Projecte de la Comissió EuropeaINTELLACT - Intelligent observation and execution of Actions and manipulations (EC-FP7-269959)
A method to perform cleaning tasks is presented where a robot manipulator autonomously grasps a textile and uses different dragging actions to clean a surface. Ac- tions are imprecise, and probabilistic planning is used to select the best sequence of actions. The character- ization of such actions is complex because the initial autonomous grasp of the textile introduces differences in the initial conditions that change the efficacy of the robot cleaning actions. We demonstrate that the action outcome probabilities can be learned very fast while the task is being executed, so as to progressively improve robot performance. The learner adds only a little over- head to the system compared to the improvements ob- tained. Experiments with a real robot show that the most effective plan varies depending on the initial grasp, and that plans become better after only a few learning itera- tions
