3SAE PentaPod® Multi-Axis Positioner

Features

• Uses unique, patented, 5-degree of freedom joints that facilitate sub-micron precision motion in 5 or 6 axes.
• Offers a simple system integration with a single USB connection and no external controller required.
• Parallel Kinematic design providing exceptional positioning accuracy and stiffness.
• Software adjustable point of rotation.
• Small size and low profile without compromising on stroke, precision, or crosstalk.
• A fraction of the cost and complexity of a comparable Hexapod.

Introduction

The PentaPod®, developed by 3SAE, is a groundbreaking Kinematic Multi-Axis Micro Positioning Stage that combines the advantages of both Parallel (Hexapod) and Serial stages. With an impressive 5/6 Degrees of Freedom (DOF), this innovative design represents a significant leap forward in precision positioning technology.

Unparalleled Performance and Versatility

The PentaPod®'s patented "parallel kinematic design" delivers exceptional positional stiffness in the X and Z axes, while minimizing crosstalk across all axes. Its performance is remarkable, with the X and Z axes boasting a travel range exceeding 9mm and a measured resolution finer than 81nm. The XΘ and YΘ axes provide a 17° travel range, while the ZΘ axis offers 8°, all with a measured resolution better than 2.55µrad.

Singularity-Free Design

One of the key advantages of the PentaPod® over traditional Stewart Platforms (Hexapods) is its singularity-free design. This unique feature ensures that the stage can achieve any position within its operational range without the risk of binding due to kinematic constraints.

Streamlined and Compact

The PentaPod®'s compact design is further enhanced by the integration of all control electronics within the stage platform itself. This streamlined approach eliminates the need for bulky, external, multi-core controllers typically required to manage positional singularities and prevent stage binding in Stewart Platforms.
Today, the PentaPod® offers unparalleled performance and versatility in a compact, efficient package and represents a significant advancement in precision positioning technology.
