Compact Hexapod 6-Axis Stage: Higher Performance for Precision Alignment

POSTED 06/20/2018

Hexapod 6-Axis Stages are useful in Alignment of Optics, Precision Components, in Aerospace.

Auburn, MA – PI has added a higher performance model to its range of compact hexapods. The New H-811.i2 provides twice the velocity along with sensor resolution up to 8 times higher compared to the current H-811.D2 miniature hexapod.  The compact size, robust design with low friction ballscrews brushless motors, and powerful controller with multi-axis alignment capabilities make the new hexapod an ideal tool for high duty cycle alignment applications in optics, automotive and photonics applications.

How do Hexapod Parallel Motion Systems work?

Hexapods 6-Axis Stages are 6-DOF positioning / motion systems that derive 6-axis movement (XYZ, pitch, yaw, roll) from actuators placed in parallel between a top and bottom platform.  Available in a variety of sizes with bases ranging from 50mm to 1m and different load capabilities up to 2 tons, PI hexapods are an easy solution to complex multi-axis precision motion applications. PI hexapods come with state-of-the-art controllers and software tools based on 25 years of hexapod R&D, resulting in fast solution implementation to a plethora of applications from medical to photonics. All 6 axes can be commanded simply as Cartesian coordinates, and the center of rotation can be changed on the fly with a software command. Other advantages are the absence of friction and torque, caused by dragged cables.
