'''Construction robots''' are autonomous floating devices capable of repairing or building the [[Player|player's]] structures. They are one of two type of floating robotic devices, the other being the [[logistic robot]]s. They run on electricity from [[roboport]]s, or a [[personal roboport]].
== Mechanics ==

Construction robots accomplish various tasks, including:

* They repair damaged entities using [[repair pack]]s.
* 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. This includes environmental entities such as [[raw fish|fish]] and [[tree]]s; [[cliff]]s can be "deconstructed" if a construction robot has access to [[Cliff explosives|cliff explosives]] in a provider or storage chest in their network, or in the player's inventory.
* They add entities marked with a [[blueprint]] or placed as [[ghost]]s as long as these entities are available.  Entities are fetched from the closest logistic chest.
* They can carry and build up to four [[tile]]s at once, depending on the researched [[worker robot cargo size (research)|worker robot cargo size]].

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.

Researching [[Worker robot cargo size (research)|more cargo]] or [[Worker robot speed (research)|more speed]] for the logistic bots are also valid for the construction robots.<br />
