Robotic Nano Positioning Systems from PI
Robotic nano-positioning platforms.
Auburn, MA — PI (Physik Instrumente) LP provides a complete line of highly accurate 6-axis robotic parallel positioners (Hexapod/SpaceFAB) for advanced applications in fields as diverse as bio/nano-technology, aerospace, medical technology and lasers/photonics.
Hexapod parallel positioners differ from classical
articulated/stacked multi-axis positioners where each actuator is connected to the other actuators/motion axes in a serial configuration. In a hexapod positioner, all six actuators always work together affecting the common motion output platform. This design principle increases the stiffness while reducing the size and the moving mass significantly.
With the acquisition of precision motion control specialist miCos GmbH, another parallel robotic concept called SpaceFAB is now also available from PI. SpaceFAB positioners combine the motion of three 2-axis planar positioners into one low-profile 6 degrees-of-freedom motion system.
While originally designed for an automotive tire testing machine, today's Hexapods/SpaceFABs now provide an unprecedented level of precision in the sub-micrometer to nanometer realm. Applications are found in all technology fields: 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); astronomy (mirror alignment in large earthbound telescopes); X-ray microscopy and crystallography.
PI is the leading manufacturer of precision micropositioning and nanopositioning hexapods. The company introduced its first sub-micrometer precision hexapod two decades ago and today provides a large variety of different models with load capacities from 2 kg to several tons, featuring units as small as a palm top.
The control of sub-micron or nanometer-precise motion patterns in 6-D space requires advanced motion controllers and algorithms. PI Hexapod robotic positioners come with a choice of dedicated 6D vector controllers and bundled with software for programming and simulation of complex movements. Ethernet connectivity for remote servicing and remote control with an iPad app are standard.
