Content:

Simulations of human gait have many potential uses, for example to help understand human motion and to speed up design of assistive devices such as prostheses and exoskeletons. Human gait simulations are created by solving trajectory optimization problems, using concepts from optimal control. In this seminar, the aim is to become familiar with different approaches that are used to solve trajectory optimization problems related to human motion simulations. Different methods will be introduced and compared. Students will study a state-of-the-art paper and present the details of the problem described in the paper.
