We are trying to make 5~10 helicopters automatically track the movement of people and follow after them. Syma S107g is the model we are testing with. It looks like the one below.
First, We don't know how to control more than 2 helicopters at the same time in the same space. The manufacture only offers 2 frequency channels to allow 2 same models to fly at the same time was default.
Second, We are looking for a small sensor, which is attached to a part of each person so helicopters can track their movement and follow. we wonder if theres anything as such within the Arduino kit.
