Correcting Regions of Inaccurate Modeling for Online Performance Improvement
Event Location: NSH 3002Abstract: To make intelligent decisions, robots often use models of the effects of their actions on the world. Unfortunately, in complex environments, it is often infeasible to create models that are accurate in every plausible situation, which can lead to suboptimal performance. In these cases, online correction of model inaccuracies can lead [...]

Handheld Micromanipulator for Robot-Assisted Microsurgery
Event Location: NSH 3305Abstract: Robot-assisted surgery has been increasingly adopted in a wide variety of surgical applications because it offers fine manipulation with high precision and dexterity. Despite the commercial success of robotic platforms, practical use in microsurgery is still challenging due to a considerable level of accuracy required at sub-millimeter scales. Limited visualization and [...]

Forecasting Human Motion in Social Situations
Event Location: NSH 1507Abstract: The goal of this thesis is to further our understanding of nonverbal communication by developing methods and representations to quantify and predict human body motion during social interactions. We design a data collection protocol and capture system to obtain 3D body pose and facial annotations for groups of interacting people engaged [...]
Modeling Closed-Loop Adaptive Systems
Event Location: NSH 1305Abstract: Brain-machine interfaces (BMIs) are a powerful class of assistive devices that may one day restore movement ability to paralyzed individuals. These devices act by creating a direct mapping between recorded neural activity and the movement of an external actuator, like a computer cursor or a robotic arm, bypassing defective neural transmission [...]
