Abstract

Robot manipulators have greatly enhanced the performance of automated processes during the last decades. Industrial competition, however, creates an increasing demand to further improve the accuracy of off-line programming. Validated dynamic robot models are required for this purpose. We describe the development of a generic dynamic model which include centrifugal, gravitational and Coriolis forces, motor dynamics, joint elasticities, etc. and specialize it to an actual industrial robot KUKA IR 761. The time-optimal control is used in our computations for the rigid model of the manipulator performing a real life transport maneuver. The compliant vibrations of overall robot model exhibited by time-optimal piecewise control are analyzed.
