A flexible multi-sensor positioning system for industrial robots

This paper offers an approach for a sensor-based robot positioning system which solves the problem of positioning the tool of an industrial robot relative to a work object for a subsequent assembly or application in the same way as it was done once during setup with a reference work object. The approach takes sensors as abstract data sources and is therefore able to use different kinds of sensors at the same time to fulfill its task. The proposed solution focuses on a flexible system that suits the needs of the industry in respect of good maintainability, good robustness and high accuracy.
