Recursive multibody dynamics and discrete-time optimal control [PDF]
A recursive algorithm is developed for the solution of the simulation dynamics problem for a chain of rigid bodies. Arbitrary joint constraints are permitted, that is, joints may allow translational and/or rotational degrees of freedom.

Dynamics and Control of Multibody Systems
, 2010 Physics-based simulation has emerged as a popular approach for realistic animation and analysis of rigid and articulated bodies in motion. This chapter briefly reviewed basic principles of unconstrained rigid body mechanics and then focused on the more challenging constrained rigid body mechanics principles. We have outlined basic concepts of rigid and
