The Droideka Sentinel was a variation of a droideka modified by smugglers to protect contraband. Like its predecessor, the Droideka Sentinel was equipped with two blaster cannons, but had better firepower due to combat improvement. During the Galactic Civil War, both the Galactic Empire and the Rebel Alliance utilized it as a security droid. It was weaker than its stronger counterpart the Droideka Oppressor.
