Hexapod / SpaceFAB Parallel Precision Robotic Positioning Systems from PI

Auburn, MA, PI (Physik Instrumente) LP – a leading manufacturer of motion control systems for nano-automation — 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. Parallel Robots: How do they Work? Hexapod parallel positioners differ from classical articulated / stacked multi-axis positioners where each actuator is connected to the other actuators / motion axes

Ceramic Drivers for Higher Precision

Piezo stepping drives replace the usual stepper or DC motors in the linear actuators of the N-381 series from Physik Instrumente (PI). As a direct linear drive the stepping drive is free of precision losses due to the exchange from rotational to linear motion. The N-381 can be operated at a velocity of 10 mm/s, provides resolutions of 20 nanometers, the position is measured using an integrated linear encoder. The
