General Atomics International

General Atomics International is a pre-War company that mass produced robots up until the Great War. The company is most well known for their Mister Handy, Mister Gutsy, and robobrain robots, as well as for the construction of nuclear power plants and generators. These were used in many vaults and in the American war robot, Liberty Prime.

Mister Handy
Mister Handy was produced by General Atomics International as a house-keeping and defensive robot, able to help out around the house and defend itself and possibly others with its buzzsaw and flamethrower. Mister Handy is speech-capable, communicating in a polite English accent.

Mister Gutsy
Mister Gutsy is a modified Type-II Mister Handy designed for military use by the U.S. Army. Mister Gutsy comes with a plasma weapon, flamethrower, and significantly better armor than Mister Handy.

Robobrain
The robobrain was created by GAI as a military robot for the US. It uses a real organic brain as its processor. Military models are capable of using integrated laser weapons, sonic projection rays, and have human-enough manipulator claws to wield submachine guns and rifles.

General Atomics Nuclear Power
GAI made Vault-Tec Vault power systems, according to a terminal in the Citadel.
