The growing capabilities of learning-based methods in control and robotics have precipitated a shift in the design of software for autonomous systems. Recent successes fuel the hope that robots will increasingly perform varying tasks working alongside humans in complex, dynamic environments. However, the application of learning approaches to real-world robotic systems has been limited because real-world scenarios introduce challenges not arising in simulation.
In this workshop, we aim to identify and tackle the main challenges to learning on real robotic systems. First, many current machine learning methods rely on large quantities of labeled data. While raw sensor data is available at high rates, the required variety is hard to obtain and the human effort to annotate or design reward functions is an even larger burden. Second, algorithms must guarantee some measure of safety and robustness to be deployed in real systems that interact with property and people. Instantaneous reset mechanisms, as common in simulation to recover from even critical failures, present a great challenge to real robots. Third, the real world is significantly more complex and varied than curated datasets and simulations. Successful approaches must scale to this complexity, be able to adapt to novel situations and recover from mistakes.
As a community, we are exploring a wide range of solutions to each of these challenges. To explore the limits of different directions, we aim to address in particular questions about the trade-offs and potential necessity of particular design aspects via included panel discussion as well as the invited presentations:
- Transfer learning (simulation - sim2real, multitask, different domains, etc)
- Explicit methods for planning, prediction, and uncertainty modelling
The primary focus of the submission lies on tackling these challenges resulting from operation in the real world. We will encourage submissions that experiment on physical systems, and specifically consider algorithmic developments aimed at tackling the challenges presented by physical systems. We believe this focus on real-world application will bring together a cross-section of researchers working on different areas of research for a fruitful exchange of ideas including our invited speakers.

Useful Models for Robot Learning
Abstract: In robot learning we face challenge of data-efficient learning. In this talk, we will make the case for three types of useful models that become handy in robot learning: probabilistic models, hierarchical models, and models that allow us to incorporate the underlying physics. We will briefly outline strong use cases for these three models in the context of model-based reinforcement learning, meta learning, and system identification.

Toward Topic Models of Robotic Manipulation and the JengaBot
Abstract: Hierarchical representations are a promising tool for robotic manipulation tasks. In this talk, we present a two-step approach to learning a class of hierarchical predictive models with application to physics modeling and robotic manipulation. These models facilitate learning spatio-temporal abstractions over physics and are amenable to probabilistic inference, controls, and planning. To build intuition for the learned abstractions, we provide an analogy between these models and their natural language processing counter-parts. Further, we show how these models can be used for sample-efficient controls. We end with a discussion on when we expect these approaches to not work well.

Finding the Right Balance of Modelling and Learning for Vision-based Robot Manipulation
Abstract: In recent years, a wide range of learning-based approaches have been developed for robot control. However, classical robot control, using model-based approaches, has significant potential which has often been overlooked, due to the popularity of end-to-end systems. With a specific focus on vision-based robot manipulation, I will argue that finding the right balance of these two ideologies presents our best chance of making the first real breakthroughs for robotics in unstructured environments.

How should we design a robot learning system?
Abstract: When we develop a robot learning system, we have to consider many design choices. In this talk, I will share some of my experiences with industrial partners and discuss problems in the design of a robot learning system.

Machine Learning for Mobile Robots: Safety, Data Efficiency, and Fast Adaptation
Abstract: The ultimate promise of robotics is to design devices that can physically interact with the world. To date, robots have been primarily deployed in highly structured and predictable environments. However, we envision the next generation of robots (ranging from self-driving and -flying vehicles to robot assistants) to operate in unpredictable and generally unknown environments alongside humans. This challenges current robot algorithms, which have been largely based on a-priori knowledge about the system and its environment. While research has shown that robots are able to learn new skills from experience and adapt to unknown situations, these results have been mostly limited to learning single tasks, and demonstrated in simulation or structured lab settings. The next challenge is to enable robot learning in real-world application scenarios. This will require versatile, data-efficient and online learning algorithms that guarantee safety when placed in a closed-loop system architecture. It will also require to answer the fundamental question of how to design learning architectures for dynamic and interactive agents. This talk will highlight our recent progress in combining learning methods with formal results from control theory. By combining models with data, our algorithms achieve adaptation to changing conditions during long-term operation, data-efficient multi-robot, multi-task transfer learning, and safe reinforcement learning. We demonstrate our algorithms in vision-based off-road driving and drone flight experiments, as well as on mobile manipulators.
