An automated quick accuracy and output signal check for industrial robots

Abstract

Due to the increasing complexity of application of industrial robots the demand of higher robot accuracy is an important part of modern robotics. This accuracy is needed in offline programming, copying programs or image-processing. The identification of the actual accuracy of one robot and the comparison with the manufacturer informations is in some cases decisive for the purchase. Therefore a quick solution for an accuracy check of an industrial robot is needed to assure the denoted manufacturer values. This paper illustrates a new developed quick accuracy check according to the european standard EN ISO 9283 and a separate quick signal check of industrial robots, modified by the needs of the customer. After measuring the robot with an external measurement system the data is analysed by a special automated software module, which creates presentation-ready documents with a minimum of user interaction.
