The TDL nanny droid represented a specific type of nanny droid, produced by AccuTronics. Its purpose was to act as both a protector and a guardian for the children of its owner.
These droids, standing at a height of 1.9 meters, were manufactured by AccuTronics to fulfill the needs of individuals who either required security for their offspring or were unable to dedicate sufficient time to their care. A typical TDL model included four arms, along with a torso covered in synthflesh designed to replicate the scent and warmth of the child's mother, and a 2-liter internal reservoir for storing milk. Notably, the TDL/XL-Lioness version incorporated a pair of hidden blaster cannons within its lower arms.
A specific TDL/XL unit was integrated with a YVH 1 battle droid, resulting in the creation of Nanna. This modified droid served as a capable nanny and bodyguard for Ben Skywalker during his parents' absences. Some years prior, Anakin Solo received protection from a TDL/XL-Lioness while he was on Anoth. This particular droid had been altered to include concealed blasters in all four of its arms.
