@zaruba_tech: Drone or submarine? Why not both? 🌊🚁 The hardest part is crossing the invisible border between air and water. In the air, fast-spinning propellers keep the drone flying. On the water, rotating propellers turn downward, slow down, and pull the drone beneath the surface. Then it resurfaces and flies again. This kind of hybrid drone could open a new future for underwater research, rescue missions, and exploration in places humans cannot easily reach. ⚡
