For decades, scientists have been trying to create machines that mimic the way birds fly. A team from Stanford University has gotten one big step closer.
The team created the PigeonBot — a winged robot that it says approximates the graceful complexities of bird flight better than any other robot to date.
When a bird is soaring through the air, it dramatically changes the shape of its wings as it makes hairpin turns and swoops up and down. Birds change the shape of their wings far more than planes do, and the complexities of bird flight have posed a major design challenge for scientists trying to translate the way birds fly into robots.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
