I saw this and, whereas it's not exactly news, it is the best article I've seen on this particular application.http://technology.newscientist.com/article/dn14718-robot-spyplanes-get-new-role-as-medical-couriers.htmlOddly, the design they've gone with
Read more…Does anyone know of a sensor (not too expensive) that could let a UAV know it’s altitude relative to the ground height not sea level? I guess what I am asking is…..Is it possible to hold a UAV’s altitude at say 400 feet above the ground regardless of
