This is our first successful check of the systems necessary to take over the commands of the quadcopter and land on our target. We are using an APM2.6 and a ordinary Logitech camera connected to video processing routines. With the data we pass it through a PI controller and override the controls(roll, pitch) of the APM to center on the target. We will soon make a real test to check the correct tracking, but we are broke right now. The end game is an automatic landing system for battery replacement.
