HIGH ACCURACY POSITIONING HEXAPOD

SURES hexapod is a very high accurate and stiff positioning system. It allows the adjustment and the set up of objects of up to 500 kg with high resolution and low cross-coupling (parasitic motions).

SURES hexapod is particularly adapted to the fields of space observation, astronomy and telescopes. For example it can align M2 and M3 mirrors on ground-based telescopes to realign them correctly to compensate the deformation of the structure due to gravity changes and temperature variations during the night.

The mechanics and electronic components of SURES hexapod are designed to work in cold environment as most of ground-based telescopes are installed on top of mountains in high altitude.

CONTROLLER

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, piezo) coupled to various encoders technologies (absolute, incremental, linear, rotary).

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.
