Simple and Affordable Hexapod
The PUNA hexapod is designed for precision positioning applications in research and industry while keeping within an optimized budget.
Despite its affordability, the PUNA hexapod offers impressive capabilities, including a resolution of 0.5 µm in translation and 5 µrad (0.0003°) in rotation, with a payload capacity of 25 kg.
A high-performance control center

Controlling a parallel kinematics mechanism such as a hexapod requires rapid and numerous calculations to transform position instructions into motor current set points while ensuring motion security.
All our hexapods come with a high-performance control rack that interfaces 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 control racks are designed with:
- A powerful multi-axis Delta Tau industrial controller
- Drivers sized to meet the specific requirements of each application
- Input-output modules that enable various interactions with the hexapod environment
Our robust and flexible control solutions can adapt to different types of motors (DC, brushless, stepper) and work with various encoder technologies (absolute, incremental, linear, rotary). Additionally, our controllers are compatible with an optional hand-held control unit.
Choosing the right hexapod for you
Symetrie offers a free software, HexaSym, that makes it easy to check the travel ranges and load capacities of each hexapod in their range. HexaSym allows you to select the most suitable product for your application and test a variety of possible configurations with it.

Help for Hexapod Control
Thanks to an ergonomic Human Machine Interface (HMI), the SYM_Positioning hexapod positioning and control software offers simple commands from the home screen, as well as the ability to generate movement sequences using specific files. Additionally, the software allows for easy adjustment of the center of rotation.
SYM_Positioning features:
- Safe movement control
- Real-time position display
- Position sequence generation
- Center of rotation configuration
- Repository (coordinate system) configuration
- Limit configuration (position, speed, etc.)
- API (Application Programming Interface)
- Compatibility with C, LabVIEW, EPICS, SPEC, TANGO, Python, Matlab
Customization
With extensive knowledge and solid experience in software development, Symétrie can tailor their software to meet your specific needs.
HEXASYM simulator
How to choose your hexapod?
Thanks to this free simulation software, HexaSym, you can easily check the possible travel ranges and load capacities of each hexapod in the range. HexaSym allows you to select the most suitable product for your application and test a variety of possible configurations with ease.
Test several parameters
With the HexaSym simulator, you can test cumulative travel ranges on multiple axes simultaneously, including the “worst-case” scenarios for your applications. The software also allows you to:
- Change the center of rotation
- Define different reference frames
- Vary the orientation of the hexapod (vertical, horizontal, other)
- Adjust the payload
HexaSym includes a 3D visualization feature that lets you see how the hexapod moves according to the commanded positions, along with sliders that provide immediate control of movements
And for specific hexapods
It is also possible to use HexaSym for specific hexapods, for which we will provide you with a configuration file compatible with the simulator.
