The drone looks a bit like a modernist light fixture, with a beautifully crafted wood frame and plastic shielding, and strips of adhesive tape or “humidified cotton” mounted on its lower surfaces. After being guided to a generally favorable position, it hovers above a branch to be sampled and monitors any movement like swaying or bouncing, synchronizing its approach. When it makes contact, it pushes with enough pressure to cause loose eDNA materials to transfer to the strips, but not so much that it pushes the branch out of the way. Essentially, it leans on the tree.
Super cool nature drone!
