The overarching goal of this class is to provide students with an overview of the current state of the art in the field of dynamics and control of legged (robotic) systems. Subtopics range from basic biomechanics and locomotion in nature to optimal control of robotic systems. To this end, the course will apply the principles of mechanical dynamics to a specific class of systems and will hence cover a broad range of dynamics topics, including multibody-dynamics, non-smooth dynamics, nonlinear-dynamics, limit cycles, continuation, and bifurcation, as well as a range of different control strategies. For students, this will provide a unique opportunity to experience how their theoretical dynamics knowledge can be put into practice. A series of hands-on programming exercises and a robotic locomotion competition will round off the class content.
