Repair drone (Red Alert)

The repair drone is a simple, ingenious piece of technology. Essentially a multi-purpose maintenance and repair bot using two VTOL turbofan engines, a mechanical arm that can be equipped whith a cutting laser, welding device or just grabbing claws, a few solar panels and basic AI routines designed for one thing: repairing and arming vehicles.

The similar technology is seen in Red Alert 3 as well. Allied Armor Facility, Allied Airbase, Allied Seaport, Imperial Mecha Bay, Imperial Docks use repair drones to regenerate damaged friendly mechanical units within a short range. Soviet counterparts do not have these tiny machinists, however Soviet Crusher Crane does, with a larger cover range.

Still, there are two modifications in Red Alert 3. First, repair drones become universal, can fix every type of friendly mechanical units in range, not as in Tiberium Wars they are focused on units produced by the certain kind of buildings themselves attached to. Second, in Red Alert 3 each unit can be assigned with only one drone, and the repairing efficiency is slower. If the main building as attacked by Desolator AirStrike, repair drones will be temporarily unavailable.
