What flying machine has roller blades and can hoover?

The flying machine you're describing is likely a type of personal aerial vehicle or drone designed for short-distance travel. These vehicles often feature hover capabilities, allowing them to take off and land vertically, similar to a helicopter. The addition of roller blades suggests a design element that enables ground mobility, making it versatile for both flying and moving on the ground. While various prototypes exist, such vehicles are still largely in the experimental or conceptual stage.
