The Tesla robot is a Vault-Tec security robot model implemented in the company's Vault-Tec Corporate Vault.

Vault-Tec also developed a special bodyguard programming called "Mr. Buddy" for Tesla robots, probably to help scientists from the laboratories to feel much more safe when going up into the Wasteland or doing research on living subjects. However, "Mr. Buddy" was never finished and left in a Beta state.

There are some Mr. Buddy consoles in the Vault-Tec Corporate Vault Laboratories which could be used to buy three special Tesla robots, which could be used against super mutants by the Initiate.

Mr. Buddy Variations

Robo-bud MK-I

Cost : 10000 caps

This one looks and acts exactly like a normal Tesla robot but a little more powerful.

Robo-bud MK-II

Cost : 50000 caps

This one is a bit larger than normal Tesla robot, and also stronger and resistant.

Prototype robo-bud MK-X

Cost : 100000 caps

This one is a prototype, improved model of Tesla robot. Surprisingly, it's even smaller than normal Tesla robots, only a bit bigger than service robot. But the MK-X is the strongest of them and could obliterate many super mutants in few seconds.


Tesla robots appear in Fallout: Brotherhood of Steel.


  1. Fallout: Brotherhood of Steel Official Strategy Guide p.92: This class of Robot was created to serve as the clean-up crew. Once Sentry and Patrol Robots have detected an intruder, the Tesla 'droids are sent in to deal the real damage with deadly energy weapons. Unless you're fast and well-protected, one zap is enough to cleave your health bar in two.
