Constructor Sentinels are a specialized variant of Sentinel whose primary function is to repair damaged Forerunner structures.[1][2][3]
Overview[edit]
Design details[edit]
Constructor Sentinels have tall and narrow chassis, relative to their overall smaller size compared to most Sentinels. They feature two primary housings, with one located directly above the other, often joined by a connecting arm. Atop their upper housing is a pair of ear-like appendages.[1][3][4] Perhaps the most integral feature of Constructor Sentinels are their small reconstitution emitters,[1] which can be located in its upper housing, lower housing, or between the two, depending on the variant.[Note 1] Each Constructor Sentinel also features a tiny smartmatter loom and a low-tier ultrascanner, as well as an impulse drive for locomotion.[1]
Constructor Sentinels are manufactured in Ferrarius Assembler Vats within dedicated manufacturing facilities on Forerunner installations and worlds.[1]
Operation[edit]
These small utility drones operate in coordinated groups to diagnose basic faults, weave minor repairs into existing Forerunner structures, and retune hard light structural elements. Vast numbers of Constructor Sentinels may cooperate with Strato-Sentinels to complete large-scale repair operations.[1] Steward Sentinels maintain their own complement of Constructor Sentinels for repair, preventing deterioration and compromise of the much larger Sentinel.[5] For the purpose of repair, the Constructor's primary tool is its small reconstitution emitter. The beams fired from the reconstitution emitters can also be used to interact with Forerunner technology, allowing them to open Cryptums[6] or lower the shields on pistons. The latter functionality allows the Constructor Sentinels to access the tunnel networks built within Sentinel Walls.[3][7] Although low in power output, one of these beams can cause harm if an organism if its crosses the beam's path.[3]
One or more Constructors will often be summoned if something within their facility is damaged. Once attracted, they appear to require little prompting to follow someone seeking their assistance. In one instance, a member of a Spartan-IV fireteam simply had to state that they had a task for a Constructor to get it to follow them, with no other obvious methods of coercion being used.[4] Constructors can be programmed for other tasks, such as awakening a Guardian Custode, with little difficulty, being reprogrammed within minutes.[8]
Constructors can also play the role of a security grid. When a Constructor is attacked, a signal is automatically sent to Sentinel emitters to begin deploying Aggressors. For this reason, they form an excellent security perimeter. However, with no weapons systems of their own, the Constructors must rely on Aggressors when threatened.[3]
Variants[edit]
Multiple distinct variants of Constructor Sentinel exist. Presumably, each Forerunner facility has its own unique variation of the Constructor Sentinel, as is the case with the Aggressor Sentinel.[1]
A chassis of the Constructor Sentinel encountered on Installation 00, Installation 05, and Partition. This variant's reconstitution emitter is located in its upper housing.
A chassis of the Constructor Sentinel encountered on Sanghelios and Genesis. This variant's reconstitution emitter is located between its upper and lower housings.
