Repair Bot

Repair Bots are a block built onto a vehicle, fortress, or structure, which aid the unit in repairing damage done to itself. Upon taking damage, a construct will release small flying drones, the Repair Bots themselves from the Repair bot blocks. The Bots will seek out damaged parts of the ship, and once in close enough proximity, will begin repairing the damage.

Usage
Repair bots can be placed anywhere on the constructable, excluding turrets and spinblocks. It is not mandatory to provide a clear path to the damaged area, since the bots themselves are cosmetical only and repairs are conducted without them. Therefore the bots cannot be destroyed unless the main block is taken out.

Note that materials are needed to repair blocks. These are taken from the local/global resource storage, depending on your campaign settings.
