Drones can now react to complex turbulence at the speed of light using laser-based AI hardware.
By replacing digital controllers with a photonic reservoir computer, researchers slashed training time to milliseconds and latency to nanoseconds. This allows real-time compensation for aerodynamic variables that digital systems are too slow to process.
Deep Photonic Reservoir Computer Meets UAV Control: An ultra-fast learning-based compensator for agile flight in confined space
arXiv · 2604.10262
Unmanned aerial vehicles (UAVs) operating in confined, cluttered environments face significant performance degradation due to nonlinear, time-varying unmodeled dynamics-such as ground/ceiling effects and wake recirculation-that are unaccounted for in traditional controllers. While learning based compensators (e.g., MLPs, TCNs, LSTMs) struggle with historical data dependency, vanishing gradients, and prohibitive computational costs, this work pioneers the integration of a deep photonic reservoir
