Around 22 BBY, after Count Dooku decided to test Grievous by luring a Republic strike team — made up of Jedi General Kit Fisto, Jedi Knight Nahdar Vebb and a squad of clone troopers — into his lair, Grievous used this droid to spy on the unwelcome visitors as they traveled through the corridors of his castle. The droid was later destroyed by Kit Fisto after he used his lightsaber to cut it in half.
