Conservative to confident: Treating uncertainty robustly within Learning-Based Control

ICRA 2015poster

Robust control maintains stability and performance for a fixed amount of model uncertainty but can be conservative since the model is not updated online. Learning-based control, on the other hand, uses data to improve the model over time but is not typically guaranteed to be robust throughout the pr…

It's not easy seeing green: Lighting-resistant stereo Visual Teach & Repeat using color-constant images

ICRA 2015poster

Stereo Visual Teach & Repeat (VT&R) is a system for long-range, autonomous route following in unstructured 3D environments. As this system relies on a passive sensor to localize, it is highly susceptible to changes in lighting conditions. Recent work in the optics community has provided a method to…
