Father Builds Child-Tracking Quadcopter To Accompany His K

Wallich shared the details behind his design with engineering magazine IEEE Spectrum, but the project is actually a pretty simple one — the copter is a fairly standard build that Wallich got airworthy easily. Getting the gizmo to follow his kid was a little more tricky, as an RFID solution would have necessitated a burlier antenna than the small craft could comfortably carry. Instead, Wallich used a navigation program that kept the copter a set distance away from the GPS beacon it was following. He even strapped a camera unit to the thing for full eye-in-the-sky capability.

Nice surprise about this shorter form. Can you tell us what it is you are talking/writing about?
Has any info. about this shorter form been posted before (and i just missed it)?

Interesting. Hope that thie child will also make a more and more powerful robotics in future.
