ROB 64 is the robotic operator of the Great Fox mothership in the Star Fox series of video games. In the Japanese version of the series, he is called NUS 64.

Though his full name is ROB 64, he often referred to as just "ROB." ROB has the ability to completely control the Great Fox, making the ship fully autonomous. ROB is also networked to the ship's main computers, allowing ROB to process any information requested by the Star Fox Team. ROB can also use the ship's transfer device to send vehicles and items to Star Fox team members in the field.

ROB was nearly destroyed in Star Fox: Assault when Peppy Hare crashed the Great Fox into the shield protecting the entrance to the Aparoid Queen's lair, but Peppy and ROB managed to find an escape pod before the ship was destroyed.

ROB is an inside joke in the Nintendo universe. He is a satire of the failed NES accesory R.O.B. the Robotic Operating Buddy.
