Smellicopter is a drone technology and innovated by PhD student Melanie Anderson and team from the University of Washington

The Smellicopter can do two things -it can smell odors and follow those to the source but it can also avoid obstacles while doing that.  The main thing is the antenna right here. This is an antenna from a live moth -   the smelling organism of the moth - and it serves as the odor sensor for the drone.The antennas is kind of like a tube so what we're able to do is take really thin metal wires and stick those into the ends of the antenna.So this has some floral scent.When the antenna gets activated from odors then you're able to measure that electrical signal as a spike.So the Smellicopter when it smells odor, then it travels upwind and when it loses the odor  then it casts crosswind until it picks up the odor again.We weren't really sure if that was ever going to work,so the first time it worked it was really amazing (laughs)In the future this drone could be used for finding gas leaks and buildings or finding  unexploded IEDs. So you could send out a bunch of drones and not have to endanger any human lives. Being able to locate the source of an odor is a huge field, so by taking  basically the best - by using the moth antenna - which is super fast, low powered, highly sensitive even if that's not the long-term goal, it's something that man-made sensors actually can't do.
