Robotic birds are nothing new. But not many of them can change their wing shape to fly with more agility. PigeonBot is different. It has soft biohybrid morphing wings with feathers underactuated by wrist and finger motion.
PigeonBot has 42 degrees of freedom to control the position of 40 connected features with 4 servo-actuated joints. This approach makes the robot interactions safer and the wings more reparable.
