Precision through an Intelligent Robot Model
ISIOS creates a high-precision mathematical model of the entire robot, taking into account not only geometric deviations, but also elasticity, load-induced deformation, joint errors and tool and orientation errors. On this basis, all relevant influences are continuously compensated.
For applications with particularly demanding accuracy requirements, ISIOS real-time compensation enables the highest absolute accuracy.
Patented Laser Sensor Technology for the Highest Absolute Accuracy
The ISIOS Laser Sensor System uses the inherent precision of a laser beam as a highly accurate reference for determining even the smallest robot deviations. Even minimal position and orientation errors are reliably detected and incorporated into the precise robot model.
Unlike conventional calibration methods, the system operates without an expensive laser tracker and enables the highest absolute accuracy throughout the entire workspace. The result is reproducible manufacturing processes, reduced measurement effort and a cost-effective solution for demanding industrial applications.
Our recalibration systems enable regular, automated verification and correction of the absolute accuracy of industrial robots directly in the production facility. ISIOS handles the complete design, configuration and commissioning, individually tailored to the robot, the tools used and the specific requirements of each installation.
ISIOS Tracker Guidance (TRG) increases the accuracy of industrial robots beyond the capabilities of conventional robot calibration. During operation, a laser tracker continuously measures the actual robot pose. The measured pose deviations are used directly to correct the robot pose in every interpolation cycle. The result is absolute accuracy in the range of a few hundredths of a millimetre on very large components over distances of 40 metres and more, while moving and in real time.
