Self-Supervising Occlusions for Vision
Abstract: Virtually every scene has occlusions.

More complex occlusions occur when one or more objects block part(s) of [...]

Audience-Aware Legibility for Social Navigation
Abstract: Robots often need to communicate their goals to humans when navigating in a shared space to assist observers in anticipating the robot’s future actions. These human observers are often scattered throughout the environment, and each observer only has a partial view of the robot and its movements. A path that non-verbally communicates with multiple [...]

Learning via Visual-Tactile Interaction
Abstract: Humans learn by interacting with their surroundings using all of their senses.
