PI introduces the new H-860 high-speed hexapod system designed to accurately simulate motion with six degrees of freedom. The platform features high accuracy and bandwidth that optimizes motion and image stabilization algorithms that are used in drones and cameras, and for pinpoint accurate images. Ideal applications include vibration simulation, precision positioning, lens alignment in camera manufacturing, photonic fiber alignment, and image stabilization.
The new S-255 piezo fast steering mirror (FSM) from PI is designed with millisecond response settling time, high dynamic linearity for precision image processing and image stabilization, laser beam steering, materials processing, and lithography. These piezo steering mirrors are based on parallel-kinematic designs with coplanar rotational axes and a single moving platform driven by two pairs of differential actuators that enables jitter-free, multi axis motion with excellent temperature stability.
PI offers the V-408 PIMag® Linear Motor Stage with magnetic direct drive and an incremental linear encoder for direct position measurement, high-force 3-phase linear motor drives, and general automation applications. With high load capacity precision crossed roller elements and an anti-creep cage assist prevents roller creep, offers zero-wear, and makes the device capable of long life in high duty cycle industrial applications.
PI offers the new A-60x MTT, a X-Y-Tip-Tilt positioning stage, featuring PIglide rotary air bearing stages and platforms with completely frictionless, non- contact motion, and velocity stability, making the stage ideal for high-end industrial inspection and manufacturing operations. With manual adjustment capabilities from the X-Y-tip-tilt rotary air bearings, the stage is able to provide the perfect alignment of a payload to the bearing’s axis of rotation.

Ideal applications for this stage include micro-assembly, biotechnology, precision laser machining, optics, lens testing, and photonics alignment.
The U-780 from PI is a new low-profile precision positioning stage with a controller and joystick for high-resolution microscopy applications. With technology based on PI’s patented ultrasonic ceramic linear motors, this motorized stage provides extremely high stability, which is vital for high-resolution imaging.
The P-736 PInano®-Z is a low profile, low cost, high-speed piezo-Z slide scanner with extremely fast step and settling times from 5 msec at target position. With an exceptionally low profile for easy integration and travel ranges of 100 or 200 µm, this scanner is ideally used for scanning microscopy, 3D imaging, laser technology, interferometry, metrology, biotechnology, and micromanipulation.
PI offers the new P-545 2nd generation PInano® high-resolution XY/XYZ multi-axis positioning system with higher linearity, simple operation, and easier access to advanced features in comparison to conventional analog piezo controllers. This PInano® II device features an easy-to-integrate low profile (20 mm), a long travel distance of 200 µm, and millisecond step time, making it ideal for super-resolution microscopy and imaging applications.
The C-891 from PI is a digital motion controller for PIMag® three-phase linear motors. The controller offers extensive functionality in operational data recording, wave generation, ID chip support, and extensive software support. With one motor and one sensor channel, the device is capable of sine-commuted operation, field-oriented current control, and automated detection of the motor phase.
Piezo nanopositioning stages offer high-resolution and scanning speed, making them useful for super-resolution microscopy and optical trapping. The P-563 PIMars XYZ-Stages are designed with a parallel-kinematics arrangement with higher precision and responsiveness compared to nested or stacked multi-axis positioners.
The FMPA is a high-speed 12-axis automated silicon alignment system based on a highly specialized digital motion controller (E-712) and a hybrid alignment mechanism to achieve the required long travel ranges without sacrificing stability, resolution, or alignment speed.

Nanotechnology uses the concept that constant velocity will get you to the destination faster than constantly stopped traffic. One technique puts this concept into practice via a fast nano-focus device based on a piezo-ceramic actuator embedded in a flexure guided lens positioning mechanism.
As advances in computer performance are implemented, extraordinary performance levels will come from the use of silicon photonics, or the integration of optical circuits on semiconductor wafers, instead of the use of electronics.
The performance of precision metrology equipment such as coordinate measuring machines (CMM) depends on highly accurate, repeatable, and controllable motion systems and position sensors. Air bearings have played a critical role in the development and construction of CMMs and other metrology tools. They are inherently frictionless, highly stable, and feature geometric precision straightness and flatness for linear bearings.
The need for advances robotics with high precision and alignment requirements continues to grow in the automotive industry. Many traditionally used articulated-arm robots are fast and can handle heavy loads, but they lack positioning accuracy. In the past, hexapod parallel kinematic robots were considered overkill for the automotive industry. Now, however, the situation is rapidly changing. This white paper describes the major benefits that hexapod 6-axis parallel machines have for conventional robots in automotive precision assembly lines.
When controlling motion at the sub-micrometer or nanometer levels for alignment and handling applications, it is imperative to have high reliability, robustness, minimized latency, and high-speed synchronization with external devices to reach sub-micrometer path accuracy. The higher the dynamics and throughput targets of a multi-axis precision motion system, the more holistic the design approach must be in order to achieve success. A systems approach where the mechanics, control electronics, and software are designed by the same team provides a great amount of benefits for the user.
As hexapod motion and positioning platforms become more mainstream technologies, their applications have expanded into medical fields such as dental biomechanics.
