In an article recently published in the journal Applied Sciences, researchers proposed a hybrid fuzzy proportional-integral-derivative (PID) controller for quadcopter drones used in agriculture ...

Using the SDK, users can implements a median filter, a complementary filter, and PID algorithms, effectively allowing them a full range of possibilities in the functionality of their drone.

It’s got the usual trappings of a drone, but with only a single rotor ... to deal with the unique forces on the craft and tuned the PID loops accordingly. Check out the results in the video ...
