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.","thumbnail_url":"https://img.transistorcdn.com/dkSY09WMT3S7SiI_n-P5daFmTJplJgc8AfjEgyM1Kqg/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9zaG93/LzQxMjcwLzE2ODM1/ODI1MTQtYXJ0d29y/ay5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
