Unmanned aerial vehicles (UAVs), also known as drones, can help humans to tackle a variety of real-world problems; for instance, assisting them during military operations and search and rescue missions, delivering packages or exploring environments that are difficult to access. Conventional UAV designs, however, can have some shortcomings that limit their use in particular settings.

For instance, some UAVs might be unable to land on uneven terrains or pass through particularly narrow gaps, while others might consume too much power or only operate for short amounts of time. This makes them difficult to apply to more complex missions that require reliably moving in changing or unfavorable landscapes.

Researchers at Zhejiang University have recently developed a new unmanned, wheeled and hybrid vehicle that can both roll on the ground and fly. This unique system, introduced in a paper pre-published on arXiv, is based on a unicycle design (i.e., a cycling vehicle with a single wheel) and a rotor-assisted turning mechanism.

Researchers at the Nanjing University of Aeronautics and Astronautics turned to artificial intelligence (AI) to simulate aerial dogfights using hypersonic aircraft. In the simulation, the aircraft flew at speeds between Mach 5 to Mach 11 or up to 11 times the speed of sound, the South China Morning Post.

The advent of drones or autonomous vehicles has already changed the nature of warfare today. During the ongoing conflict in Ukraine, Russia has successfully deployed cheaply assembled drone swarms to attack critical infrastructure.
