Lecture
This lecture covers the concept of inverse dynamics, focusing on the ankle joint. It explains how to calculate net joint forces and moments, mechanical work, and power produced at joints. The instructor demonstrates the application of inverse dynamics in robotics and determining the torque required for specific motions. Through examples, the lecture illustrates the use of anthropometric and kinematic parameters, as well as force plates, to analyze the ankle joint. It also discusses the calculation of net forces and moments at the knee and hip joints by using the ankle as a reference. The presentation emphasizes the importance of understanding joint reactions and their implications in biomechanics.
