Abstract

An odor-localizing autonomous air vehicle includes an airborne robotic platform having a navigation platform, a wireless transmitter communicatively coupled to a management console, and an olfactory sensor mounted on the airborne robotic platform that reacts to at least one olfactory odor. A controller is communicatively coupled to the airborne robotic platform, the navigation platform, and the biological sensor. The controller monitors the olfactory sensor. In response to the biological sensor detecting the at least one olfactory odor, the controller directs the airborne platform to three-dimensionally map an olfactory plume of the at least one olfactory odor using an olfactory-driven search pattern. The controller stores the three-dimensional map for later retrieval or transmits the three-dimensional map of the olfactory plume to the management console via the wireless transmitter. The olfactory sensor is a photonic crystal enclosure that contains plasmonic nanoparticles.

First claim

What is claimed is:

1. A bio-hybrid odor-localizing autonomous air vehicle comprising:
an airborne robotic platform;
a navigation platform coupled to the airborne robotic platform;
an olfactory sensor mounted on the airborne robotic platform that reacts to at least one olfactory odor and comprises plasmonic nanoparticles within a photonic crystal enclosure;
a controller communicatively coupled to the airborne robotic platform, the navigation platform, and the olfactory sensor, and which:
monitors the olfactory sensor;
in response to the olfactory sensor detecting the at least one olfactory odor, directs the airborne platform to map an olfactory plume of the at least one olfactory odor using an olfactory-driven search pattern,
once the olfactory sensor detects the at least one olfactory odor, the controller directs the removal of the olfactory odor from the olfactory sensor allowing the olfactory sensor to detect at least one more compound.

2. The bio-hybrid odor-localizing autonomous air vehicle of claim 1 wherein the intended use can be altered by changing nanoparticle ligands and/or the photonic crystal structure within the olfactory sensor to target specific agents.
