COMPACT HEXAPOD FOR HIGH ACCURACY POSITIONING

BORA hexapod is a compact 6DOF parallel kinematics system for the positioning and adjustment of precision elements with a resolution of 0.1 µm.

BORA hexapod meets the most demanding criteria of the optics and nanotechnologies in terms of resolution, accuracy, stability and size.
Its dimensions allows an integration in a small environment, for instance at the tip of a goniometer for an application on synchrotron beamline, or on an optical ground support equipment to align and calibrate space optics.

BORA hexapod can be used in any orientation: vertical, horizontal, upside down…

OPTIONS

High vacuum compatibility down to 10^-6 mbar
Clean room ISO5 (class 100)

A HIGH-PERFORMANCE CONTROL CENTER

Controlling a parallel kinematics mechanism such as a hexapod requires fast and numerous calculations to transform the position instructions into motor current set points while permanently securing the motions.

For this, all our hexapods come with a high-performance control rack interacting with either our Graphical User Interface (GUI) or optionally directly with your software environment through an Application Programming Interface (API).

A COMPLETE AND FLEXIBLE SOLUTION

Our racks are made with:

■ a powerful multi-axis Delta Tau industrial controller
■ drivers sized to meet the needs of each application
■ input-output modules allowing various interactions with the hexapod environment.

Our robust and flexible controller solutions can be adapted to different types of motors (DC, brushless, stepper) coupled to various encoder technologies (absolute, incremental, linear, rotary).

Our controllers are compatible with our hand-held control unit in option.

CHOOSING THE RIGHT HEXAPOD FOR YOU

Symetrie offers a free software, HexaSym, that makes it very easy for you to check the possible travels and load capacities of each hexapod in their range. HexaSym will allow you to select the most suitable product for your application and to test a variety of possible configurations with it.

HELP FOR HEXAPOD CONTROL

Thanks to an ergonomic Human Machine Interface (HMI), SYM_Positioning hexapod positioning and control software offers simple commands from the home screen, but also generations of movements using specific files. In addition, the center of rotation can be easily changed in the software.

SYM_POSITIONING ALLOWS:

■ Safe movement control
■ Position display in real time
■ Generate position sequences
■ The configuration of the center of rotation
■ Configure repositories (coordinate systems)
■ Configuration of limits (position, speed …)
■ API (Application Programming Interface)
■ To be interfaced in C, LabVIEW, EPICS, SPEC, TANGO, Python, Matlab …

CUSTOMIZATION

Symétrie has the knowledge and solid experience in software development, which means that we can tailor our software to your specific needs.

HEXASYM SIMULATOR

HOW TO CHOOSE YOUR HEXAPOD?

Thanks to this free simulation software, it will be very easy for you to check the possible travels and load capacities of each hexapod in our range. HexaSym will allow you to select the most suitable product for your application and to test a variety of possible configurations with it.

TESTING SEVERAL PARAMETERS

With HexaSym simulator, you can test cumulative travel ranges on several axes simultaneously, including the “worst cases” of your applications. It is also possible to change the center of rotation, to define different reference frames, to vary the orientation of the hexapod (vertical, horizontal, other) and the payload.
HexaSym also includes a 3D visualization that will enable you to see how the hexapod moves according to the commanded positions, as well as sliders allowing you to control movements more immediately.

AND FOR SPECIFIC HEXAPODS

It will also be possible to use HexaSym for our specific hexapods, for which we will provide you with a configuration file compatible with the simulator.
