Abstract

Recent advances in sensor miniaturization have enabled the development of a miniaturized fully functional autopilot. In this article, the open hardware and open software Paparazzi-UAV Lisa-S micro autopilot is presented, weighing only 2.8 grams and measuring 2 by 2 centimeters. It incorporates 2-way telemetry with a ground station, a Spektrum DMS2/DSMX remote control, an IMU (Inertial Measurement Unit), a Magnetometer, a GPS module and a 32-bit 72 MHz processor for stabilization and navigation. As an illustration, the Lisa-S has been mounted on various miniature multi-rotors. Mounting it on a Ladybird quadrotor leads to a 8.5 by 8.5 cm system weighing 27 grams (excluding battery). Flight results are shown of the Ladybird performing autonomous GPSbased navigation missions outdoors.
