Hexapod Enables Highly Dynamic 6-D Compensation Kinematic for Robots

· Stefan Vorndran

Physik Instrumente developed a high-performance 6-DOF hexapod motion and positioning system for highly dynamic compensation kinematics in aircraft construction. The project's goal was to enhance the processing and sealing precision of CFRP-components in resin transfer molding manufacturing processes, while also reducing manufacturing times and process costs.

What is the Difference between a Piezo Actuator and a Programmable Piezo Shim?

New Tools for Design Engineers of Optics and Precision Mechanical Systems

· Stefan Vorndran

PIRest is a new and unique piezo technology, where the actuator keeps its expansion without a permanently applied voltage. This leads to a simple set-and-forget alignment method without limitation of the lifetime of the actuator.
