Brochure: Hexapod Six-Axis Precision Parallel Kinematics Systems
(Nanowerk News) 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: o Programmable Pivot Point for Simple Rotational Alignment Tasks o Lower Inertia and Higher Stiffness o Better Dynamic Behavior o Smaller Package Size o No Accumulation of Position Errors, Reduced Runout Errors o 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: o Optics & Photonics, Telecommunication o Astronomy / Aerospace o Biotechnology o Semiconductor Test & Handling o Microscopy
