The Tesla robot is a Vault-Tec security robot model implemented in the company's Secret Vault. Like its fellow security robots, it is a three-legged orb-like walker. Tesla robots use powerful electric blasts generated by special Tesla device mounted on them to attack possible threats to the well-being of the Vault. However, no security robots could protect the Secret Vault from an army of super mutants. There are some Mr. Buddy consoles in the Secret Vault Laboratory 3 which could be used to buy three special Tesla robots, which could be used against super mutants by the Initiate.
