ABSTRACT
The current challenges defined for robots require them to automatically generate and control a wide range of motions in order to be more flexible and adaptive in uncertain and changing environments. However, anthropomorphic robots with many degrees of freedom are complex dynamical systems. The generation and control of motions for such systems are very demanding tasks. Cost functions appear to be the most succinct way of describing desired behavior without over- specification and appear to underlie human movement generation in pointing/reaching movement as well as locomotion. Common cost functions in robotics include goal achievement, minimization of energy consumption, minimization of time, etc. A myriad of approaches have been suggested to obtain control policies and trajectories that are optimal with respect to such cost function. However, to date, it remains an open question what is the best algorithm for designing or learning optimal control policies and trajectories in robotics would work. The goal of this workshop is to gather researchers working in robot learning with researchers working in optimal control, in order to give an overview of the state of the art and to discuss how both fields could learn from each other and potentially join forces to work on improved motion generation and control methods for the robotics community. Some of the core topics are:
- State of the art methods in model-based optimal control and model predictive control for robotics as well as inverse optimal control
- State of the art methods in robot learning, model learning, imitation learning, reinforcement learning, inverse reinforcement learning, etc .
- Shared open questions in both reinforcement learning and optimal control approaches
- How could methods from optimal control and machine learning be combined?


FORMAT
The workshop will consist of presentations, posters, and panel discussions. Topics to be addressed include, but are not limited to:

- How far can optimal control approaches based on analytical models come?
- When using learned models, will the optimization biases be increased or reduced?
- Can a mix of analytical and learned models help?
- Can a full Bayesian treatment of model errors ensure high performance in general?
- What are the advantages and disadvantages of model-free and model-based approaches?
- How does real-time optimization / model predictive control relate to learning?
- Is it easier to optimize a trajectory or a control policy?
- Which can be represented with fewer parameters?
- Is it easier to optimize a trajectory/control policy directly in parameter space or to first obtain a value function for subsequent backwards steps?
- Is less data needed for learning a model (to be used in optimal control, or model-based reinforcement learning) or for directly learning an optimal control policy from data?
- What applications in robotics are better suited for model-based, model-learning and model-free approaches?

All of these questions are of crucial importance for furthering the state-of-the-art both in optimal control and in robot reinforcement learning. The goal of this workshop is to gather researchers working in robot learning with researchers working in optimal control, in order to give an overview of the state of the art and to discuss how both fields could learn from each other and potentially join forces to work on improved motion generation and control methods for the robotics community.
