AUBURN, Mass., July 25, 2012 — PI (Physik Instrumente) L.P. provides a complete line of six-axis robotic parallel positioners (Hexapod/SpaceFAB) for applications in bio/nanotechnology, aerospace, medical technology and lasers/photonics.
Hexapod parallel positioners differ from articulated/stacked multiaxis positioners, where each actuator is connected to the other actuators/motion axes in a serial configuration. In a hexapod positioner, all six actuators work together, affecting the common motion output platform. This design increases stiffness while reducing size and moving mass.
The control of submicron- or nanometer-precise motion patterns in 6-D space requires advanced motion controllers and algorithms. PI’s dedicated 6-D vector hexapod controllers are bundled with software for programming and simulation of complex movements. Ethernet connectivity for remote servicing and remote control with an iPad app are standard.
With the acquisition of precision motion control specialist miCos GmbH, another parallel robotic concept called SpaceFAB is also available from PI. SpaceFAB positioners combine the motion of three two-axis planar positioners into one low-profile six degrees-of-freedom motion system.
Hexapods provide high precision in the submicrometer to nanometer realm. Applications include medical engineering (computer-aided surgery, tumor radiation treatment); telecommunications (alignment of fibers and fiber optic chips); laser machining; semiconductor test and metrology (positioning/alignment of substrates, lasers); particle physics (high-energy experiments in accelerator rings); x-ray microscopy; and crystallography.
