New Brochure: Hexapod Six-Axis Precision Parallel Kinematics Systems, Positioners & Robots Featuring Sub-Micron Resolution from PI Sep 12, 2007

PI (Physik Instrumente) L.P. -- a leading manufacturer of precision sensors and motion-control equipment for optics / photonics, nano / biotechnology, semiconductor and life science applications -- offers a new brochure on Hexapod 6-Axis Parallel Kinematics Robots and Positioning Systems.

The Hexapod system, (also known as Stewart Platform), which is supplied with a special motion controller, has unique features when compared to a stacked series of stages.

Advantages of Parallel Kinematics (PKM) Systems over
standard (stacked) Serial Kinematics Stages:

• Programmable Pivot Point for Simple Rotational Alignment Tasks<.li>
  
• Lower Inertia and Higher Stiffness
• Better Dynamic Behavior
• Smaller Package Size
• No Accumulation of Position Errors, Reduced Runout Errors
• No Moving Cables for Better Repeatability and Reliability

The brochure presents a variety of standard and custom hexapod systems, featuring sub-micrometer resolution, and load capacities from 2 kg to 1000 kg.

PI has been designing and manufacturing hexapod positioning robots since the early 1990’s. Today, standard hexapod designs come in all shapes and sizes and include servo motor-driven systems for moving large optics up to 1 m diameter to piezo based designs for nanometer precise control of semiconductor wafers and masks. Standard and custom systems are available in non-magnetic and vacuum compatible versions.

These parallel motion systems are designed for applications in fields such as:

• Optics & Photonics, Telecommunication
• Astronomy / Aerospace
• Biotechnology
• Semiconductor Test & Handling
• Microscopy
