PI (Physik Instrumente) LP - a leading manufacturer of motion control systems for nano-automation - introduces its new H-Series of Hexapod robitic positioners and 6-Axis motion Controllers.

Auburn, MA July 18, 2012

In addition to the new Hexapod parallel positioners, PI is now also in a position to offer SpaceFAB six-axis positioners. SpaceFABs combine the motion of three 2-axis planar positioners into one low-profile 6 degree-of-freedom motion system. With the recent acquisition of precision motion control specialist miCos GmbH, PI can now provide more than 20 different parallel-kinematic positioning systems

Parallel Robots: How do they Work?
Hexapod parallel positioners differ from classical articulated / stacked multi-axis positioners where each actuator is connected to the other actuators / motion axes in a serial configuration. In a hexapod positioner, all six actuators always work together affecting the common motion output platform. This design principle increases the stiffness while reducing the size and the moving mass significantly.

Highly Sophisticated Hexapod Controllers, Software, Remote Control through iPad
The control of sub-micron or nanometer-precise motion patterns in 6-D space requires advanced motion controllers and algorithms. PI Hexapod robotic positioners come with a choice of dedicated 6D vector controllers and bundled with software for programming and simulation of complex movements. Ethernet connectivity for remote servicing and remote control with an iPad app are standard.

Hexapod Applications
While originally designed for an automotive tire testing machine, modern hexapods have come a long way and provide unprecedented precision in the sub-micrometer to nanometer realm. Applications are found in all technology fields: medical engineering (computer aided surgery, tumor radiation treatment); telecommunication (alignment of fibers and fiber-optic chips); laser machining; semiconductor test & metrology (positioning / alignment substrates, lasers); particle physics (high-energy experiments in accelerator rings); astronomy (mirror alignment in large earthbound telescopes); X-ray microscopy and crystallography, etc.

Large Variety of Sizes and Configurations
PI is the leading manufacturer of precision micropositioning and nanopositioning hexapods. The company introduced its first sub-micrometer precision hexapod two decades ago and today provides a large variety of different models with load capacities from 2 kg to several tons, featuring units as small as a palm top.
