Product Lineup
6-Axis Hexapods / Parallel Positioners
Hexapod 6-axis parallel positioners are often referred to as Stewart Platforms. A hexapod is based on a 6-axis (XYZ, Pitch, Roll, Yaw) actuator system arranged in parallel between a top and bottom platform. PI’s parallel kinematics (PKM) precision positioning systems have many advantages over conventional serial kinematics stages, including lower inertia, improved dynamics, smaller package size and higher stiffness.

Gantries
A precision gantry stage or gantry system is sometimes called a linear robot or Cartesian robot. Gantry robots typically provide overhead motion in 2 or 3 linear degrees of freedom (X-Y and X-Y-Z) and are often used for pick and place applications, 3D printing or laser machining, precision handling, and electronics applications. These precision automation systems only share the name and general layout with the high load gantry cranes often used in ports for loading and unloading of cargo.
Motorized Stages
PI offers the broadest and deepest range of precision motion technologies for micro and nano precision applications. Our engineers work with our customers to find the best drive and bearing technology for each individual application. Having access to multiple drive and positioning technologies allows an open discussion with a better outcome for the customer.

Linear Actuators
A precision linear actuator is a positioning device that provides motion in 1 degree of freedom. PI designs and manufactures a variety of precision linear actuators (pushers) including economical stepper-motor driven actuators, high-speed linear motor types for automation and nanometer precise piezo-motor actuators.

Piezo Transducers & Actuators
Piezoelectric translators (transducers) are precision ceramic actuators which convert electrical energy directly into linear motion with high speed, force and virtually unlimited resolution. These actuators are used in every modern high tech field from semiconductor test & inspection to super-resolution microscopy, bio-nanotechnology and astronomy/aerospace technology.

Controllers & Drivers
The performance and usability of a precision positioning system depends on the mechanics, motion control electronics, and software. PI offers dedicated controllers for traditional piezo actuated nano-positioning systems, as well as motorized positioning systems based on linear motors, brushless motors, servo motors, and stepper motors.
