Abstract:
Robotics benefits heavily from structure. By exploiting that structure, such as by modeling the mechanics of a system, roboticists can quickly generate solutions for a given task. However, this structure can limit flexibility and require practitioners to reason about challenging phenomena, such as contacts in mechanics. Data, on the other hand, provides much more flexibility and, when combined with deep neural networks, has given rise to powerful models in vision and language, all with little hand-engineered structure involved. While it is tempting to fully eschew structure in favor of learning-based methods for robotics, we show how data and learning can be gracefully incorporated in a structured way. In particular, we focus on the control setting, and we demonstrate that robotic control offers a variety of modes that data can be utilized. This includes: modeling off-road vehicles with neural networks for aggressive driving, framing model predictive control as an online learning process, using safety interventions as a learning signal, and leveraging human motions to ground learned robot motions.
