- "The transition to AAB is all about moving forward with technology. USI has served well, but its time has passed. AAB more than triples the data-flow which will allow advancements in sensory input, perhaps allowing advanced tactile functionality for droids and prosthetics in the near future."
- ―Illia Setag
The Advanced Appendage Bus (AAB) was a controversial, due to it being proprietary, interface for droid appendages that was created by Cybot Galactica. Supporting software for the bus was developed in a droid research institute on Coruscant. It was meant to succeed the Universal Socket Interface on Cybot's droids.
