受蜜蜂启发 可控飞行的最小无线机器人问世

Core Insights - Researchers at the University of California, Berkeley have developed the world's smallest controllable flying robot, measuring less than 1 centimeter in diameter and weighing only 21 milligrams, aimed at applications such as pollination and exploration of confined spaces [1][3] Group 1: Technology and Design - The new flying robot is equipped with two micro magnets and operates using an external magnetic field for power and flight control, overcoming challenges of integrating power sources and control electronics into a tiny device [3] - The robot's design resembles a small propeller, with the magnets allowing it to hover, change trajectory, and target small objects, similar to how bees collect nectar [3] Group 2: Future Developments - Current limitations include the absence of onboard sensors for real-time position detection, which may lead to deviations in flight path under sudden environmental changes; plans are in place to add active control features for better maneuverability [3] - The research team aims to reduce the robot's size to less than 1 millimeter, enabling control through weak radio waves, and is also developing a 5-millimeter "swarm" robot capable of collaborative tasks, potentially for medical applications such as thrombus ablation [3]
