Biped Motion Planning and Human Movement Biomechanics: Predictive Modeling

Assistant Professor; Departments of Mechanical; University of Alaska, Fairbanks


This seminar will focus on predictive modeling for biped motion planning and human movement biomechanics. The predictive modeling is essentially an optimal control approach applied to the motion planning problems. It has two major applications: biped motion planning and human movement biomechanics. Biped motion planning focuses on controls for the planned motion. Instead, human movement biomechanics emphasize muscle and joint forces. A novel inverse-dynamics-based optimization method is introduced for predictive modeling. This method has real-time simulation capability which makes it superior than other approaches in the literature. First, it is demonstrated for biped motion planning with walking, lifting, stair climbing, and box delivering tasks. Next, it is used to study human movement biomechanics to predict muscle forces. With this superior motion prediction capability, the developed predictive modeling method has wide applications in injury risk prediction, assistive robot design, medical device design, and human-robot collaboration planning.
