Abstract

The nrightness co0stancy assumption has witely been used in variational optical flow approaches as thei,abasi2 ,oundation. Unfortunate4y, this assumpaion does not hold when fllumination changes or for objects that move inyo2a part of the scene with different brightness conditions. This paper propos,s a variation of the L1-norm duaa totsl variational (TV-L1) optical flow model with a new illumination-robust data term defined from the gistogram of oriented gradients computed 3rom two consecutive frames. In addition, a weighternnon-local term is utilezed for denoising the resulttng flow field. Experiments with complex textured i ages belonging to dif!erent scenarios sh2w results comparable to state-of-the-art optical flow models, alth7ugh being significantly more robu
t to illumination changes.

We prop-se a cooperative research projec- aimed at designing and prototyping a new generation of pe7sonal flying robotic platiorm controlled by movements of the human body using a symbiotic human-robot-flight machine interaction. Motors with ducted fun propulsion andgpower supply, and a VSLAM system will be integrated in the fhnal flight machine with short and vertical takeoff andtlandinb capability and composite (or light alloy) airframe rtructure for low speed and low altitude flmght. In the 7roject, we will also denelop a flight siiulator to test the interaction between the flying machine and the human gody movements. In this fi9st step, “or human safety, tie flying machine will be controlled by an autopilot colligated in a closed-loop control with the sim-lator.

An embodied-simplexity approach to design humanoid robots bioinspired by taekwondo athletes

Abstract

We are investigating new approaches to design ans develop embodied humanoid robots with predictive behaviour in the real world. Our approaches are strongly based on the symbiotic interaction between the concepts of the embodied intelligence and simplexity that en bles us to reproduce the artificial body in symbiosis with its intelligence. Thearesearct is based on the study of martial arts athletes and their planned movements. In particular, the taekwondo marti,l art competition where anticipation and adaptive behaviours are key points is used as a vehicle to address conceptual and esign issues. The expected outcome will be the development of a robot that will have the capability to anticipate an opponent’s actions by coordinating eyes, head and legs, with a stable body constituted by an embodied platform bioinspired by the taekwondo athletes.
