BIonicle MOC BDR-R.A.R.U.

This is for the first round of 's BDR contest.

BDR-Biological Destroyer Robotics.
RARU-Resource and Ammo Retrieval Unit.

Primary Function: retrieval, transport and displacement of resources, resupplying fuel and/or ammo to fuel and/or ammo based BDR's.
Secondary function: Signal boosting and rerouting.
Alternate form: transport arachnid
Weapon: head-mounted gun turret, tail.

R.A.R.U.'s are often seen with micros and builders for when one of these other two units deem a damaged BDR "unsalvageable" one or more of these unites will come in and pick out the valuable components of the BDR or retrieve the ammo if present to resupply ammo based weapons on combat BDR's. It can also obtain fuel for flying or spacebound BDR's. Its front mounted gun turret allows for basic self defense, combat, and protection or repair BDR's The dishes located on its tail can receive and rebound command signals to the surrounding BDR's. The R.A.R.U was created as a multi-functional BDR with its internal construction designed to retrieve materials, absorb and displace liquids, and its electronics designed for optimal signal boosting. To retain mobility these BDR's are not heavily armored, making them more susceptible to damage, but compensate by being predominantly black for stealthier operation at night.
