Droids designed for rescue operations were categorized as rescue droids; these are a type of droid. A specific model of rescue droid, known as the pill droid, was employed by the Galactic Republic in the High Republic Era. Specifically, pill droids were put to use following the Great Hyperspace Disaster, participating in the initial rescue attempts within the Hetzal system and the subsequent events.
Following the collapse of the Great Assembly on Serenno upon the Jedi Padawan Dooku and Lady Jenza of Serenno, an event triggered by a groundquake caused by the Tirra'Taka, a number of rescue droids that could hover were dispatched to find their location.
