The aerial robot presented here for the rst time was based on a quadrotor structure, which is capable of unique morphing performances based on an actuated elastic mechanism. Like birds, which are able to negotiate narrow apertures despite their relatively large wingspan, our Quad-Morphing robot was able to pass through a narrow gap at a high forward speed of 2.5m.s −1 by swiftly folding up the structure supporting its propellers. A control strategy was developed to deal with the loss of

... ability on the roll axis resulting from the folding process, while keeping the robot stable until it has crossed the gap. In addition, a complete recovery procedure was also implemented to stabilize the robot after the unfolding process. A new metric was also used to quantify the gain in terms of the gap crossing ability in comparison with that observed with classical quadrotors with rigid bodies. The performances of these morphing robots are presented, and experiments performed with a real ying robot passing through a small aperture by reducing its wingspan by 48% are described and discussed.

The radiosity method is particularly suitable for global illumination calculations in static environments. Nonetheless, for applications of image synthesis such as lighting design or architectural simulation, we have to deal with dynamic environments. To make the method usable in a real case, the illumination has to be updated as fast as possible after an object moves. The efficient way is to find the calculations strictly necessary to be recomputed after a change in the scene. The largest part

... of the computation time is spent on visibility calculation. In this paper, we investigate the possible speed ups in those calculations. We propose the use of the visibility complex for radiosity calculations. The presented study is realized for 2D scenes of convex objects in the static case. We show that the visibility complex is very suitable for radiosity calculations in this context, and that it also allows for efficient updates in the dynamic case.

... y of observations and studies is put in the perspective of the ideas surrounding them, leading to a presentation of the current classification of these motions. After showing the shortcomings of such a classification, we present, following an idea of Darwin's, the various movements in a renewed and observation-based perspective of the plant development. With this perspective, the different movements fit together logically, and in particular we point out that the mature reversible movements, such as the sensitive or circadian movements, are just partial regressions of the developmental ones.
