PI Intros Smallest 6-Axis Micropositioner
6-axis positioning system.
Auburn, MA, — Physik Instrumente has introduced the world's smallest commercially available electro-mechanical, high-force Hexapod 6-axis micropositioning system. Called the M-810, the Miniature Hexapod micropositioning system has high-force 6-Axis hexapod with 5kg load capacity.

It is compact in size, with a 10cm diameter, and is 11.8cm high. According to the company, it provides sub-micron resolution; long travel ranges to 40mm (linear) and 60° rotation; its powerful controller has freely definable virtual pivot point; high velocity of 10mm/s; operation in any orientation; and linear and rotary multi-axis scans.

Parallel-kinematic motion systems have a number of advantages over standard serial kinematic (stacked) positioning systems: only one moving platform, no accumulation of guiding and lever-arm errors; no moving cables for improved reliability and precision; smaller package size; increased stiffness, reduced inertia, better dynamics; and virtual pivot point.

Limited space necessitates new technologies for encoders, motors and other integrated electronic components. Nevertheless, the M-810 is compatible with the company's proven hexapod controllers that are supported by windows software and a library of drivers and programming examples for applications such as optical alignment.
