SB-series Sentinel Droid

The SB-series Sentinel Droid was a model of security droid made by Balmorran Arms.

Appearance
The SB unit has a roughly humanoid body, with a crescent-shaped head and a visor for an eye.

History
Balmorran Arms created the SB-series Sentinel droid to address the needs of private owners around the galaxy. The droids could retract their limbs when deactivated, but if they are activated, they could extend their limbs and scan the area for intruders. If they detected intruders using the security scanners located in their visors, they could open fire on them with a palm-mounted laser cannon. The SB-series unit eventually found use with contractors, who used them to demolish buildings, thus giving them the nickname, "Wrecker droids."

Trivia
This droid is an expanded version of an unidentified droid seen in "Star Wars: Droids."
