China claims its FPV drone algorithm can beat best pilots in aerobatic manoeuvres
Chinese researchers have allegedly developed a new algorithm that lets first-person-view (FPV) drones perform autonomous aerobatic manoeuvres better than those by veteran human operators during flight missions. Inspired by sparrowhawks, falcons, and bats, the new artificial intelligence (AI) upgrade can facilitate high-speed, high-risk movements that usually only the most skilled human pilots can execute. Traditionally, FPV drone performance has been improved by upgrading hardware (stronger motors, better sensors). However, with the latest attempt, scientists instead focused on smarter software, using advanced motion planning and decision-making algorithms to unlock next-level performance. "This biological wisdom—transforming 'high-risk manoeuvres' into 'high-survival rewards'—holds the key to redefining traditional drone flight paradigms," said Gao Fei, an associate professor at Zhejiang University and one of the scientists associated with the project, while speaking to the South China Morning Post. According to the team, the new FPV AI has two main components. The first is a motion-intent translator that converts a pilot's desired manoeuvre (e.g., a flip or loop) into specific, executable drone commands. The second is a risk-reward evaluation that analyzes the trade-offs between safety (avoiding obstacles), efficiency (energy use), and performance (aerobatics). Essentially, these give the drone the 'brains' to understand what it needs to do. "Conventional methods focus on enhancing hardware performance, employing more powerful motors or higher-precision sensors, yet few have systematically investigated the rationality of manoeuvre-planning itself," explained Gao. "We have demonstrated that quadrotor drones can unlock more sophisticated flight manoeuvres and graceful postures solely through intelligent algorithms alone—no hardware upgrades required," he added. The algorithm also enables the drone to perform tasks efficiently and avoid crashing, all without needing GPS or remote human input. What's more impressive is that the team's claims about its new drone brains are not just theoretical. During ensuing trails, the drone flew through tight obstacle courses, even inverted, with hummingbird-like agility. In a one-on-one test, it beat a professional human pilot with a perfect success rate of 100% versus the 12.5% exhibited by the pilot. 'We believe that aerobatic flight can enhance a vehicle's adaptability and flexibility in complex environments, improving its performance in practical applications,' Gao said. The AI-enabled FPV drone also executed smoother, tighter manoeuvres with less recovery time between stunts. This level of autonomous aerial acrobatics has significant implications beyond having fun with races. It could, for example, have military applications, enabling drones to be far more agile in urban or forested environments, evading detection and striking with precision. Navigating tight or dangerous spaces like collapsed buildings or volcanic vents would also greatly benefit search and rescue operations. It could also be used in filmmaking and space missions. 'Examples include deploying probes near volcanic eruption vents, rapidly exploring narrow gaps in collapsed buildings during disaster rescue, and enabling spacecraft to navigate space debris," the team observed. "It could also significantly benefit aerial cinematography by allowing drones to autonomously capture smooth, stable footage," the researchers added. However, the new system is not foolproof. For example, the algorithm currently requires a pre-mapped environment to plan paths. It also cannot yet support drone swarms or real-time adaptation to unknown terrain. The scientists are hopeful that further research would open up "new possibilities for quadrotor drones to perform aggressive missions in extreme environments."

Chinese algorithm beats veteran human controller in FPV drone race
Chinese team has developed a unique algorithm that gives first-person-view (FPV) drones the ability to perform autonomous aerobatic manoeuvres, unlocking their full potential to outperform humans in intense flight missions. Advertisement The breakthrough was published on April 16 in the peer-reviewed journal Science Robotics. Aerobatic flight, as the name suggests, involves high-risk manoeuvres that require unstable postures – movements rarely executed in conventional flight operations for most aircraft However, in nature, aerial acrobatics are a vital skill for many species. For instance, sparrowhawks and falcons can rapidly adjust speed and direction through vertical or inverted flight to hunt or avoid obstacles. Bats excel at mid-air flips and hanging upside down, while ravens perform complex aerobatics to attract their peers.
