ONLINE COVER Winging It. Bioinspired robotics translates fundamental biological principles into engineering design rules to create robots that perform like natural systems. Inspired by how birds demonstrate agile and efficient flight through wing morphing, Chang et al. studied the skeletal and feather kinematics of the common pigeon to develop a soft biohybrid aerial robot, called PigeonBot, with underactuated feathers that can steer by morphing its wings with wrist and finger joints. This month's cover is a composite image showing the range of PigeonBot's wing morphing—the wings of this biohybrid system are composed of real pigeon feathers. [CREDIT: ERIC CHANG/STANFORD UNIVERSITY]
