Abstract
Manipulator dynamics tells us how the manipulator responds to joint torques and external forces. Each joint is normally equipped with an actuator which generates either linear forces or torques in the direction or around a fixed axis. The relatively simple joint torques and forces applied at each joint result in a complex overall motion of the robotic manipulator. One of the most important questions in robotics is thus how to find the joint torques that give the desired robot motion.
In this chapter we present the dynamic equations of a robotic manipulator in a well-defined but simple way. The chapter can be used in an introductory course to robotics and will give the reader a good understanding of how to model manipulator arms. Furthermore, as the formulation is based on the mathematically rigid formulations presented in the previous chapters, this chapter may also be interesting for readers already familiar with robotics and would like a mathematically more robust treatment than the one normally found in textbooks on robotics.
