My prototype is based on a robot from Overwatch, I decided to add three main features on it a smell detector, camera lense and UV light.  How this thing work is when you initiate the drone it will automatically start detecting the smell near you. When the smell is located it will establish a route to the smell source the fastest. When the drone arrive at the source site, it will take a picture of it and start analyzing the scent. After it is done analyzing the data will display on the phone that is bluetooth connected.  Now the user can the smell in the data base.
