Software, Programming and Controller

Like all PI parallel kinematic Hexapod positioners, the miniature vacuum Hexapod comes bundled with software and a highly specialized digital controller with high-speed Ethernet connectivity. Programming and commanding the Hexapod is simple and straight-forward, as all positions are conveniently given in Cartesian coordinates (XYZ, Theta X, Theta Y, Theta Z).

Parallel Kinematics vs Conventional Serial Kinematics Parallel-kinematics positioning systems have several advantages over conventional stacked multi-axis positioners. All six actuators directly affect one common platform, significantly reducing mass and inertia. Moreover, there is no accumulation of the lateral and angular runout errors of the individual axes. Unlike rotation stages and goniometers which come with a fixed center of rotation, the PI Hexapod concept lets the user set and change the pivot any time via software.

Hexapod Applications, Range Today, hexapod applications are found in all technology fields: high-energy physics, medical engineering, X-ray microscopy, photonics alignment, semiconductor test & metrology, astronomy, precision machining, aeronautics, etc. PI is the leading manufacturer of precision micropositioning and nanopositioning hexapods. The company introduced its first hexapod 2 decades ago for a precision alignment system in an astronomical telescope and provides a large variety of different models with load capacity from 2 kg to more than 2,000 kg.
