Like a bird, this drone uses touch to grip branches and rest

Drones often hover in the air, noisy and whining. They can already be used for many tasks, but not when you need some quiet.

But when a drone is monitoring a rainforest, its cluttered surroundings and its own gripper arm become too tricky for its camera-based vision. Until now.
