September 5, 2007 - PI (Physik Instrumente) 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.
The brochure presents a variety of standard and custom hexapod systems, featuring sub-micrometer resolution, and load capacities from 2 kg to 1000 kg.
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
Advantages of Parallel Kinematics (PKM) Systems over standard (stacked) Serial Kinematics Stages:
Programmable Pivot Point for Simple Rotational Alignment Tasks
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
