                                                      Abstract

    We formalize decision-making problems in robotics and automated control using continuous MDPs and actio ns
    that take place over continuous time intervals. We then approximate the continuous MDP us ing finer and finer
    discretizations. Doing this results in a family of sys tems, each of which has an extremely large action space,
    although only a few actions are “interesting”. We can view the decision maker as being unaware of which
    actions are “interesting”. We an model this using MDPUs, MDPs with unawareness, where the action space is
    much smaller. As we show, MDPUs can be used as a general framework for learning tasks in robotic problems.
    We prove results on the difficulty of learning a near-optimal policy in an an MDPU for a continuous task. We
    apply these ideas to the problem of having a humanoid robot learn on its own how to walk.
