B2EMO, also known as Bee-two or Bee, was a groundmech salvage assist unit that served the Andor family for years. The weary old droid used his many tools to tow scrap for members of the human family, including Cassian Andor, who eventually went on to join the Rebel Alliance. B2EMO was squat and boxy, a red machine with black sensors that used mecanum wheels to travel towards his destinations.
