Accuracy enhancement for robotic systems

Zero-defects, top-quality production results can only be achieved if all system components interact precisely. Furthermore, in order to carry out targeted manipulation using industrial robots, the exact position of components in the robot cell must be known. Especially the position of tools and sensors located at the robot's end effector needs to be accurately identified in order to move the tool on a defined path and execute the process as accurately as possible.

Time and again, however, processes fail to meet these high accuracy requirements. Experience shows that these reliability problems are due to the fact that the robot cell is not calibrated accurately. Fraunhofer IPA offers tailor-made solutions for this. With our state-of-the-art measuring systems and robotics expertise, we pinpoint sources of error and help you optimize your equipment. In addition, our expert knowledge combined with our first-class facilities enables you to calibrate your robot components with a high degree of accuracy, thus improving the reliability and quality of your processes. We would be pleased to advise you on site or in our research laboratories.

Measuring industrial robots to increase accuracy

Measuring a robot system helps make it more efficient and makes it possible to predict the quality of task execution. Prior knowledge of what will happen if the application changes enables industrial robots to be used more flexibly.
