RoboFly: An insect-sized robot with simplified fabrication that is capable of flight, ground, and water surface locomotion [article]

Yogesh M Chukewad, Johannes James, Avinash Singh, Sawyer Fuller
2020 arXiv   pre-print
We describe the new design in detail and present results demonstrating these capabilities, as well as hovering flight and controlled landing.  ...  It also has a lower center of mass, which allows the robot to additionally land without the need for long legs, even in case of unstable flight.  ...  ACKNOWLEDGMENT This work is partially supported by the Air Force Office of Scientific Research under grant no. FA9550-14-1-0398.  ...
