Here are some photos of my most recent project, a crop-surveying UAV. It will have a small camera on the bottom to measure reflected infrared light from plants, which I’ll be using to create NDVI images. This will allow farmers to see which areas of their fields are photosynthesizing the most.
The bottom right photo is the autopilot board I’ll be using, a PXFmini. I chose it because of its small size, and integration with the Raspberry Pi I’ll be using to take photos. I’ll also be connecting a GPS and compass module to the PXFmini, as well as a telemetry radio for remote monitoring.
Also, courtesy of seven on #xkcd, I have a name for the UAV: Cropter. I’m considering getting some stickers made to show this name on the wings or tail.
Hobbyking Trainstar airframe
2.2Ah 3S Lithium Polymer battery
PXFmini autopilot with GPS and telemetry radio
Raspberry Pi Zero with NoIR Camera
Hobbyking T6A 2.4Ghz transmitter
I chose the hardware to be as minimal as possible while also remaining light to increase flight time.
Side Note: If any of you have recommendations for stitching a series of still images into a very large photo, please recommend them in the comments. Thanks!
