A gesture-controlled drone is a three-stage pipeline, not a one-liner. Stage 1: detect hand landmarks in real time (MediaPipe gives you 21 keypoints per hand). Stage 2 is the part most tutorials skip and turn those landmarks into a discrete gesture (open palm, fist, pointing), using either simple finger-state rules or a small neural net, with a buffer so noise doesn't fire commands. Stage 3: map each gesture to a drone command and send it over the drone's SDK (djitellopy for a DJI Tello), wrapped in a safety layer. Detection is the easy 20%. Classification, debouncing, and safe command mapping are the 80% that actually flies.
