Finding Stuff in the Sky
Playing with RC planes, we quickly determined that it was necessary to track objects which are moving throughout a large area. We needed to keep contact with the object, in our case, the planes since we had a video transmitter within the plane. Thus, had to create an antenna tracker that would scan the sky for a signal and then focus the antenna on our plane. We created this using a microcontroller system hooked up to servos and the antennas and developed a system wherein a spiral path is followed to map out all possible areas. We prototyped it with LEDs and and a phototransistor.
