We will explore people’s mental models of robot scent. To this end, we will conduct exploratory human subjects research on scent-to-robot matching and controlled experiments of different scents for different robots. This work is sure to spark research on robot aroma and olfactory interaction. The results may be used in the design of robots that work closely with people, such as in the workplace, in the home, as (aroma)therapeutic robots, and in customer service settings, especially at storefronts.
