    8/23/2017

    When controlling motion at the sub-micrometer or nanometer levels for alignment and handling applications, it is imperative to have high reliability, robustness, minimized latency, and high-speed synchronization with external devices to reach sub-micrometer path accuracy. The higher the dynamics and throughput targets of a multi-axis precision motion system, the more holistic the design approach must be in order to achieve success. A systems approach where the mechanics, control electronics, and software are designed by the same team provides a great amount of benefits for the user.

  9. Hexapod For Beamline Instrumentation Combines 6-Degrees Of Freedom With Extreme Accuracy And Repeatability
    12/15/2016

    Within synchrotron-based, sub-micrometer, hard X-ray tomography applications, the sample rotation axis must be aligned with high stability and within five degrees of freedom with respect to its field of view, lens, detector, or the beam itself. A hexapod-type parallel kinematic machine (PKM) is able to provide six degrees of freedom, an arbitrary pivot point option, and a compact, stiff design that is well suited for this purpose. This blog article discusses a tomography application challenge and how a hexapod positioning system is used to provide the solution.
