JTR-47 served as a training droid within the confines of the Jedi Temple, assisting young Jedi in refining their capabilities. Before the Battle of Naboo took place, JTR-47 played a role in guiding Obi-Wan Kenobi through the training regimen, teaching him how to harness the Force for abilities like jump, Force push, and throw, as well as fight using his lightsaber, and other techniques, including the art of disarming adversaries wielding a blaster.
Within the game Star Wars: Obi-Wan, each droid encountered during the training is designated as JTR-47. This particular write-up posits that solely the initial droid who introduces themself to Obi-Wan Kenobi is, in fact, JTR-47.
