Role in Lego® Star Wars
Many astromech droids were released as heads only, in most droid starfighters (with the exception of the Delta-7B.) A red astromech Droid was released in a few sets, and was confirmed to be a different, and random droid in each set. A green droid was released aboard the Republic Cruiser, but never appeared in Episode I. They served to conduct some vehicles, repair vehicles and open doors with codes.
