Ethanol-Sniffing Robot (2 of 2)

Caption

This robot can out the source of an ethanol leak in a clever way. Rather than just following the strongest scent, the robot plugs measurements of concentration and airflow into a complex partial differential equation and then decides where the most useful position to take another measurement is. By repeating this process, it can find an ethanol source in just a dozen or two tries in a complex environment with multiple sources.
