Training droid

This droid was shaped as an sphere and had small blasters placed inside small holes inside its body. It was used by the Jedi Order to train younglings and padawans in lightsaber combat. During the Galactic Civil War, Jedi master Obi-Wan-Kenobi used a Training Droid to test his apprentice, Luke Skywalker's, skills in lightsaber combat, just a few short hours prior to the Battle of Yavin.
