A multi-axis precision motion system with higher dynamics and throughput targets must have a more holistic design approach to achieve success. There are many obvious advantages to the user when the mechanics, control electronics, and software of a system are designed by the same team.
Many laser micromachining and micro processing engineers face challenges of delivering laser pulses to a workpiece with a high degree of accuracy and repeatability, among other attributes. This article discusses how these issues can now be solved with PI’s motion/CNC controller technologies.
Hexapod micro-motion robot technologies provide all six degrees of freedom in a stiff, compact, and high-precision structure. This app note discusses how the functionality enabled by a compact 6-axis micro-robotic hexapod system provides precise manufacturing and lens alignment in advanced cameras.
The engineers at Google have taken steps to optimize the motion and image stabilization algorithms in their Pixel 2 camera, which has been integrated with PI’s H-860 high-speed hexapod system that accurately simulates motion with 6 degrees of freedom and results in pinpoint-accurate crisp images.
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.
The performance of precision metrology equipment 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.
The need for advances robotics with high precision and alignment requirements continues to grow in the automotive industry. 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.
Vacuum applications, and technologies that can only be applied in vacuum or cryogenic environments have grown in importance within scientific research and industry applications. Optics technologies use vacuum environments to manufacture components such as fiber laser optics and sensitive detectors. Other applications that use vacuum environments include small epitaxy processes, semiconductor manufacturing, and X-ray or UV applications.
With the aim to cause patients as little discomfort as possible, minimal invasive surgery (MIS) techniques use endoscopes integrated with a miniature drive to achieve variable focusing so that objects can be in sharp focus at all times. These endoscopes are used in larynx diagnostics or laparoscopy where optics and special instruments can then be introduced to the abdominal cavity through working trocars. Patients will then experience less post-operative pain and are able to be discharged earlier from the hospital. This application note describes the focus and zoom control functions within these miniature drives, and provides information on available PI piezo miniature drives for endoscopy applications.
