International sales of drones is expected to soar from fewer than 4 million in 2015, to nearer 20 million this year and beyond. Many are for personal use but today we're looking at the way scientists are using them in research projects over difficult terrain. One of New Zealand's experts in drones is Dr Barbara Bollard-Breen.
To talk science Lynn Freeman also spoke to Barbara’s colleagues: Professor Steve Pointing who's the Director of the Institute for Applied Ecology and Dr Michelle Dickinson who heads the Nano-mechanical Research Laboratory and writes and performs as Nanogirl.
