"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[1]

The Advanced Appendage Bus (AAB) was a proprietary universal socket interface utilized by Cybot Galactica[2] to connect limbs, heads and other appendages to a droid's central processor. Its dataflow was more than triple that of the Universal Socket Interface standard, which would allow for advancements in sensory input, though only Cybot Galactica-manufactured parts were compatible with AAB sockets.[1] Supporting software for the interface was developed at a Cybot Galactica-funded droid research institute located in the financial zone of the planet Coruscant's Galactic City.[3] Some criticized the company's aggressive setting of a new standard,[2] with competitors claiming that Cybot Galactica was attempting to its market share to cut smaller operations out of the lucrative droid replacement part business.[1]
