Hubdroid

Hubdroids were droid models used by the Galactic Empire. The droids were employed in Accresker Jail to ensure loyalty among the prisoners held there. If a convict strayed too far from or tried to destroy their designated hubdroid, bombs implanted in their uniforms would detonate.

Hubdroids were also used in Fortress Vader to perform menial tasks such as cargo transfer.
