Robotics Factories reduce the time taken to construct buildings but not research times nor that of defensive structures. The base time required for construction is divided by (1 + level of Robotics Factory). The formula for calculating the percentage of original build/upgrade time is (example: Level 1 Robotics factory is 50% original time, and Level 1 + 1 = 2, and since The cost of Robotics Factory doubles for every level, the building cost formula for the next level being: Base cost is 400 metal, 120 crystal and 200 deuterium. * Shipyard (Level 2) * Nanite Factory (Level 10)
