Controlling a swarm of drones with NodeJS
summary
Code sends UDP commands from Node.js and consumes raw telemetry to close a feedback loop; control is Node.js over UDP so messages drop and timing matters. Cheap indoor quadcopters use a downward camera and mission pads for absolute positioning so relative X/Y plus pad coordinates produce world positions. A small React HUD coordinates four drones and gets them to dance in formation most of the time but telemetry noise, drafts, and crashes remain common.
