説明:

The creation of new odors by blending existing ones is usually done manually based on the human sense. To enable robots to perform this automatically, we developed an automated odor-blending system. In this system, an olfactory sensor system composed of an array of Membrane-type Surface stress Sensors (MSSs) performs odor measurement of a blended liquid, and Bayesian optimization controls the blending concentration. The actual blending of the liquid samples is performed by automated syringe pumps. Our system performs odor-blending by injecting liquid samples into a pot or by draining some of the liquid from the pot. The one-pot strategy has the advantage of reducing the amount of liquid samples used in the entire optimization task and reduces the problem of pot replacement. To implement this one-pot strategy effectively, a Drainable One-Pot Bayesian Optimization (DOPBO) algorithm was developed and applied to our system. The system was tested using a ternary liquid mixture.
