1

Welcome to the discussion category for Chapter 2: Rigid Body Motion on Lie Group.

This chapter applies Lie group theory to describe rigid body kinematics and dynamics in 3D space. Major topics include:

  • Homogeneous transformations and adjoint operators
  • Representing velocity and acceleration with twists
  • Body-frame wrenches and inertial parameters
  • Equations of motion for single rigid bodies using SE(3)

These tools provide a structured and coordinate-free way to model rigid body mechanics in robotics.
