Schiano, F. (author), Alonso-Mora, J. (author), Rudin, K. (author), Beardsley, P. (author), Siegwart, R. (author), Siciliano, B. (author)In this paper the problem of estimation and correction of wind effects on a quadrotor UAV, without using wind sensors, is discussed. A large body of research addresses the effects of wind on a quadrotor, however most of them consider it only as a disturbance in their control loop and, for this reason, they solved the problem compensating for the...conference paper 2014

Sagar, J. (author), Visser, A. (author)For Micro Aerial Vehicles (MAVs), robust obstacle avoidance during flight is a challenging problem because only light weight sensors as monocular cameras can be mounted as payload. With monocular cameras depth perception cannot be estimated from a single view, which means that information has to be estimated by combining images from multiple...conference paper 2014

Jankauski, M. (author), Shen, I.Y. (author)A dynamic model of an insect wing is developed treating the wing as a deformable body subject to three-dimensional finite rotation about a fixed point at the base of the wing. Discretization of a stationary wing is conducted via finite element analysis to determine the natural frequencies and mode shapes of the wing. By formulating and...conference paper 2014
