The behavioral circuitry matrix was the combined mechanical and neutronic subsystems that produced droid behavior. The matrix was split into two modules—the obedience-rational module and the sensory-response module. The obedience-rational module governed the logical and social behavior of the droid while the sensory-response module controlled the droid's systems including audio-visual circuits, an olfactory-speech center, a gyro-balance unit, a spectrum analysis unit, and an extremity control system. The behavioral chips of several upper-end droid models were built using Vonium, a precious metal.
