Jedi Praxeum protocol droid
From Wookieepedia, the Star Wars wiki.
The Jedi Praxeum protocol droid was a golden protocol droid deployed in Luke Skywalker's Jedi Praxeum. It greeted Kyle Katarn in the hangar bay of the Praxeum upon his arrival, informing him that Skywalker was waiting upstairs.
[edit] Behind the scenes
The Jedi Praxeum protocol is canonical, as it appears in Jedi Knight II: Jedi Outcast, but has not been named. It has some dialogue with the player. Although it resembles C-3PO, it is not him, as its voice is much lower.
