Parallel-kinematic design for six degrees of freedom, making it significantly more compact and stiff than serial-kinematic systems, higher dynamics, no moved cables: Higher reliability, reduced friction.
Extensive Software Package
The software package included in the scope of delivery allows integration of the system into virtually any environment. All common operating systems such as Windows, Linux, and macOS as well as a large number of common programming languages such as Python, MATLAB, and NI LabVIEW are supported. Thanks to sophisticated program examples and the use of software tools such as PIMikroMove, the time between starting integration and productive operation is shortened considerably.
Brushless DC Motor (BLDC)
Brushless DC motors are particularly suitable for high rotational speeds. They can be controlled very accurately and ensure high precision. Because they dispense with sliding contacts, they run smoothly, are wear-free and therefore achieve a long lifetime.
Removable magnetic plate
Accelerate your workflows. The next workpiece can be prepared parallel to our automated process step. The removable magnetic plate can be disassembled quickly without tools and subsequently reassembled accurately each time.
PIVirtualMove
The simulation software simulates the limits of the workspace and load capacity of a hexapod. Therefore, even before purchasing, you can check whether a particular hexapod model can handle the loads, forces, and torques occurring in an application. For this purpose, the simulation tool takes the position and motion of the hexapod as well as the pivot point and several reference coordinate systems into account.
Application fields

The cables fixed to the H-811.F2 are 0.5 m long respectively.
The cables fixed to the H-811.F2 are not drag chain compatible.
Connecting cables are not included in the scope of delivery and must be ordered separately.

When measuring position specifications, typical velocity is used. The data is included in the delivery of the product in the form of a measurement report and is stored at PI.
The maximum travel ranges of the individual coordinates (X, Y, Z, θX, θY, θZ) are interdependent. The data for each axis shows its maximum travel range when all other axes are in the zero position of the nominal travel range and the default coordinate system is in use, or rather when the pivot point is set to 0,0,0.
At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.

The need to align devices down to nanoscale accuracy is arising in many fields. Optical components such as the lenses or lens assemblies in small cameras, or even the CCD chip itself, need to be positioned with ever more precision.
Hexapods are systems for moving and positioning loads in six degrees of freedom, in three translational and three rotational axes.
When it comes to throughput and production costs in testing, assembling, and packaging of photonic devices, alignment is one of the most significant cost factors. For maximum performance, the optimal combination of accuracy, speed, and intelligent automation is needed.
What do optical components and glass fibers in photonics, mobile devices, and high-quality wristwatches all have in common?
