Abstract
[Resumen] Este artículo propone un sistema de control visual
directo basado en imagen para guiar a un
manipulador móvil. El robot está compuesto por una
plataforma móvil diferencial con un brazo de 7 gdl
(grados de libertad) y una cámara en configuración
eye-in-hand. Como se describe en el documento, la
información visual se emplea para guiar tanto el robot
manipulador como la plataforma base durante el
seguimiento de trayectorias definidas en el plano
imagen. A diferencia de los enfoques anteriores, el
sistema propuesto en este documento emplea un
control visual directo para guiar al manipulador
móvil. De esta forma, el controlador genera
directamente los pares (fuerza y momentos) que se
aplicarán al manipulador y la plataforma base
teniendo en cuenta la dinámica del robot. Este
artículo describe los diferentes componentes
cinemáticos y dinámicos del controlador propuesto y
se valida a partir del seguimiento de trayectorias de
imágenes repetitivas y no repetitivas.
[Abstract] This paper proposes a direct image-based visual servoing system for the guidance of a mobile manipulator. The robot is composed of a mobile differential platform with a 7 dof (degrees of freedom) arm and an eye-in-hand camera. As described throughout the paper, the visual information is employed to guide both the robot manipulator and the base platform for the tracking of image trajectories. In contrast with previous approaches, the one proposed in this paper employs a direct visual servoing system for guiding mobile manipulators. In this case, the controller directly generates the torques (force and moments) to be applied to the manipulator and base platform taking into account the robot dynamics. This paper describes the different kinematic and dynamic components of the proposed controller and it is validated during the tracking of repetitive and nonrepetitive image trajectories
