Em TeeDee

Em TeeDee was a small protocol droid created by C-3PO for Lowbacca, who was beginning training at the Jedi Academy on Yavin IV. The small robot speciallized for translated Shyriiwook into Basic and vice versa. Em TeeDee originally did not have any repulsorlift engines, and had to be carried around on Lowbacca's belt. But eventually, Threepio installed it with these mechanisms, and followed Lowbacca anywhere. Em TeeDee's eyes turned into lights to illuminate dark hallways, understood over six languages, and its casing resisted minor shocks, say it was dropped on the floor. Cyberbot Galactica also showed interest in its design, but has so far not made a droid like it.
