JUBA-II. La enseñanza experiencial en un concurso de robótica

La enseñanza utilizando proyectos es una metodología activa de aprendizaje de gran eficiencia. En este trabajo se expone la experiencia de los alumnos que han participado en un proyecto muy especial, la construcción de un robot para el concurso internacional, “Laureate Award for Excellence in Robotic Engineering”. Los alumnos expondrán el bagaje competencial que llevaron al proyecto, de dónde provenía (formal o informal, reglado o no reglado, teórico o experiencial) y cómo ha contribuido este proyecto al refuerzo y adquisición de nuevas competencias y talentos, que contribuyen a una formación integral, poliédrica; tanto desde el punto de vista profesional, como personal.

The conjugate gradient partitioned block frequency-domain for multichannel adaptive filtering

The conjugate gradient is the most popular optimization method for solving large systems of linear equations. In a system identification problem, for example, where very large impulse response is involved, it is necessary to apply a particular strategy which diminishes the delay, while improving the convergence time. In this paper we propose a new scheme which combines frequency-domain adaptive filtering with a conjugate gradient technique in order to solve a high order multichannel adaptive filter, while being delayless and guaranteeing a very short convergence time.

Stability and smoothness improvements for an underactuated biped with a tail

In this work we present an important improvement in our model of biped mechanism that allows the elevation in a stable form of the system's feet during the execution of trajectories. This improvement allows for simpler trajectory planning and also facilitates the reduction of losses in the collision between the feet and the ground. On the other hand, we add to the design phase the study of the displacement of the Zero Moment Point, as well as the variation of the normal component of the ground reaction force during the motion of the system. Consideration of the above mentioned magnitudes in the design phase allows us to design the necessary support area of the system. These magnitudes will be used as a smoothness criterion of the ground contact to facilitate the selection of robot parameters and trajectories.
