Robotics facility

The robotics facility is a protoss structure which transports automated war machines to battlefields to support protoss forces. Each is controlled by a highly trained Master of Robotics as well as dozens of protoss engineers. The platform of the structure is designed to warp in and maintain massive units.

StarCraft II
The robotics facility creates robotic units like the colossus, observer and warp prism, as well as the immortal.

Legacy of the Void
In the single-player campaign, the player can upgrade their robotics facilities and stargates into warp robotics facilities and warp stargates, allowing them to warp-in units anywhere with pylon power identical to the warp gate.

Co-op Missions
Artanis, Karax and Alarak are able to build robotics facilities in Co-op Missions. At Level 8 Artanis acquires the talent Warp Haromonization, transforming his robotics facilities into warp robotics facilities. They also benefit from the Superior Warp Gate talent, allowing Artanis to warp in multiple units from a single robotics facility.

Development
During the StarCraft beta, the robotics facility had a different appearance. Its final model was re-used from a canceled structure known as the maintenance bay.

In the course of updating the robotics facility's design, it was decided to alter the shapes so that different animations occurred depending on the unit being produced.
