How can the advantages of hexapods be easily used in automation processes? A new whitepaper from PI (Physik Instrumente) explains how the integration of the hexapod controller with an EtherCAT® interface works.

Manufacturing and quality assurance processes in electronics production, mechanical engineering, and the automotive industry increasingly require multi-axis positioning systems. At the same time, the requirements for accuracy are also increasing. Because of their design, parallel-kinematic hexapod robots can move and position tools, workpieces, and complex components with weights ranging from a few grams to several hundred kilograms or even several tons in any spatial orientation with high precision – regardless of the assembly orientation.
Complex Kinematic Easily Integrated: Multi-Axis Drive with Fieldbus Connection
In a parallel-kinematic system, the motor axes do not correspond to the Cartesian axes. Therefore, a computation-intensive coordinate transformation is necessary for each new position. The digital hexapod controller carries out the computation and, thanks to the integrated EtherCAT® interface, hexapods can easily be integrated in the higher-level control system.
By using standardized real-time Ethernet protocols and moving the transformation calculations to the hexapod controller, the user is not dependent on a specific control manufacturer.

This new whitepaper explains
- how the integration works,
- how Work and Tool coordinate systems can be used, and
- how the range of motion of the hexapod can optimally be used.
