In the past few years, we have covered drones that carry a wide variety of items. Transporting poles can be quite challenging though. Researchers have come up with an aerial robot (Geranos) for this very purpose. It grabs poles at their center of mass to reduce the effect of inertia. It requires only 2 actuators for gripping.
This drone can transport poles up to 2m in length. It weighs 3kg and has under 5cm placement accuracy.
