‘PigeonBot’ unveiled and can bend its wings like a real bird

Could pigeons be the model for a new generation of flying robots? That’s what the researchers who built PigeonBot, a robotic pigeon with actual feathered wings, seem to be betting. Having birdlike wings could help airborne machines make better turns in tighter spaces, such as in dense urban environments or forests, a roboticist who was not involved in the study explained to Science News. Researchers extended or bent the wings of dead pigeons to determine how the birds control their wing shape. As Science News reports, the experiments showed that the angles of two wing joints have the biggest impact on the alignment of a wing’s flight feathers. The orientation of those feathers, which aid the bird in flight, help determine the win ...
