How is it possible you’re intentionally choosing to exclude Sharpies “S-Gel” line of pens brought to you by Sharpie? 🤨🤨🤨👎🏽

This robot can fly just like a real bird: It’s called PigeonBot II, and it’s designed to replicate the natural flight mechanics of real birds, achieving rudderless flight through biomimetic morphing of its wings and tail. Its design incorporates 52 real pigeon feathers, providing lightweight, elastic stiffness and natural aerodynamic properties, allowing for smooth, continuous morphing. Weighing approximately 300 grams, comparable to a real pigeon, the robot is equipped with small propellers for propulsion, allowing it to ascend, cruise, and descend effectively. Its control system uses a Proportional-Integral-Derivative controller to manage real-time adjustments to flight dynamics by combining wing asymmetry, tail tilt, and lateral deviation for optimal performance. Unlike traditional aircraft that rely on rigid structures like vertical tails for stability, PigeonBot II uses adaptive morphing controlled by a reflexive feedback loop that mimics the neuromuscular reflexes of birds, enabling it to stabilize and maneuver even in turbulent conditions. PigeonBot II demonstrates remarkable stability without a vertical tail, reducing radar signature and enhancing flight efficiency, and it has proven its adaptability by maintaining stable flight in turbulence with intensities up to 12%. The robot’s reflexive control system enables it to autonomously take off, navigate, and land, successfully executing complex maneuvers like circling flights across various wing and tail configurations, from fully spread to tucked postures. These innovations position PigeonBot II as a model for advancing aviation, offering potential applications in the design of rudderless aircraft with reduced drag, enhanced stealth, and increased efficiency, as well as inspiring the development of more agile drones and uncrewed aerial vehicles. By bridging biology and robotics, PigeonBot II not only provides a mechanistic understanding of bird flight but also lays the groundwork for innovative engineering solutions that blend natural principles with cutting-edge technology.
