The TTS-15-series education and tutorial droid was designed for educational purposes. It was used when attending a regular academy was impractical or undesirable. Marketed to "those who view education as a serious, critical period of an organic life", Industrial Automaton created the droid, which was a mixed success. Though inexpensive to purchase, the original product run was for an on-lease basis, with no option to purchase the droid. For a start up of five hundred credits and an annual renewal fee of one thousand credits, the droid was primarily targeted for sale to wealthy nobles, or as a low cost teacher for budget strained educational centers.
