Abstract:
Human bipedal locomotion involves complex underlying dynamics. Perturbations during walking, such as slips or trips, require rapid whole-body adjustments and significantly increase task complexity. Capturing these movements and designing devices to assist during such perturbations presents a challenge. Successful design and implementation of such devices requires understanding of human motion dynamics, balance stability and human-machine interactions.

In this talk, I will present sensing, modeling and control approaches for characterization of human walking with foot slip. I will demonstrate that the combination of modeling and sensing of shoe-floor interactions can be used to predict foot slip using a soft-solid contact model. Development of a robotic bipedal model and control for analyzing human balance stability during slip perturbation will be presented. This approach will be extended to describe the development of a rapid foot slip detection system and the development of a robotic assistive device to prevent slip-induced falls. These approaches and systems have applications in the field of biomedical engineering, rehabilitation and soft robotics. I will conclude with a brief presentation of my future research direction.
