??? 機器鳥飛上藍天?????
????You could be forgiven for thinking the robot bird is real, especially when seen from a distance. ????This energy-efficient robot, weighing just 500 grams, captures the elegance* of a bird in flight. ????The robot, named SmartBird, has just been unveiled by Festo, the robotics company known for its bionic animal designs. ????It has previously created penguins* that can communicate with each other to avoid collisions* and a robotic elephant’s trunk* designed to grip objects and safely interact with humans. ????SmartBird is modeled on the herring gull and can take off, fly and land while its flight is controlled remotely from the ground in real time. ????To take off, the robotic bird flaps its wings with the help of an onboard motor. As the wings beat, the front edge also twists, enabling airflow along the wings to generate thrust*. ????Once in flight, the tail acts as a rudder* to steer the bird through the air. ????The technology could be used to design “stroke wing generators” — devices that produce energy from water.
