This module covers payload, accuracy, repeatability and resolution in modern industrial robotics. The student will learn to apply compliance parameters to determine overall performance and explain the various factors affecting the accuracy of a robot. The module also covers position error and describes common calibration techniques used in robot installation and maintenance. In addition to the basics of kinematic coupling, the module also presents standard performance characteristics noted in ISO9283. The principles of spatial resolution and compliance are discussed with an emphasis on practical applications and troubleshooting techniques.
