Abstract

Forward dynamics of general articulated rigid bodies has been an active research area for long, and a number of algorithms have been developed over the years. While most of these algorithms can be applied to humanoid robots, there are some unique features that make some algorithms more preferable than others. For example, humanoid robots usually have tens of joints, and, therefore, the numerical complexity of an algorithm becomes more important. Humanoid robots often form complex closed kinematic chains by grasping an object or getting in contact with the environment. The forward dynamics algorithm should be able to handle these situations efficiently.

This chapter reviews some of the forward dynamics algorithms often used for humanoid robot and character simulation. Readers are referred to chapter “Dynamic Formulations and Computational Algorithms” for inverse dynamics algorithms used for analyzing joint torques and chapter “Contact Simulation” for contact force computation.
