The laser robot is a Vault-Tec security robot model implemented in the company's Secret Vault. Like its fellow security robots, it is three-legged orb-like walker. The laser robot is the most powerful of all Vault-Tec security robots and uses fast-shooting laser canons to destroy its enemies. They appears a bit similar to gun robots, but have green-colored parts on them. They often appear when someone touch a green security laser, which is designed to summon a laser robot to a specific location.
