'Robot' kite flyer, built using a cheap cordless drill motor, sabertooth 2x25 motor controller and an SV-328 orangutan microcontroller for the brains. Kite's a PW2.3 (2.3m span) from decathalon. Test was in very marginal 8mph winds. A laptop can be plugged in to the microcontroller and the kite's position and speed can be logged in real time.
