Résumé : In this paper, we apply a general framework for building complex whole-body control for highly redundant robot, and we propose to implement it for visually-guided grasping while walking on a humanoid robot. The key idea is to divide the control into several sensor-based control tasks that are simultaneously executed by a general structure called stack of tasks. This structure enables a very simple access for task sequencing, and can be used for task-level control. This framework was applied for a visual servoing task. The robot walks along a planned path, keeping the specified object in the middle of its field of view and finally, when it is close enough, the robot grasps the object while walking.
