Comparison of Dynamic Properties of Two LWR 4+ Robots

Łukasz Woliński , Marek Wojtyra


An efficient dynamic model of LWR4+ robot, based on a recursive multibody approach, is presented. For a test trajectory, driving torques in joints are calculated and measured directly on two different robots of the same type. The repeatability of each robot performance is verified. The calculated and measured quantities are compared. The accuracy of model as well as the variability of robots dynamic parameters are assessed. The obtained results are discussed in the context of individual robots identification.
