"TīmeklisStarting in Chapter 8.2, we learn the Newton-Euler method for deriving the dynamics of a robot. Whereas the Lagrangian formulation starts with the potential and kinetic energy and applies a variational approach based on derivatives, the Newton-Euler method is derived directly from f equals m-a for the rigid bodies that make up the robot.

TīmeklisLagrangian mechanics—which has the added appeal of intrinsically combining the Hamiltonian point of view on T⁄Q and the Lagrangian perspective on TQ—is the so-called Hamilton–Pontryagin principle, whose variational structure was studied by Yoshimura and Marsden (2006). Rather than extremizing the action over paths The following examples apply Lagrange's equations of the second kind to mechanical problems.
