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 ReliabilityAbout PI PI is the industry leader in ultra-precision motion control devices for nanoscale manufacturing, test and research applications.
