PigeonBot is a robotic bird outfitted with real pigeon feathers that move to reshape its wings like an actual bird. Developed by researchers in Stanford's LentinkLab, the remote-controlled PigeonBot demonstrates how morphing wings improves flying agility. (Video below.) Their resulting technical paper is the cover story in the current issue of the journal Science Robotics. From Science News:
Birds can modify the shape of their wings by fanning out their feathers or shuffling them closer together. Those adjustments allow birds to cut through the sky more nimbly than rigid drones....
Researchers bent and extended the wings of dead pigeons to investigate how the birds control their wing shape. Those experiments revealed that the angles of two wing joints, the wrist and the finger, most affect the alignment of a wing’s flight feathers. The orientations of those long, stiff feathers, which support the bird in flight, help determine the wing’s shape. Based on those findings, the team built a robot with real pigeon feathers, whose faux wrists and fingers can morph its wing shape as seen in the pigeon cadavers.
My buddy Ken Goldberg, a UC Berkeley professor of robotics, his 10-year-old daughter Blooma, and science communicator Ashley Chase wrote a delightful children’s book called How to Train Your Robot! Illustrated by Dave Clegg, the story, about a fourth grade robotics club, is a fun and understandable introduction to how deep learning can help robots […]
Shimon, the robotic maestro from Georgia Tech’s Center for Music Technology, is releasing an album and going on tour. To write lyrics, the robot employs deep learning combined with semantic knowledge and rhyme and rhythm. Shimon has also had a complete facelift giving it a much more expressive mug for singing. In IEEE Spectrum, Evan […]
IEEE Spectrum asked pioneering roboticist Rodney Brooks, co-founder of iRobot and former head of MIT’s Computer Science and Artificial Intelligence Laboratory, the eternal engineering question: “What is a robot?” Inspired by computational neuroscientist Warren McCulloch who enjoyed writing sonnets, Brooks responded to the query in iambic pentameter. Here’s the beginning: What Is a Robot? By […]
So…exactly how many times a day are you singing Happy Birthday to your sink? Unless you’re among the most germaphobic among us, it’s unlikely you ever thought the simple act of handwashing would start to take on such a central role in our daily lives. Of course, with all the touching and such, bar soap […]
Paralysis by analysis. It’s the phenomenon that happens when you’re so stuck on thinking through all the ramifications of your actions that you don’t actually take action in the first place. That can happen with all this free time you’re spending stuck inside your house. With literally every home-bound option available to you, it’s easy […]
At this point, it’s every single person’s responsibility to reduce their own carbon footprint and transition to a more sustainable lifestyle. But if you consider the grim fact that the biggest culprit of greenhouse gas emissions from human activities in the U.S. is burning fossil fuels for electricity, things, like pivoting to metal straws and […]
