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.
Hexapod 6-Axis Parallel Kinematics Systems Brochure
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
- 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
