The COLIBRI Project - Subsystem Improvement

This paper highlights the main features of the COLIBRI project aiming at constructing a flapping twin-wing robot of the size of hummingbird (Colibri in French), actively stabilized in pitch and roll, and capable of hovering. The prototype has a total mass of 22 gr, a wing span of 21 cm and a flapping frequency of 22 Hz. The paper discusses some recent improvements and on-going works.
