconstruction planner. Removed entities are transported into storage chests.
- They add entities marked with Blueprint as long as these entities are available.
Construction robots are priority targets of Enemies, meaning Biters/spitters will engage them even if there are Pollution-producing buildings around. Construction robots have no means of defending themselves and do not run when they encounter enemies. Because they often operate at the "front", they are in high danger to be destroyed. Despite being a floating entity, ground units using melee are still capable of destroying them.
