Unlocked Tech:


The Robotics Bay (often abbreviated to Robo Bay) is a structure on the Protoss Technology Tree that unlocks the Colossus unit at the Robotics Facility. It also contains three upgrades for Robotics Facility units: the Gravitic Boosters speed upgrade for Observers, the Gravitic Drive speed upgrade for Warp Prisms, and the Extended Thermal Lance attack range upgrade for the Colossus. The Robotics Bay can only be created after the Robotics Facility has been warped in.

Like most Protoss structures, the Robotics Bay can only be warped in at a location powered by the Psionic Matrix. It can only research upgrades while it remains within the Matrix, otherwise it becomes unpowered and cannot function. However, even an unpowered Robotics Bay still allows the creation of the Colossus.
