PigeonBot Uses Real Feathers to Explore How Birds Fly

Researchers at Stanford University have developed PigeonBot, a flying robot with biohybrid morphing wings using real feathers to explore how birds fly. By mimicking the intricate interactions of real feathers, the robot can morph its wings for control and stability. The study, published in Science Robotics, reveals the discovery of "directional Velcro" on feathers that aids in wing morphing. PigeonBot's design allows for maneuvering using wrist and finger joints, showcasing stable flight control inspired by bird flight techniques. The researchers aim to share their findings openly to benefit society and conservation efforts. Future enhancements for PigeonBot include a morphing tail, grasping feet, and autonomous flight capabilities. This research highlights the potential for aerospace engineers to innovate by studying and emulating bird flight mechanisms, offering insights for more stable and efficient aircraft designs.
