Unformatted text preview: Lecture 6 Introduction to Simulation Lab 1 EML 5595 Mechanics of the Human Locomotor System Outline Comments on Pandy et al. (1990) Installation of Simulation Lab 1 Goals of Simulation Lab 1 Optimal Control of Jumping Question: Theoretically, how should leg muscle forces be coordinated to produce a maximum height jump? Answer: Look in Pandy et al. (1990). Optimal Control of Jumping
Question: Why did Pandy et al. (1990) choose jumping as their first dynamic optimization problem to address? Answer: Two main reasons. First, the cost , function is unambiguous and does not require making assumptions about what is optimal from a physiological p p p y g perspective. Second, the body moves in a symmetric manner, which simplified the modeling. Jumping Model Question: What do you think of this musculoskeletal model?
